    Charges my galaxy phone 100% in less than an hour. Bought this because I have 2 fast charge devices and 1 that is usb only. Haven't tried all 3 at once but probably won't need to. Takes a few hours to get a full charge on this product but understandable. Satisfied, does what it's supposed to.

    Honestly, I did not expect a screen that shows you the percentage and how much time is left! WHAT?! Anker would charge $70+ for the same thing… Impressive! Only downside is the phantom drain after a week or so is about 20-30%, but other than that, great!
