    With all the recent power outage by PGE this portable battery power generator really come in handy. I have it ready to use to charge my phones and run small electronics gadgets. Or use it lights. It’s plenty enough to run routers. I have a portable solar panel that I charge during the day. I like the wattage usage monitor it helps to see charge state of the devices. Comes with plenty of 12V and 24V DC outputs, 2 Standard USB, 1 Type-C Quick Charge USB, 12/8A cigarette lighter port, and the two AC output sockets. It also good design that these are independently control. The light in the back is plenty enough to light up you room when power is out. It’s fairly light only around 7-8 pounds. Very light compare to those lead-acid portable battery generator. I’d recommend for those that live in NorCal or where utilities outage is common. Or just need extra juices for your electronic gadgets on the go.

     My wife insisted I take a video of this, I think she was more excited about it than I was. The video just shows some of its cool features. First thing I did when I got it was make sure to fully charge it and test some devices. Charges pretty fast, my main reason for getting it is the ability to use Solar to power it and in the event of an emergency I can keep the phones charged and use its built in light. However I also used it to charge all my sons remote cars and a few of my drones. I think we spent 3 or 4 hours out in the field using this to charge stuff. Its light, much lighter than I thought so its easy for anyone to carry around. All in all I like it, I think its a great device to have. I will be getting a solar panel soon to use with it for even longer excursions.

    Bought this to use for power in my small cabin. Came with AC power charger only but I wanted to hook up to an old solar panel I had for charging. The manual does okay with specs but does not give any info on how to actually hook up solar or what size the in-port is. I decided to contact their customer support. I wasn’t expecting an immediate answer as it was 9pm at night. To my surprise my question had been answered in an hour with exact specs on how to hook up solar! I ordered the adapter ($10) from Amazon and am now solar charging. So what their user manual lacks in detail was certainly made up by fast customer service and that is worth a lot and will keep me coming back for more Prymax products.

    I own the Phillips Respironics Dreamstation. I bought the wrong DC converter for it as recommended to get a DC converter. So i used it camping on A/C using the normal plug. I turned off the heater for humidity and it didn’t use a bar of power after 7 hours of use. It has a digital display of wattage output, it went up and down from like 8 to 15 watts with every breath, when i turn up the heat it goes 150 plus. i used it twice has one bar gone with no heat, not sure how fast it would go with heat might be fast. 4 out of 5 power bars left after two night with a/c plug not d/c converter plug. I suppose it would be even more efficient with a D/C converter idk.

    I wanted an emergency power pack when I can’t use my generator. This is great for power outages, camping, in an apartment building or anywhere else you can’t power up a generator. It is lightweight since there is a lithium battery instead of a gel cel. It also has so much more stored capacity than a gel cel. It has 298Wh! This means that I could power a 100 watt light bulb for almost 3 hours. LED lights use about 12 watts that produce the equivalent amount of light may use 12 watts. This means I could power light up a whole room for 24 hours or three rooms for eight hours. If you plug in a solar panel, you could basically have unlimited lights. It has outs for 110V plugs, cigarette lighters, and USB plugs. I love this thing.

     Great little light weight portable power machine! It is very light weight, small in size, very powerful – 298 watts.We bought this to go camping, road trips and general use around the house. We get power outages here that can last a few hours so it will be nice to have a backup.It has a 110V AC Plug or 12V DC Plug. I was able to charge our phones, blow up our air mattresses, connect lights, charges tablets for kids and as you can see in the pics, connect a vacuum to get the dirt out of our tent. It was a boat in only campsite so having made it very convenient vs blowing up everything on the boat and then hiking it back to the site.At first startup it makes some noise but after that it is very quiet.Can recharge unit with 110v wall oulet, 12v car outlet, and 18v solar panel.It comes with a flashlight on the back which was nice for camping.

