How to solve the problem of USB output turning off immediately (green indicator light goes out)

The USB output of the energy storage power supply turns off immediately (the green indicator light goes out and the output is interrupted). This may be caused by the external USB device power exceeding the rated power of the USB port or an internal fault. If your power supply has the following problems, please follow the steps in this article to troubleshoot and solve the output problem.

Phenomenon: When the USB device is connected, the output is turned off and the switch indicator light goes out immediately.

Please follow the steps below to troubleshoot and resolve output issues.

Step 1: Check the energy storage power supply display

​ Press the USB button, the green indicator light will light up. Under normal conditions, the indicator light will not go out immediately; the display shows the power consumption of the USB device.

Step 2: Check the USB device's power

The power of the USB device should be within the rated power range of the USB energy storage power supply. If it is too high, the overload protection will be triggered. If the power of the device is within the rated range and the green indicator light goes out and cannot be used, it is a fault. ​
