The design with max output of 5V / 3.1A to single use. It is so clear that you can only use one output to charge one device with max output of 5V / 3.1A. The total current of the two devices can not over 3.1A if you want to charge two devices in the same time. That is ok for you to charge a mobile phone and a tablet computer in the same time because the charging current for the mobile phone and the tablet computer is normally with 1A and 2.1A . The total will not exist 3.1A. Can you get it? |
