Use a USB-Type charging cable to plug into the charging port. A red light will illuminate upon successful connection. When the red light turns off, it indicates the voltage has reached 4.2V, meaning the battery is fully charged and ready for use.

Charging Time:

A basic charge of 1 hour will bring the battery to approximately 98% capacity, sufficient for normal use. To protect the battery, the charging current significantly reduces when the battery level exceeds 98%. Reaching full capacity from this point requires an additional hour. Therefore, charging from extremely low power to full capacity generally takes 2-2.5 hours.

Note:

Do not use a fast charger for charging; the device cannot be used while charging.
