    I’m a 100% full time single parent with 2 teens. And with teens you know that means a lot of electronic devices. I need things that work and things that simplify my life. The Jackery 300 has been one of those purchases. It’s not only reliable but really easy to use.Most power outages are not very long lasting. So, I didn’t want to fool with a generator. I imagined how I’d have to check a generator every month. The maintenance. Wheeling the heavy unit around. Getting & storing fuel. Having enough fuel. Making sure the fuel lasts. Struggling to pull start it. The fumes from running it. The loud noise when it actually does run. Not to mention, an easy thousand plus bucks to buy one. All that seems overwhelming for more than 99% of our needs.If the power goes out, no stress, we just grab the Jackery. It’s practically silent and light enough to move around by just about anyone. Is the Nintendo Switch low? No problem. Your Chromebook? Want to run the PS4 or Xbox One? No worries. Your phone, watch, tablet – again – zero stress – just plug it in. Wa-la, problems fixed.It can run fans and a whole host of other devices too – not just your typical tech electronics. During tests, we ran our cable modem / router for many hours to provide WiFi. It accepts regular wall socket type plugs too. Also during our tests, it ran a 55” inch TV along with a PS4 Pro for over 1.5 hours. We even used a disc based game to use even more power. With a smaller screen it’s closer to 2.5 hours. Downloaded games use less power too. The Nintendo Switch uses even less. All that exceeded my expectations. SUPER EASY.Now let’s talk camping, car trips and other family outings. Again, the Jackery 300 is clutch. There’s no need to be concerned about limited outlets in the car to charge or none available at a park or campsite. If I’m going camping – this will always come with us. How nice to run a fan inside the tent during the summer nights! This will instantly get you “glamping”. Tons of options here.The Jackery 300 is also fairly compact and lightweight and weighs in right around 7 1/4 pounds. It’s significantly smaller than the size of a small Igloo Playmate Cooler that I have used as a lunchbox for years.I appreciate that’s it’s powerful but doesn’t take up much space. It’s interface is solid and super easy to understand. All around it’s very intuitive and you can tell everything is very well thought out. It also has you covered with a wide variety of plugs from AC outlet sockets to a car power port to USB-A and the newer USB-C. It even comes with a quality zipper pouch to store your charging cables.Another thing about Jackery is it’s a widely recognized brand with a proven quality track record. Many no name brands are out there that don’t include the device and circuit protections Jackery units do. The last thing I want to do is buy another power station after frying our expensive electronics. I am a believer that when you buy cheap, you often buy twice. This is the top brand in this category of products. I definitely don’t have time to mess with low quality el cheapo brand units.Without boring you with detailed specs, the Jackery 300 produces a very clean stream of power – which is exactly what you want. In layman’s terms, it’s a smooth stream without all the peaks, valleys and surges that can harm your devices.One thing we tend to forget until something happens is what we have on hand for emergencies. This is definitely on my list. If we need to evacuate for any number of reasons (storms, fires, Godzilla – the weirdness of 2020) the Jackery 300 is a must take item.Those in the Prepper, Bug Out and Emergency Preparedness minded communities should be all about this. It can even be fully recharged in just a few hours with the optional Solar Saga solar panel. It can of course be recharged too by your standard home outlet or even your car – and it doesn’t take forever to do it. It also doesn’t alert everyone far and wide that you have power. That might be handy while in a non permissive environment or even a noise restricted campsite.In today’s age and with everything going on, this should really be a staple device in our homes. I feel better just knowing it’s on hand. It’s one less thing to worry about.Lastly, I plan on buying another for my senior citizen mother too. That alone should say a lot!TLDR: Zero regrets with this purchase. It’s an absolute no-brainer.

