Falut symptom: INPUT has no power
Troubleshooting steps:
① Please ensure that the charger complies with the USB PD (fast charging) protocol. Incompatibility of the protocol will result in no charging.
② Check whether the connection between the charger, cable and the device is secure.
③ Make sure the ambient temperature is between 0℃ and 45℃ (excessive heat or cold will trigger protection, and the device can be restored after the temperature is normal).
④ If the SOC (remaining battery level) is 100% and cannot be charged, it is a normal overcharge protection.
⑤ If the screen displays a fault code, please follow the troubleshooting steps for the fault code.
