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 DC12V 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 a single charge, it can work normally for 8-16 hours, depending on its usage status.
