XILLIE 8016 10400mAh 5V Dual Portable Smart Power Bank for Apple Devices - Black

It works perfectly for me with one exception. I have it plugged into a tascam DR60D MK II (stinking long name) audio recorder (so something that just draws power), and the stupid little blue lights flash on and off every few minutes, draining the battery over a day or so. What the heck?! It's not a problem, just an inconvenience, but who thought THAT would be a neat feature?

This thing just keeps on pumping out. It even auto-senses when you plug a cable in for charging and turns itself on... unless you were just plugging in a cable and then it turns itself off after a few.

Totally useless. Would barely charge. Didn't hold charge. Let us down when we were counting on it. Could just be this unit. But obviously won't buy it again. #firstworldproblems

It was working fine, till yesterday, It lasted only 3 months, and now it doesn't charge

I've only had them for two or three month and they allredy are starting to give me recharging issues.

Great product

Seems I can only get about 8000mah out of it

Works great haven't a problem yet