    [Update: Jackery announced on 1/28/2021 that the updated Explorer 300 can now be charged through the 60W USB-C PD and be used in parallel with the 90W AC wall charger. This provides for a combined input of 150W, nearly cutting the charging time in half!]Back in April, I purchased the Jackery Explorer 1000 and the Goal Zero Yeti 500x later as a result of 2019’s fires. Coincidentally, this year’s fires on the entire US west coast is actually WORSE with new records broken! I cannot stress how important it is to be prepared for emergencies, and with a baby and young boy in our household, I wanted to ensure we have a crucial refrigerator running to store milk, medication, and whatever else we needed.There has been an increase in people taking emergency preparation more seriously.I had since invested in several car freezers (favorite is the Foho 34qt BCD-32) as part of my emergency toolset. When Jackery announced the Explorer 300 (E300) with a special launch price and some improvements over the Explorer 1000 (E1000), I jumped on it for one simple reason: my little boy loves camping, and I wanted him to have a mini-Explorer of his own (actually, I wanted another backup battery, but don’t tell him that.) Literally, the E300 is a mini version of the E1000, and it looks awfully cute to have my son and I stand next to one another holding our own Explorers!Right off the bat, the two models are very similar to one another, and so I will be re-using much of what I had already written for the Explorer 1000. The E300 is the direct successor to the company’s Explorer 240 model.CELL MANUFACTURERSToday’s devices use Lithium-ion (Li-ion) and Lithium Iron Phosphate (LiFePO4) cells so they can pack more power in a smaller package and weigh less. However, Li-ion (which the Jackery is made with) also is more volatile whose risk increases as more cells are packed together. The quality of the battery cells and the BMS (Battery Management System) are crucial for safety.- Battery storage capacity is measured in Wh, and power output is in W (Watts)- The higher the Watt-hour (Wh) capacity rating, the more dangerous the battery could become if not handled rightBattery cells made by LG and Sony are among the best in the hobbyist world as are Sanyo/Panasonic, Samsung, and BAK Battery. Jackery Explorer 1000’s batteries are made by LG and BAK, but the E300’s are by EVE Battery. I do not have much information about the new, publicly-traded manufacturer’s safety record, however, but going by Jackery’s track record, they likely would not have selected a poor company to provide fuel cells for their power stations.During my years of research, I found that use of lower-quality batteries could pose a serious risk to life and property and should become a crucial part in deciding what to buy.IN A NUTSHELLJackery Explorer 300 is a relatively light power station with a professional-looking exterior and flashy, orange color scheme, and is backed by a company that appears, from the stories I have read (and personally experienced), to take customer service seriously. The batteries are made by a manufacturer I do not know much about, but their weight is an indicator that they are likely good quality. The 300W of energy (and peak of 500W) provides enough power for a small amount of electronics and small appliances, such as a laptop, television, mini fridge, medical device (like CPAP), and car freezers, but will NOT work for most rice cookers, and definitely not for a vacuum, water boiler, or circular saw.Like the bigger E1000, the hard, plastic material used to help shed weight (and cost) could be prone to cracking from hard falls or bumps, potentially exposing the Lithium-Ion batteries to puncturing. The fixed carry handle unfortunately cannot be folded, making it not ideal for packing things on top.Functionally, this is an excellent, portable power station with a multitude of AC and DC outputs, is solar charging capable with MPPT built in, and has a battery management system (BMS) to help ensure safety. Equally important is its verified claim of a pure sine wave – not modified – AC Inverter to produce clean electricity for sensitive electronics. Like Goal Zero Yeti 500x, Jackery finally upgraded the E300 with a USB-C PD with a 60W output. The E1000 only produces 18W. This makes it very useful for charging supported laptops.Jackery is one of Amazon’s top sellers in the portable power station category with good customer service and reasonable prices, and as this is no longer my first experience with their products, I have no hesitation to recommend its latest product.PROS- At 293 Wh capacity, it is an improvement over its Explorer 240 model and falls in-between Goal Zero’s Yeti 200x and 500x capacities– Capacity to power a 30″ LCD monitor and Mini PC for 3-5 hours, a Toshiba 50″ Fire TV for almost 2.5 hours- Pure Sine Wave AC Inverter capable of continuous 300W power (and 500W peak) – More details later- Very well-priced at $349 at launch- Can power AC and DC (USB/12V Car adapter) at the same time (as long as they draw less than 300W combined)– Laptop, tablet, phones, lights, fans, CPAP medical device, projector, TV, mini refrigerator, speaker, camera, DSLR battery charger, and SOME rice cookers- USB-C PD port outputs 60W- Can be used while charging- Faster charging with MPPT controller (Maximum Power