Features: DC 5V1A power supply, the input interface is a standard TYPE-C port, and it is also equipped with a USB to TYPE-C cable and a Ni- battery pack + two battery covers, which is very convenient to use. The built-in circuit has overcurrent protection for input current, short circuit protection for output, and overvoltage and reverse polarity protection for battery charging. This product uses a dedicated Ni- battery charging management IC design. When charging, when the Ni- battery voltage reaches 2.85V, it will automatically stop charging, which can effectively1protect the handle and the Ni- battery pack. It also has over-voltage protection, Over-current protection, output short-circuit protection and reverse polarity protection. When charging, you can directly know the charging status of the battery pack on the handle from the light-emitting color of the two handle patterns on the front display panel, which is very intuitive. When the input power is sufficient 5V 1A, the maximum charging current of a single handle can reach 300 mA ~ 320mA. When two handles are at the same time, the maximum charging current can be guaranteed to be 250mA ~ 300mA.
