The USB charger suddenly stops working while charging the RC car, which may be caused by the overload protection mechanism of the charger triggering or power supply failure.
The charger usually has an overload protection function, which automatically cuts off the power to protect the device and battery when the charging current is too high or the voltage is abnormal.
In addition, if there is a fault in the charger’s power line or internal components, it may also lead to a sudden stoppage of operation.
