Power Bank, 7800mAh Apex Premium Portable Phone Charger, Compact USB Power Banks with Smart LCD screen, LED Flashlight and Fast Charge for all iPhones, iPad, Samsung Galaxy, HTC, Smart Phones, (Black)

Bought it because Smart Phones aren't great at keeping a charge. Kept finding myself either fighting to find a plug to charge my phone or simply letting it die out. Started a new job where I do a lot of field work so this really became a major problem. So far so good, has totally eliminated the worry of not keeping up a charge. It is a bit bulky, like an old pager or the size of a garage door opener. But it will keep charge for your phone and or tablet.Update 6.2017 - Wire poor quality, had to replace it. The unit itself has worked great so far!

So far this is awesome. It takes a long time charge up but once it does you can rock and roll. Plugged it into a dead phone while Videoing, it charged thePhone up at the same time, even when a second device was charged for a bit too. Seems well built (rugged). Liking the built in flash light as well.

Bought it to recharge my kindle fire. I let the Fire get down to about 25-30% and then recharge it with the power bank 7800mah apex. I can recharge it to 100% twice. It does take a few hours but I'm usually on a school bus while its charging the kindle. Then I recharge this using my kindle ac charger.

I like the design...Doesn't hold the amount of charge I thought it would. Only charge my android phone one and a half times.

This little device seems to be going a good job holding a charge and charging my devices when I need them. The style is a little clunky but I've had no issues with the performance.

Seems to work well. Looks good. Nice size. Price ok. I like it.

Gives a good cell phone emergency charge. Charges a bit slow with the USB. Would be better to get an AC adapter. Very sturdy and very well made.

Thanks
