(DC) 5V/2A plug*1, 5.5 x 2.1 mm; 5V/1A plug*1, 5.5 x 2.1 mm
(The same set of USB ports and DC plugs of 5V output cannot be connected simultaneously.The two sets share the same current output)
The maximum current gross output of two 12V ports is 3A, which means if you connect 12/3A port to a device which requires exactly 12/3A input, then the 12V/1A port cannot be used.
The maximum current gross output of two 5V ports is 2A, which means if you connect 5V/2Aport to a device which requires exactly 5V/2A input, then the 5V/1A port cannot be used.
