    I have a Powerbank with two outputs. When I charge my Galaxy A3 (2016) the 2.1A output is extremely slow. In the options it also says "Charging (USB)". I read that my device restricts the Input to 0.5A. If I use the 1A output it works fine. But in which situations can I use the 2.1 output? I even tried the 2.1 with my Telekom Puls Tablet and in the options it says AC Charging but Ampere only show 0.4A? Is my powerbank broken or in which situations can I use the 2.1A output? Thank you very much!

    The device determines how much power it needs while charging... not the power bank (or wall charger). That said, the only time you'll ever see something charging at 2.1 amps is if the device actually requires it, and, if the power bank can actually supply it. Even if your power bank was capable of supplying 15,000 amps, your phone might still only charge at .4 amps if that's all it needs.

    Now whether or not your power bank is working correctly, I have no idea. If your device says "Charging (USB)" then it must think the power coming from the charger is limited and so it pops up that message.
