Input and output ports

If you have two or more devices, it is best to choose a mobile power supply with two output ports.

Usually one is 1A and the other is 1.5A or 2A, depending on capacity. If you plug in your mobile power and watch a video or play a game, the charging speed won’t even catch up with your power consumption, which would be very bad.
