4： Power supply

This instrument is equipped with a large capacity rechargeable battery with a capacity of 10800mAh. It can be charged with an external power supply of DCl2V and 1.0A for 8 hours each time. The red light on the Baodian panel lights up during charging, and the green light lights up after charging is completed. While charging, Baodian can still function normally. After one charge, it can work normally for 8-16 hours, and the length of time depends on the usage status
