It is normal for this message to appear in the following situation:
When the USB-C port and wireless charging are both providing output at the same time, the maximum USB-C output voltage is 9V. If a high-power device such as a laptop is connected to the USB-C port, the available output may not meet the device's minimum power requirement, triggering the "Circuit Protection" message.
What you can try
-
Remove all connections. Disconnect all cables and devices from the power bank, let it sit for 30 minutes, then check whether it returns to normal.
-
Inspect the ports. Check all ports for debris, dirt, or signs of liquid exposure that could interfere with the connection, and gently clean them with a soft, dry, lint-free cloth.
-
Use one output at a time. Use only the USB-C port or only wireless charging — do not use both at the same time. Test charging and discharging through each output separately.
-
Try a different cable. Use a different charging cable to rule out cable issues.
