    I cannot wait to to take this thing camping! I tested it out at home to make sure it would work for what I need and I have to say I’m impressed! I used the battery fully up, which wasn’t easy, and then I placed it in the window for 24 hours to see if it would charge. I was shocked! I’ve had other solar charges and it usually takes then several days of direct sunlight to fully charge. I assume this one charges so fast because it has multiple panels. It may look a little silly but it sure is practical.

    Amazing power bank with a tad over 16k mAh actual capacity. After draining it and charging it with nothing more than the solar panels, I was able to get enough charge for my phone to get 50% on about 4 hours of sun. That plus the built in flashlight make it great for emergencies such as hurricanes, general power outage, ect. Using the panels you can easily extend the usage further than the capacity if you put it in sun right after charging your phone.

    With 25,000 mAh, I can charge my devices many times before I need to charge the battery unit. As I do my out door activity, I leave the solar panel open to have my battery pack constantly charging as well. I don’t have to worry about not having enough battery.

    Purchased this in preparation for next camping trip, tested charger to make sure charger would charge my electronics. Straight out of the box charger showed 3/4 charged (3 of 4 lights lit). I plugged 2 cellphone in one 65% and the other 52% after about 3 hrs both phones almost fully charged (99% and 92%) and charger showing 2 of 4 lights lit. Charged battery charger via solar panels for an hr as test, indicator showed charger at 3 of 4 lights lit. I will update after camping trip. One problem I found was with a 7 ft cord, my phone would not charge but did work perfectly with my 5ft, 3ft, and 1ft cords.

    I got this because I go camping with my friends and this is a very good product to have. We have rechargeable lights and phones to charge and the area does not have any electricity. The power bank is light weight and charges 2 items at once. It charges a decent amount of devices and leaving it out allay in the sun charges up the unit.

    This battery is hefty, but is very easy to grip by its textured coating. I liked the folding solar panels which are kept in place by a single snap,It took me awhile to figure out that there is a fifth tiny light hole which is lined up with the other 4 dots that glow blue when the unit is charged. The fifth dot glows green( hard to see)when the battery is being charged by the sun of which takes hours to charge to 50-75%. The instructions are specific to say to not rely upon the solar panels as the main charging source. I did use it in an emergency when a neighbor’s hackberry tree limb fell upon our utility lines after midnight. I relied on this power bank to make all the necessary calls, searching the internet to gather the people and resources needed to cut the limb, repair all the lines and to fix our fence. I carried this battery around plugged into my cell phone–we had no power and did what we had to do by candle light, flashlight and by some of our solar lamps . This is not a lightweight bank of which I was glad because I was able to charge a Kindle HD 10.11 to it at the same time I had my phone plugged in..

    I tried it multiple times as a regular power bank as I use my phone a lot and I don’t want to sit near the outlet so I use powerbanks regularly. The other powerbanks I have are 10000mAh and I am happy with this one since I need to charge this one less frequently due its bigger capacity. The size of the powerbank is reasonable and relatively small (again considering its capacity). I also gets fully charged very fast for its capacity when it is connected to the outlet. The solar panel is small but it charges the powerbank well. I really like its foldable solar panel. The only concern I have is that it seems the capacity is not as much as it is advertised. My phone has 4000mAh battery and I couldn’t charge my phone even 5 times. Maybe because I was using my phone at the same time while charging and it takes more power to charge the phone to 100%. I also preferred it had Quick Charge technology (which allows higher charging voltage based on the device connected to it) but even for the 5V charging it charges my phone fast. Overall, I am happy with it and recommend it to those who want to have a descent small and high-capacity powerbank with solar-charging capability.

    I order two of these. One for myself and another as a stocking stuffer. I have a Note9 phone and today in Sonora, Ca was overcast and eventually rained. Today was the first day of use. I began using the charger with 2 full bars and one flashing on the power bank in the dash of my work truck. The battery on my phone was 70% when I plugged the charger in with all solar panels exposed. To my surprise not only did it charge my Note9 to 100% in about 20 mins it kept it 100%. It did not feed off my phone as I read in a previous review and mine also came with the micro USB cable to hard charge the unit as another said theirs did not come with a USB cable. It did take about 6 hours to fully charge the unit while still plugged into my phone but that was impressive to me considering the overcast and keeping my phone at 100% the entire time. I am already buying more to keep in our travel trailer, our cottage and for each vehicle. It does as advertised and blew my expectations away.

    I love to go camping. I always had a problem to charge my smartphone or camera. It was challenging for me because every solar charger I had before needed more than three days for full charge. This solar charger is best I ever found because it needs two days for full charge. Also flashlight is very useful.

     I use a lot of electronics out on the trail. As an aspiring outdoors youtuber, and just a video junkie overall, I love shooting video out in nature. This requires a lot of power and a lot of devices to be kept charged.My old everyday battery pack would work out for multi-day backpacking trips, but I would always be worried what if I completely ran out of juice while out on the trail? Therefor I needed a new battery pack that had to meet 3 criteria:1. Recharge via solar. More panels the better. Self-contained preferred.2. Have a large capacity for multiple devices over multiple days3. Be rouged enough to use out in the elements.After much searching on Amazon I ultimately pulled the trigger on this battery pack.This battery pack has 4 solar panels which all can independently charge the unit. In my tests it takes anywhere from 6 to 8 hours to recharge it completely from empty. That’s not bad at all given that it’s almost impossible to have the perfect charging situation. Some options out there are to have a separate panel assembly to charge your battery pack, but I don’t want to have yet another thing to lose. This all in one design worked out for me.The Capacity is plenty for me to go through with all of my filming gear, and topping it off every day during the daytime left me with no anxiety over running out of juice!Lastly, this thing has survived drops and liquid spills. I’m one happy camper when it comes to it surviving the outdoors.I hope this review and the video helps you choose a solar powered battery pack. I enjoy doing these review because it’s more practice for my filming, editing, and writing skills, and a way to pay it forward for all the other reviews on Amazon from the community that have helped me make other purchases.Thanks!
