When the indicator rapidly flickers, it's time to charge the device. Use the adapter with an output of 5V 1A or 5V 2A.
Note:
- In the powered-off mode, the indicator will consistently turn red during recharging and will switch to green after reaching a full charge.
- In the power-on mode, the indicator will rapidly flicker three times to signal the initiation of charging after plugging in the USB cable. Subsequently, the light will revert to indicating its regular working status.
- If using the device while charging, ensure the use of a 5V 2A power adapter for optimal performance.