    I live in a northern Californian’s fire area, when notice was given, that our electricity was going to be turned off for a few days, I looked for a unit that I could use to charge cell phones and my laptop. I also read that it could powered a CPAP machine. So I made an order for the PRYMAX Portable Power Station, 300W Solar Generator 2019 Updated 298Wh CPAP Backup Battery Pack with LED Flashlight,110V/300W Pure Sine Wave,AC Outlet, QC3.0 USB,for Outdoors Camping Travel Emergency. This unit came prior to the blackout and I was able to give it a full charge before use. After a a few days of use which I loved using, the ac plug stopped working just when the lights came back on. I called amazon on a Friday evening and I was told the company would contact me. A customer service rep at Hometal Direct By the name of Cindy contacted me via amazon text message, within hours of my message. After exchanging several message back and forth over two days, I was requested to send a video showing the units control panel and the use of the AC plug that yielded no power, by plugging in my laptop into the unit and then into a wall socket and showing the power light on my laptop. I recorded this video and tried to send it via amazon messenger, it was too large. My grandson loaded it to YouTube, so all I had to do was send the link to Cindy. This took me several tries using amazon messenger as each time I’d send the link it was deleted from my Amazon message. Trying for two days to send this link and several tries, Cindy kept me positive and reassured me this issue would be resolved . She sent me a message with an external email address to use and by Thursday of the following week,I was finally able to get the video to her. To make a week long story short. Cindy did see the video, however it didn’t show the needed coverage of the control panel . I was asked to try again. After one week and several tries and having my information deleted within amazon messenger, I became extremely frustrated, my grandson had gone back to his home and I was left to figure out how to get this second video uploaded to YouTube, which I had no idea of how to do. Reaching my wits end, frustrated with the whole thing, I called Amazon on Friday and requested a refund. Cindy had held my hand every step of the way. She treated me with care and understanding directing this non-technical person as best she could. Something I don’t find too much of these days. As a 72 year old woman I know customer service when it happens and this was above and beyond. Thinking this was the end of it, case closed. Cindy sent me this message:“Thank you for your quick reply. I am really sorry for the inconvenience brought to you.In this case, I don’t know what I can do for you. The only thing I can think of is to send you a replacement right away free of charge within my authority and you do not need to return the old product to us, which will save your time and energy. We sincerely hope you could be happy with Pry max product and service. Could you please give me your address? So I can send you a brand new product.We highly appreciate your understanding. Look forward to your reply.Best regards,CindyPrymax customer support “This is true Customer “CARE” , This is above and beyond . This touched my heart and has given me faith there is a company that cares about their customers and believes in giving good customer service, like in the days gone by! Prymax is such a company. Prymax puts their customers above the bottom line.Thank you Cindy , Thank you very much you are the true meaning of what customer “CARE” is about.Diane

    original review on 8/18/2019. After 4 hours using this with my dreamstation while camping, it was completely drained. did not meet my expectations.8/27/2019 Updated Review:I wrote the negative review after coming back from a camping trip and was disappointed it didn’t last. I initiated a return and prymax customer service reached out to me and pointed out a few things to me. I have a phillips dreamstation auto cpap. with the heat and humidifier on, it draws about 95w on AC. customer service pointed out to me that on DC i would get a much longer life as mentioned on the description, which I admittedly did not read. Under her suggestion, I purchased a 12V DC power cord for the dreamstation and tested it over the last few days.I have to say that the first day on DC power, 7 hours of sleep it only used 1 bar out of the full 5 bar. I am now on day 3 and there is still 2 bar left. This is with heat on 3 and humidity on 3, which is my home setting. I am now confident that I can get a week out of this if I’m out camping. I am changing my review to a 5 star because of the customer service and the performance of the power station exceeded my expectations. I will be keeping this unit.

     I ordered this 300W generator for emergency and outdoor use. It’s just the perfect generator that I was looking for. reasonable price, portable, light weight, and easy to operate. It comes with lot of outlets, ports for multiple charger at the same time. Use it with outdoor lighting, mini fridge, computer and etc. It’s also perfect to use when power outage at home. We also use the generator outside for camping and to the beach. Easy to carry out. unlike the other heavy generator, It’s light weight and easy to carry to everywhere as needed. I really happy with it.