Point Tracking)- Informative LCD with LED backlight– Total power coming in (via solar panel or AC adapter)– Capacity left (as a percentage)– Total power (AC and DC combined) being used— Suaoki G500 displays the Wattage separately for DC and AC, which I prefer– Unfortunately, estimated hours to full charge or empty is NOT shown- BMS provides built-in overload, overcharge (automatically stops charging when the device is full), and short-circuit protection– Multiple fans to keep the station’s temperature safe- VERY compact at 9.1″ x 5.2″ x 7.8″, though the higher-capacity, slightly larger Goal Zero Yeti 500x is still my favorite for its size and capacity- Portable at just 7.1 lbs- Bottom is well-protected by bright-orange, non-slip feet- Carry pouch included to hold AC charger and cables- Cigarette socket cable included- Unexpectedly good customer service– Technical support was excellent in answering all my questions- 2 year warranty- Clear, well-written manual, though details were scarce– Goal Zero’s manual, on the other hand, is VERY detailed and helpful- Company is based in CaliforniaCONSThe E300 shares almost all the same design problems I disliked about the E1000, but also adds some improvements.- Batteries are not made by a globally well-known, Tier 1 manufacturer– My unit came with fuel cells by EVE Battery, a China-based, publicly-traded company- No Anderson input port for solar charging– You charge with an (optional) Anderson-to-8mm converter cable instead- Fixed carry handle cannot be stowed away– Makes it difficult to stow things on top at the back of a trunk– Upward-curved top (underneath the carry handle) does not allow small items to be temporarily stored on top- Hard, plastic material makes the power station lighter, but could be prone to cracking from hard falls or bumps– Given that Lithium-Ion batteries become more volatile as capacity increases, one should handle the product with care- Although the exterior looks very professional, once I saw the Goal Zero Yeti 500x, I fell in love with the Yeti’s design- Power buttons can be accidentally turned on/off through a single press (ie. while packing away your camping gear)– Can lead to accidentally turning on/off the output during transport– May unexpectedly find battery fully drained when you need it– Suaoki requires you to hold the DC or AC button for 2 seconds before it turns on/off that output, helping to minimize accidental presses– No automatic power off once no power is drawn/station has become idle- AC power brick is flat and large- No built-in flashlight or SOS signaling that the E1000 includes- Display is not as informative as I’d like– Only shows battery charge level, input and output wattage, but no estimate of time remaining to full charge or to empty- Multiple fans turn on during high peak and can be too noisy for some- Battery cannot be replaced. This can lead to unnecessary landfill waste- Cannot be daisy-chained to other Explorer 300/1000’s to extend battery capacity– Some Goal Zero stations can be hooked up to other ones so power can be provided for an even longer time without needing to switch- Not waterproof. Keep it away from water splashes, rain, and pool!– Lithium and fire or water can cause serious damage or injury!- No master power off button to turn off ALL outputs at the same time– You have to manually switch off each type: DC, AC- No carry bag for the power station itself is included– BUILT Willis 11″ Insulated Lunch Box (ASIN: B08D6VMGG1) fits the E300 perfectly well (with usable pockets) when the Jackery is put on its sideINPUT PORTS- 1x 8mm– Accepts up to 90W– Max 12-30V and 8A with no minimum wattage— WARNING: Do NOT use a power source/solar panel that exceeds 30V or 8A!—- Be mindful that solar panels that are daisy chained in sequence/series may output more than 30V combined!– Can be used for solar charging— MPPT charge controller is built in— I recommend using a panel that’s between 30W – 100W at 18V (with the right Amps to equal 100W)—- If you attach a 120W solar panel (with 12V x 10A = 120W), it will charge at only 90W— I did not test solar charging as California is currently blanketed by smoke from the massive fires all over the west coast— Jackery SolarSaga 100W charged the Explorer 1000 at an excellent 69-88W of input. I expect it to be similar with the E300OUTPUT PORTS- 2x AC with 3 prongs (120V)– Inverter can handle a continuous 300W, peaking at 500W. More on that later– Pure Sine Wave Inverter— Ensures clean power to protect against damage to sensitive electronics— Generates less heat— Note: Some manufacturers claim to be Pure-Sine when they are actually Modified or Square Waves- 1x Cigarette socket (12V, max 10A)- 1x USB-C PD (5-20V, max 3A, max PD 60W)– PD (Power Delivery) allows a device to be charged with up to 60W through the USB-C interface- 2x USB-A (5V, max 2.4A, max 12W)– One of them is a QuickCharge 3.0 for rapid charging of compatible devicesUSAGE- To turn ON or OFF the Car/USB (DC) or AC outputs, press the corresponding button– Note: This single-press (without hold) can lead to accidentally turning on or off the power station- To reset an Error condition that’s shown on the LCD (ie. AC port is Overloaded), turn OFF the respective AC or DC output, and back on- To reset the Explorer, hold the DISPLAY button for 10 seconds- Li-ion batteries have 500 