Why the smart phone charger has two set of output values?
I have this new phone charger call ProMini PS-6T. It is very good on charging performance but I just have some question for the outputs. The output for USB are 5V 2.4A x 2 + 5V 1A x 2 Or 5V 1.2A x 4 + 3V 1A x 2. What’s that mean?
That’s the maximum current outputs for each USB port.
For 5V 2.4A x 2 + 5V 1A x 2, you can charge 2 high input (2.4A) devices and two low input devices (1A) in the same time. The total is four outputs.
For 5V 1.2A x 4 + 3V 1A x 2, you can charge 4 devices of 1.2A and two low input devices (1A) in the same time. The total is six outputs. Normally many smart phone take 1A and Tables need 2.4A output.
