I plugged in my phone that was at 5% and I only got about 56% charge from the whole charging pack.

The unit I received is defective. I tried to charge it for 8 hours and only one light lights up. I have no idea if the Power Bank is fully charged or is only 25% charged. If all power banks are like this, I can't recommend it's purchase.

It worked fine at first but it stopped charging my devices after a month. Would not recommend.