charge cycles before capacity drops to about 80% from when they were new– Product could, in theory, be charged up to 2,000 cycles — about 1/4 of total capacity is lost every 500 cycle- Unlike LiFePO4 batteries, Li-ion can operate only in temperatures between 32-104F (0-40C)– Jackery’s Battery Management System (BMS) prevents:— Recharging in temps outside of 32 – 95F (0 – 35C)— Outputting power in temps outside of 14 – 104F (-10 – 40C)- Battery, like all Li-ion, slowly drains over time even when station is powered off– Could take 1-1.5 years to go from full to emptyCONTINUOUS VS PEAK OUTPUTThe Explorer’s AC Inverter provides a continuous output of 300W with a peak/surge of 500W- AC Inverter: Component responsible for converting battery (DC) power into AC for use by electronics- Continuous Output: As long as a device (or combination of multiple ones) does not exceed 300W, it can be used– Example: A TV that uses 100W can be used because it is less than 300W. You can add more devices as long as they do not exceed 300W combined– Example: A miter saw I have uses 1,800W, and because it exceeds 300W, it cannot be used- Peak/Surge: Almost every device temporarily draws more power when it is turned on. The highest amount it pulls during that time is the Peak/Surge. This Explorer can accept up to 500W– Example: A TV that uses 200W (continuous) may temporarily suck up 400W (peak) when powered on. Because 400W is less than 500W (peak), this battery will allow the TV to turn on at that level for a few seconds (any longer, and it might cut power as a safety precaution). After a few seconds, the TV then only uses 200W (less than the continuous 300W limit) until the battery is drained– Example: An unusual device that uses 250W (continuous) and surges to 1,500W when powered on would instantly be shut off by the Jackery. Why? Even though the device uses just 250W while already on, it jumps to 1,500W when powered on, exceeding the 500W surge limit of the JackeryCALCULATIONSThe below calculations are rough estimates as conditions, quality, and product age can vary.CHARGING TIMES- Wall charger: 4-5 hours– AC adapter was observed to provide 76W when charging level was at 37%– AC adapter will gradually charge slower as battery reaches full capacity (for safety reasons)- 100W solar panel: depending on weather conditions, it should take about 5-6 hours. I could not fully test this because the smoke from the California fires is blocking the sun– WARNING: do NOT connect panels sequentially or you may output too much voltage and fry the power station! Connect them in PARALLEL with a Y-Branch cable- Goal Zero Yeti 500x can combine its 8mm and USB-C PD ports for a total input of 180W. Neither the E300 nor E1000 can combine both inputsHOW MANY WATTS DOES A DEVICE US?- Calc: Watts used by device = Voltage x Amperage- If a vacuum is 120V and 9.5A, it uses 1,140WIf a device draws more than 300W for an extended period of time, the power station will shut off as a safety precaution. This can also shorten the battery’s lifetimeHOW LONG CAN A DEVICE BE USED FOR?- Calc: Hours available for device = Battery capacity (Wh) x 0.85 / Watts used by device– Generally, about 10-15% of power is lost during power conversion- If a device uses 60W, it could last up to 4.1 hours (293 Wh x 0.85 / 60W)- Amazon TV I have uses about 100W– If battery is full at 293 Wh, TV could run about 2.6 hours (293 x 0.9 / 100)HOW LONG DOES IT TAKE TO CHARGE A DEVICE?- Calc: Hours to charge device = Device’s battery capacity (Wh) / Input Wattage- If a laptop accepts 60W of input and its battery capacity is 200 Wh, it could take 3.3 hrs to charge (200 Wh / 60W)HOW LONG DOES IT TAKE TO CHARGE THE EXPLORER 300 WITH SOLAR?- Calc: Hours to charge battery = Battery capacity (Wh) / (Panel Wattage x [0.5 or 0.75])– In a perfect lab environment, solar panels charge at the indicated wattage (ie. 150W)– Expect to only receive 50-75% on a good, sunny day (ie. 75W – 113W), depending on environmental conditions, panel’s age, and component quality– Tip: Even if it is overcast, the panels will STILL collect solar energy. Keep charging!- If a solar panel is rated for 100W, it could take as fast as 3.9 hours [293 Wh / (100W x 0.75)] to chargeHOW DOES ITS CAPACITY COMPARE TO POWER BANKS?- Calc: Powerbank-equivalent capacity (mAh) = Battery capacity (Wh) / Voltage x 1000– 1 Ah = 1000 mAh- Explorer’s 293Wh at 3.6V is roughly a 81,389 mAh powerbank (293 Wh / 3.6V x 1000) or a 27,129 mAh at 10.8VTIPS- Always test your devices with the power station before you depend on it on the go- Lithium-ion batteries are volatile– To minimize fire damage to your belongings or loved ones, store the power station in the garage and not inside the house. Best storage is a dry, cool place, however– You cannot bring a battery of this capacity on a plane- With the right BMS, quality batteries, and other factors, the power station can be stored in the car while camping during a hot, California summer– Keep the battery out of direct sunlight. I usually store it on the floor of the car and crack open the windows a tiny bit– Do not USE in the car if temperatures fall below or exceed the battery’s rated, operating temperature (32-104F or 0-40C)Keep your car cigarette lighter with the power station — you could plug it into its 12V DC socket for starting a camp fire- If using a car