Q1: Why does it sometimes wake up my device when I plug in or unplug another device ?
A1: When multiple devices are connected at the same time, plugging a new device in or unplugging any of the devices from the charger will render a short charging pause for other devices.
This short pause is due to the power redistribution of the charger.(when you connect 4 devices, power will be distributed efficiently between both ports to ensure you get the best charge.)
Q2: How to get the best performance of all charging ports?
A2: When you need to use 3 or more of the charging ports simultaneously, to maximize the output power, it is suggested to preferentially use the C1/C2/A ports. The combination of C3 and A is not recommended because the power output would be minimal in this case.

Less Heating & Higher Efficiency
One of core factors of affecting power efficiency is the heat-dissipating capability.The third generation gallium nitride(GaN)semiconductor helps the charger to generate less heat and fasten the heat-dissipating process. At the meantime,this charger provides double power density and reduces power losses by 80% whcih also means increases the power efficiency.![](https://ae01.alicdn.com/kf/He4c3cf54b5484806a16325e7a498ba20p.jpg)
