Generally speaking, electrical appliances can't continue to work when unplugged, but the driver will still work when unplugged. There is a lithium battery in the driving recorder to store power, and it can continue to work for several hours when the external power supply is unplugged. When the internal battery is almost dead, there will be a reminder to connect the charger, but it is generally not recommended to unplug the external power supply, because the internal battery is generally used for emergency, so try to use the external power supply to record what happens at any time. I hope I can help you.
