Autel Unstable Internal Power or Firmware Crash

Charger randomly reboots or restarts during charging sessions without showing an error code.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Failing low-voltage power supply, Loose low-voltage connectors, Firmware instability, Electrical noise on supply

Safety first: Turn off power before accessing internal components.

Check supply stability: Have an electrician verify that the input voltage is stable and within specification during charging.
Inspect low-voltage wiring: With power off, reseat connectors between the low-voltage power supply, main board, and communication modules.
Firmware update: Update the charger firmware via the Autel app to the latest version.
Replace power supply: If reboots persist, the internal low-voltage power supply module may be failing and should be replaced.
