Power bank 2A trick

[Daniella Gutlansky]

Hi,
I have several power banks, each with different capacity.
I've noticed that when I connect my nexus to a 1A port, it says "charging (ac)",
but when I connect to the 2A port, it says "charging (usb)".
The usb charging (2A) is slower than the 1A charging.

Though I can understand why usb charging is slower than AC charging,
I don't understand why EVERY 2A charger has to be a usb charger?

Thanks in advance!

I'm not sure why this is the case - it's a little too technical for me. However, have you checked with the power bank technical specs to see if this is supposed to be the case or not?

Also, if the 1A port is charging just fine, why not keep using that?

It is not supported to be the case, according to the tech specs.
I CAN use the 1A, but then I loose the full functionality of the device. 2A should be faster, and the device should be able to charge 2 devices at a time.
