Independent charging channel: 4 channels can charge 1 to 4 batteries, about 3.7 hours can be filled with 1 or 4 9V batteries. Automatically power off when fully charged, it is safe and can extend battery cycle life.
Intelligent chip protection: Constant voltage charging is controlled by internal IC. Input: 5V 2A ,Output:8.7V±0.2V*4Ch 260mA±20mA*4Ch. There is no memory effect, without any damage to the battery, ensuring the battery's cycle life and capacity.
LED indicator: The red light is always on when charging, it turns to green when it is full. With USB Type-C charging cable, it is not affected by the environment and can be charged as long as there is a USB interface. It is very convenient.
Multi-Protection: Our batteries and chargers have passed ROHS, CE, CQC, PSE, etc. certification. Built-in protection device to prevent Overcharge, Overvoltage, Overcurrent, Over Discharge, Reverse Charge and Short-circuit protection, can protect the battery and charger very good.
