In general, the charging time of a GPW mouse depends on its battery capacity as well as the power of the charging device. The GPW mouse's charging input power is 5V, charging current is 500mA, and battery capacity is 240mAh. Therefore, assuming a standard 5V\/500mA charging device, the charging time is about 0.5 hours. When the charging indicator becomes steady on, it means that the charging is complete. However, the actual charging time can also be affected by the use environment, charging device and charging cable, and it is recommended to keep an eye on the charging status at all times during use to avoid overcharging.
