I am looking for a multi port charger that can do at least 5v/2a for the M3. I have a number of them that are capable of 5v/2a and even QC 3.0 but the M3 will only charge at 5v/1a when I tried multiple chargers.
This is quite interesting. I have stand alone chargers but I don't know if with a multi port the M3 only charges at 5V/1A. I will try my charger and let you know.