charger, make SURE you only charge this station while the car is RUNNING. Otherwise, you’ll deplete your car’s battery and leave you stranded- If charging with a solar panel, be sure to keep the station out of direct sunlight as it could overheat– A solar panel is NOT required to use the battery– Explorer 300 uses the MPPT solar charge controller— Smarter, more efficient/expensive than PWM— Suitable for larger systems- Can be used and charged at the same time. Manufacturers’ recommendations for their own products:– Yes, that’s fine: Goal Zero, Jackery, Rockpals, nrgGo– No/Not advisable: Suaoki- NEVER charge the power station itself in below freezing temperatures, or you will damage the Li-ion battery AND potentially limit its overall capacity– You CAN use it to power OTHER devices because the generated heat will warm its battery enough to be within operating temps– At below freezing temps, keep it in an insulated cooler and connected to a power source (ie. solar panels). The heat generated by the battery will keep it running as best as it can- Turn off any output ports (AC/DC) that are not being used in order to conserve power- Do not use any power station in a tightly enclosed area as it can overheat- To prolong the battery lifetime while in storage, keep the battery fully charged every 3-6 months– Or, according to customer support, keep it plugged in when not in use and discharge it to 50% every 3-4 months– NOT using the battery for a very long time can actually hurt its lifetime– There is no “memory effect” in this station’s battery. It is better to NOT let it completely drainFINAL THOUGHTSThe Explorer 300 is another winner for Jackery in that it has made several improvements over its older, bigger brother, the Explorer 1000. I was disappointed to find out that its batteries are made by EVE Battery, a Chinese, publicly-traded company I have little knowledge of. The Explorer 1000, on the other hand, used either LG or China-based BAK Battery, both of which are excellent manufacturers. The company has shown time and time again that it takes customer service VERY seriously, and to me, that is a major plus. The 300W of energy (and peak of 500W) provides enough power for a small amount of electronics and small appliances, and is the perfect size for my little boy, the fellow explorer and camper.The hard, plastic material commonly used by power stations to help shed weight and cost (just like the E1000) could be prone to cracking from hard falls or bumps, and as such, this product should be handled with care – a puncture of the Lithium-Ion batteries could cause severe harm. The fixed carry handle unfortunately cannot be folded, making it more difficult to pack things on top.Jackery is one of Amazon’s top sellers in the portable power station category with good customer service and reasonable prices, and if the new EVE Battery manufacturer proves to be as reliable as other Tier 1 makers, I will have no hesitation to recommend its latest product.

    The media could not be loaded.

     After a bunch of research it seemed a lot of people used jackery for their power station, after so many good reviews I ordered the jackery explorer 300, I was happy that it took about 4 hrs to charge it to 100% from under 10. My plan for this purchase was to run my fridge in my truck, after some testing it runs my fridge for about 17hrs with a outside temp of 90ish F. I like that they have the pass by charging system so it is charging my 300 when my truck is on and during travel. Will def be getting the 100w solar panels later for better convenience.

    As an owner of several Jackery Explorers already (160, 240 and 1000) I was excited to see them offering the new Explorer 300. I do a lot of camping and nature photography during which I use these devices to power various pieces of equipment (cameras, lights, refrigerator, etc.). Immediately, I was impressed by the size of the Explorer 300 as well as the quick charging time. That is, it took only a couple of hours using AC to bring it from 38% to 100% and then when I tried using my Jackery solar panels it recharged in almost the same amount of time – that was a big surprise. With two 120 volt outlets I no longer have to use a power strip to connect multiple AC accessories. As my camper is rather small the fewer cables and connectors I have to bring along the better.My first use of the Explorer 300 occurred the weekend I received it when I used it on a camping trip in the local mountains. I used the Explorer 1000 exclusively for powering my refrigerator and the 300 for everything else. The 300 proved more than adequate for handling my lighting, laptop, mobile phone, fan, video camera, etc. and the following day it required only a couple hours to recharge using my Jackery solar panels. This represented a big advantage over my prior approach, because once the device was charged I could secure all my equipment inside my camper and go about my planned activities. As with my other Jackery products, the 300 is durable, well laid out and functions flawlessly. The Explorer 300 will now be my go-to power supply for all camping photography excursions, as it provides the optimum in power, flexibility, reliability and ease of use. Coupled with its small size and durability it has proven to be ideal for my needs and I could not be more pleased.

