20000mAh Solar Power Bank Solar Charger Waterproof Portable Battery Charger with Compass for iPad iPhone Android Cellphones (Green)

Battery life is excellent, but it does take a long time to recharge itself (off ac) it's been too cloudy to charge by the solar function. My bright tactical flashlight will charge it, but wow that would get expensive. But was impressed that it responded to it though. Excellent value. Charged my phone with battery life to spare. Probably will charge it 6-7 times on a single charge. My tablet 3-4 times.

I really like that it can charge more then one thing at a time. The most important thing is to charge it fully by the outlet the first few times before relying solely on the sun. I’ve used it by the pool, in the car. I always bring it when I travel because I don’t always have access to an outlet. I like as a bonus that it has a great flashlight. I’ve had it for about 6 months or so and have used it a lot. I have recommended it to several people.

Alright, let's start with this thing only cost $20. US. Here is my honest review. I purchased this to take with my on my vacation to the Philippines. I charged it via usb right ot of the box. It held its charge and worked great when i needed it. Charged by Samsung s8 with no problems. Didn't think i needed the flashlight but it did come in handy on occasion. It was charging itself everytime i took it outside. I don't know how long that would take but at least it can. Seems well built, held up well to all the traveling I did. For all that have put negative reviews on here, i don't know if they got a bad one or they are just complaining to be complaining. It cost 20 bucks so i didn't expect it to work like a store bought $80 unit but it did.

This would not charge and did not work. I plugged it in to charge and left it over night, light was still flashing when I unplugged, and tried to charge my phone with it. My phone went from 12% to 14% and the Power Bank was out of power. I plugged it in again and 2 hours later, heard a popping noise, the back cover exploded off. I would not recommend this to anyone.

I charged the device before leaving on the road trip. Often a couple of uses we then left it in the sun on top of the beach tent to recharge it seems to take a while for it to recharge to the full energy level. I will try once more before sending it back.

Excellent for traveling! We used it for a road trip and at the beach for iPads and phones. Lasted long and even charged as it was charging my phone at the beach. I just bought another one for my other kid.

This is the swiss army knife of batteries.Can be charged on the wall or via solar panel. The compass is a nice addition and the clip is perfect to hang it in my back pack while hiking or at the beach. It's also way lighter than my other backup battery of 20K.
