How do I charge the Amazfit GTS 3 correctly?

Connect the USB port of the charging cable to a power adapter or computer USB port, then place the watch into the charging base, ensuring the metal contacts on the back of the watch fit closely with the base. Make sure the charging base is dry before charging, and use a 1A or above power adapter. When charging starts, the watch screen will display the charging progress. Only use the charging base that comes with the watch. (Page 6)