    I own the Jackery Explorer 240 and the 1000 models and have had great results with them, so I figured the new Explorer 300 would be an excellent power station too. It is interesting to note that the 240 and the 300 models are the exact same size (i.e. for a case or other needs). I tested the 12v outlet to see if it had regulated voltage output and when the battery was at 44% SOC (state of charge), the power was at 13.49 volts, so yes, it is regulated. This means it can run many electronics longer because they will not shut off due to low voltage. Using a Kill A Watt meter to monitor the Jackery 300 while powering it through the AC plug (inverter) it shows that this power station produced 248Wh which is about an 85% efficiency rating (this is from none professional equipment). The meter also showed that it produced 110.5 volts at 60.3 Hz. This Jackery also has a MPPT solar controller for more efficient charging, and charge times have greatly been reduced from the previous models. I did a test and charged both my 240 and my 300 from 10% SOC and it took 6 hours and 42 minutes for the 240, and only 4 hours and 7 minutes for the 300. This is well in the range of a total of 4.5 hour to fully charge the 300 as advertised by Jackery. Extrapolating the 240 to the same watt hours of the 300 I estimate it would take about 8 hours and 20 minutes to charge it. The 300 charged at an input of 76 watts at the start, and the 240 charged at an input of 39 watts at the start based on the display. It also has a Pure Sine Wave inverter for a cleaner energy supply unlike some other power stations. Cables are much better quality and are longer than the original Explorer 240 (7’ for the 300 vs 3.5’ for the 240). Jackerys are also known for their superior build quality, see below*.There are three things I would like changed in the Jackery 300, but they are very minor. I prefer a square or rectangular shape for efficient storage in my small Class B RV. I would also like earth tone colors for better stealth (I don’t need people knowing what I own and where to find it while I am camping). The Jackerys all have an orange coloring on them making them more visible than I like. The more important thing I would want to make the 300 a better unit is to have a typical charging port on it instead of the 8mm connection, such as an Anderson connection like the Jackery Explorer 1000 comes standard with.Pros:• Superior build quality*• MPPT controller• Pure Sine Wave 300 watt inverter (500 watt surge)• Quicker re- charge than past models (2x per my test)• Regulated 12 Volt outlet (at 13.5 volts)• Excellent Display showing % good, input & output wattage• Only 7 poundsNeutrals:• 500 charge cycles to 80% capacity (I prefer LiFePO4 chemistry)Cons (minor):• Shape (I prefer square or rectangular)• Bright Orange Color (I prefer neutral or stealth colors)• I wish for a more common charging port such as an Anderson connectorFeatures:• 293Wh Lithium Battery• Pure Sign Wave 300 watt inverter (500 W surge)• MPPT Solar Controller• Regulated 12 volt output 10A w/cover (cigarette plug)• Two AC outlets• Quick charge capability• Display with watts in/out & battery percent good• USB-C 60W• USB-A 3.0 Quick Charge• USB-A 5v, 2.4A• 8mm Input connector• Individual on/off buttons• Plastic Case• Rubberized feetIncluded in the box:• Warranty card• Manual• A small register card• Case for cables• AC Adaptor in 2 parts• Car Charger Cable for cigarette plug• Jackery Explorer 300 Power Station*There is an interesting video on YouTube where Will Prowse cut opened a Jackery and checked its interior built quality. This man is very knowledgeable with batteries and solar systems, check out his many video reviews. He found the Jackery to be extremely well designed with large gauge wires, quality soldered circuit boards, what appeared to be a superior BMS etc. He has looked at many other power stations and none were constructed quite as well. This video alone convinced me to purchase my first Jackery.

