Solar Power Bank 50000mAh, Portable Solar Charger Compatible with iPhone,Tablet,Earphone, External Battery Pack with 9 LED Lights (Blue)

I paid $50 for it but it was WELL worth the money. A 50,000mAh SOLAR Power Bank with 4 USB Ports is pretty INSANE.This brick-sized Power Bank feels like it's meant for either long road trips (by car, RV, bus or train) or emergency power situations to me. Unlike smaller solar power banks, this one doesn't feel like it would be a lot of sense to use it for traveling on the go. You're definitely going to feel the weight if you try to use it that way.Fair warning, this power bank takes a a LONG time to fully charge via USB when you first get it. Do yourself the favor of fully charging it and then enjoy not having to USB charge it again probably for at least a week if you don't use it heavily but it can probably last you at least a few days if you're trying to fully charge 4 devices at the same time.This Solar Power Bank does have a built-in small LED Flashlight on the underside. To turn it on, double press the power button on the side. One it's on, press the power button to switch between two brightness evels and an SOS Strobe. That could be very handy if you're camping or live in a rural area.Overall, this is a solid purchase I strongly reccommend. Practice common sense by not leaving this in a hot car or anything like that unless you're cool with it possibly exploding. Like all Solar Power Banks, the charging speed is decided by the intensity of the sun hitting the solar panel. Like all Solar Power banks, only use the Solar Charging when USB Charging isn't immediately available because it will take a while. A workaround to that would be to hook up a separate portable Solar Panel--you can buy 'em for less than $20 on Amazon--and hook it up to this. It's not a bad idea when you think about it.

Held a charge at night, left in sun while hiking, works like supposed too

It has two ways of charging but the solar panel charging only charges half-way and not fully.

All 4 of the outputs are slower than anything. With the Original fast charging cable that came with my phone, it still said (pops up on the bottom of the screen when you plug the cord into the phone) it would take 4hrs and 28 minutes to fully charge my phone, which was only at 68%. I tried other cords and other devices and everyone came up that it would take 4 plus times longer than any other charger. I returned this it was basically unusable. Also know it is HEAVY. Not something I would choose to put in my bag for a day at an amusement park or even camping.

Great

Compact and easy to use.

This does actually charge by solar energy. It also charged my granddaughters tablet while charging my phone and we were using them while charging. It took less than an hour for both devices to fully charge while using the devices.I bought a different solar battery pack before this and it actually won't charge by solar. You have to plug into an outlet to charge it. This on the other hand does what it says. I ordered a total of 3 more now so I can have them in my truck and home and the family is covered. Worth the money and the $15 coupon just makes it even a better deal.

Still working but could be dangerous around kids or pets I guess you can’t leave a solar panel in the sun kinda weird probably not worth the money if it expands out of it’s case
