The LCD Battery Capacity Circle indicates the remaining capacity. The circle has been divided into 6 equal segments, accounting for about17%~35%~51%~68%~85%~100%. When discharging, the blue segments of the circle will disappear to the real-time remaining capacity. When recharging, the blue circle will be flashed clockwise along the trajectory, and the digital number on the right of the circle will show you the real-time input charging power. After full charge, the whole blue circle will light up and remain stable. When charging is complete, please unplug the adapter.