    I have a Respironics Dreamstation that seems to be set at 13lbs of pressure.I had it on from 11:30pm until 9am and it only went down from 100% to 76%. So I should easily get 4-5 really good nights of plenty of sleep (I figure 36-38 hours, so maybe 5 nights of sleeping 7-7.5 hours, but only 3-4 nights if I’m using a USB powered fan as well). I plan on waiting a week or two and then testing it one more time. I read online it’s best to store these at 80-85% capacity, but I don’t know if that’s true.NOTE: I am using the respironics DC cable, so it’s getting maximum efficiency.I got this for the upcoming hurricane season, since we went without power for 2 days last year (and many friends nearby went for 4-5 days without power). The price point seemed a bit better on the 240 model (saves $70), but I splurged. It came 46% charged, and was at 100% within 2-3 hours. It’s a little smaller than I expected and MUCH lighter (it feels like 3lbs max). I could totally fit this in a backpack if I had to, but it would be perfect for car camping. My next purchase will be an affordable/good value 100-120 watt solar panel, as I like the idea of free electricity; they seem to sell for $120-$150.I’d recommend this and a DC cable to anyone who has a CPAP.

    So far I am very impressed with this product. It arrived with around 46% charge and I was able to charge it to full in a little over an hour using the included AC adapter and a 60 Watt USB-C power delivery charger I have for my Surface Pro 7.The main reason I purchased the product is to power a CPAP, which it did very well. Some reviews had mentioned CPAPs, but the product information did not. The actual product documentation that arrived did estimate 6-21 hours for a CPAP with the Jackery 300. My limited testing with a Phillips Dreamstation CPAP on 11 with no humidifier indicates quite a bit longer. With the normal AC adapter it should run about 34 hours (see table for details). With the Phillips DC cigarette lighter power cable, it should run around 60 hours. Either way it should be able to power a 8-10watt CPAP without humidifier for a number of nights.The 60 watt power delivery port was able to charge my Surface Pro 7 from 26% to full fairly quickly while it was still being used. It was pulling 40-50 watts easily until it was recharged again (a little over an hour).The 18 Watt QC port worked well to charge my Samsung S9+ via a wireless fast charger as well.I then powered random things throughout the house to see how many watts they pulled and to drain the battery some more before charging and storing it. I may need to check out some of their larger products, but I might wait until they get 60 watt power delivery as well. That was a very good feature and could be very useful during rolling blackouts to charge it before power goes out again.

    tl;dr – camping with a CPAP that wants <=300W? Get this.I camp and wear a CPAP at night. I've spent the better part of 5 years looking for ways to do this. I've run extension cords from generators, hooked deep cycle batteries to inverters and marine power interfaces, and researched portable power options endlessly. My machine is an F&P ICON and specifies a 300W draw. I didn't want to deal with a generator and the battery contraption was a pain to maintain.This thing is a breath of fresh air. It's lighter than it looks, charges quickly, is easy to use, and handled the power load over the last few nights of a test run at home. The display is simple - power in, power out, and percent charge remaining. The controls are easy to manage for charging, DC out , and AC out. The ability to charge from two inputs simultaneously is incredibly cool. My test run was two nights on one charge with the CPAP in airplane mode - humidifier off. Each night took about 35% of the charge off, and it recharged fully in a few hours on the AC charger. If it holds up, this will be my single favorite piece of camping gear, and I'll be looking to add solar panels.

    The Jackery Explorer 300 is your perfect companion, whether you are camping, using the two AC power outlets for a small refrigerator and charging laptop to work remotely, or having a laid-back movie night in the park.  The Explorer 300 is the sweet spot of portable power on the market.  The design makes it light but powerful to run and charge various electronics, lights, and small appliances. Many have talked about how it is a great accessory while camping, which I will say will be my main use of the product.  However, the other evening I gathered a small group of friends, and we headed to our local park to enjoy a social distanced movie night.  The Jackery Explorer 300 made this more than possible while being easy to transport with a sturdy handle.  As you can see in the photos, the setup consisted of a 40-inch flat-screen tv, a Firestick, Bluetooth speaker, mobile hot spot, and of course, the Jackery Explorer 300.  Once everything was in place, the multiple output ports on the Explorer 300 gave us the flexibility of the devices that we could use and still have an open AC and 12v outlet handy in case of need.  Once everyone was settled in their chairs, we powered up the electronics, and for the next two and a half hours, we enjoyed a movie in the park, all powered by the Explorer 300. When all was done, we still had 40% of the charge remaining in the Explorer 300.  I will say the uses for this device are almost infinite; from camping, movies in the park, and the occasional need to charge my cell phone, the Jackery 300 can be used in every situation.  I have had many smaller battery backups and chargers in the past, but what I like about the Explorer 300 is the device’s flexibility and being lightweight.  Carrying it to and from the house and the car is easy.  The flexibility of outlet types meets every situation. Two AC outlets are great on the go, along with the 2 USB Type-A and one USB Type-C outlets.  I would recommend the Jackery Explorer 300 to anyone who wants reliable power in the woods or the city.  I next would like to explore the Jackery SolarSaga 100W Portable Solar Panel.

