GOODaaaPower Bank Wireless Charger 36800mAh Solar Charger with Five Solar Panels Built-in Four Cable Five Outputs Portable Power Bank for Cell Phone with Dual Flashlights, Carabiner

Hello from South Florida!It took all day to be fully charged by the sun which I expected it. However, I had recharged two phones which we deliberately let the phones power down to 5%. Didn't take long to recharge both phones. Amazing! We are being a little bit more prepared then last time when we were hit with hurricane Milton. This is day 5 and the solar panel charger is still full power and we haven't taken it outside yet. We are going to do it again to see if it can go round two without having to take it outside. Very light, very useful, and price is awesome. We better get another one in case they want to hike up the price...lol

My cell phone has never used commercial power. I put this in the window with good sunlight and plug my cell in for charging on this every night. It works great, holds a charge when needed. But even on the road I can put it on the dash for recharging my tablet, phone, rechargeable flashlight etc. A small impact on our environment, but rewarding doing anything green like this.

Seems to function as advertised. Charging the power pack by solar takes FOREVER! Does charge phone relatively quickly though.

This would be best used as a short term backup for your cell phone or any other small electronics you may own.Charging the power bank: I received this power bank with about 1 -2 bars charged. It took hours to fully charge with a wall outlet. Using the solar panels is a slow process. It took approximately 8 -10 hours to charge from 3 to 4 bars. Charging times may vary depending on how sunny it is outside (it can also be used indoors).Charging electronics: Works very well. It was used to constantly charge cell phones. Also used it on a rechargeable radio.Durability: The power bank is sturdy. The solar panels are not flimsy and are durable for daily use.Overall I think this is a good product.

This is the 2nd solar power bank I purchased for emergency power supply while in remote wilderness.In the 1st picture, you can see both side by side. The one on the right, which only has one built-in solar panel, is the 1st one I got, with the hope to use it as an emergency power supply for phones and other devices. However, it didn't work so well with its small solar panel, and it would take days to really charge the power bank to provide enough juicy to really charge a phone.As a comparison, this GOODaaa Solar Power Bank comes with 5 solar panels which really works. Just placed it under the sun for one day, the power bank has been charged to roughly 20%, which is more than enough to charge a dead phone.Besides of the practical core function of charging by sun and storing power with its big capacity, this power bank is very convenient to use, too. I really love the built-in charge cables including type c, apple, and micro usb. So no more searching for the cables while in wilderness.This power bank also comes with a carabiner. At the beginning, I couldn't figure out how to use it, since the user manual didn't mention it at all, and also I couldn't find an obvious hole. Eventually I found this hidden built-in loop, as sown in the 3rd and 4th picture. Such a smart design but a dummy manual.The power bank is still new and it's too earlier to tell its long term qualify. However, the product page does mention 3 year replacement promise. I did contact the seller for the copy of user manual, and got the response within 12 hours.With all those good features, I found one drawback is its weight. It's a little bit at the heavy side. I'd prefer lighter weight, even with the cost of smaller capacity. Every oz counts when you have to put all the weight on your shoulder.Overall, this GOODaaa Solar Power Bank is a better replacement power bank with solar charging for my purpose.

This unit is a beast. I initially charged ot via wall USB C plug to.full capacity. I was able to get five charges with no problem of my cell phone from around the 20 percent to 100 percent. I charged it in the sun and it filled the power cell fairly quickly as it sat during daylight hours. Good buy and fits in small pouch on my back pack. Plus it has its own built in lighting.

They worked well

this reserve battery packs a punch it really can come in handy during power outages i learned this when i had no power for 4 days during the CA wildfires
