1. Check the AC socket to see if there is electricity.
2. Connect the charger to the alternating current and the equipment to see if the device indicator light is on, or to see if the setting can start normally.
3. See if the indicator light of the charger is on, or check the DC plug of the charger with a multimeter to see if there is a voltage.