    I purchased a Jackery Explorer 300 Portable Power Station on 9-1-2020 and it arrived a few days later via FedEX. My decision to purchase the E300 was based on the results of my previous experience with a Jackery E160, E500 and a Jackery E1000. I found the Jackery Power Station to be very useful, easy to use and easy to charge with the Jackery SolarSaga 100W Solar Panel, AC Charger or the Car Port. I use the E300 to power my small electrical devices during the power outages that often occur after storms or traffic accidents in my area. The E1000 will take care of powering my Maytag Refrigerator/Freezer but I needed another power station and I chose one with more capacity than the E160 for some of the longer power outages.I have tested the E300 with several LED & CFL lights that can be used in table lamps and the best one is a 14W Grt Val 1500 Lum LED ‘DayLight’ bulb, It draws 20 Watts and the E300 will power it for 12-14 Hours from 100% to 10% battery charge levels. The fan will run part time and is very quite. I place the LED light bulb in a small table lamp and it can be moved as needed. You probably already have LED’s in your table lights so just use one of them. I also tested a Philips 11 Watt 1000 Lumens LED light for 6 Hours and the E300 charge level decreased from 90% to 60%. I also tested a 5 Watt Onite 400 Lumens USB LED light for 9 Hours and the charge only changed from 90% to 75%. Any of these three choices are a big improvement over my LED lanterns that start out bright but quickly dim unless you run them on low power. As a result of purchasing the E300 I have retired several of my D-Cell LED lanterns that were being used for the power outages and replaced them with table lamps, rechargeable LED Lights and flashlights with rechargeable AA & AAA batteries.I have a UPS to protect my desktop computer that gives me 20 minutes of runtime in a blackout but if I plug the UPS with the connected computer into my E300 I can extend the operating time at least two more hours. My internet also provides my telephone service and the U-Verse modem needs power or I lose telephone service. The Power Lift Chair can operate from the E300. The “Merlin@Home” Transmitter needs power to send pacemaker data and worked just fine when tested.I like having more than one power station because I won’t need extension cords for each device that I want to power and that also lets me place then in different parts of the house. The E300 has some new features that were not on the E240. The AC Inverter is now 300 Watts (pure sine wave), the 13.3 Volt regulated car port output has a nice cover and the USB output has 60W PD USB-C, QC3.0 USB-A, USB type A port (2.4A). The MPPT charger provides faster charge rates from solar (5.5H), AC (4.5H) and from a car port (5H).An important feature of the Jackery Explorer 300 is the pass through charging can be used to supply power continuously to a critical load by charging the E300 from the DC Carport on another Jackery Explorer. If the load on the E300 is 75 Watts or less the E300 will stay almost fully charged. The Jackery (E1000, E500, E440, HLS290, E240 or E160) can supply power until their battery is exhausted. This method will allow you to keep the E300 in a critical place without the need to move it outside to recharge by a Solar Panel or Generator. The other Jackery Explorer unit can then be moved and recharged as needed. The DC charging cable you will need is supplied with the Jackery Explorer 300.The E300 is much more useful than just for power outages and I am discovering more uses every day. The E300 provided power when the wife needed a heating pad while setting in a wheel chair a few days ago. I have a solid state Oscilloscope that the Jackery E300 can power for several hours and that makes one of my best pieces of test equipment truly portable. The E160 and the E300 are used to provide power for my Ham Radio equipment when operating at temporary locations.Two things that would help with my Ham Radio Equipment is the addition of Anderson PowerPole connectors on the DC input and DC output. This would help when charging the E300 and powering my radio equipment from the E300. The ability to turn off the “Auto-power off feature when the draw is under 10 watts” would really be handy. This feature is great for saving the battery but not so good when powering tranceivers that are monitoring an emergency radio frequency. You just might miss your call.For maximum battery power, charge Lithium-ion Batteries every 6 months to compensate for the self discharge and for longer life, charge before going below the 20% charge level.The Jackery Explorer 300 is well worth the price and is expected to provide excellent service for many years.Here are some photos of just a few of the items that the E300 can power.Jackery Explorer 300 Waveform; Heating Pad on Wheelchair; AA & AAA Battery Chargers; Rechargeable lights; Ham Radio Equipment; Jackery Explorer 300 with accessories; AC, DC & USB fans; Solar Charging in Morning Sun; Power lift Chair; Oscilloscope; AC, DC & USB Powered Lights
