We sincerely apologise for any inconvenience caused.
Please ensure the following when charging your device using AC power:
1. Reset the device
Press and hold both the Power and USB buttons simultaneously for 5 seconds. The screen will briefly turn off and then relight, displaying the remaining battery percentage — this confirms the reset has been completed.
2. Check the charging cable connection
Unplug the AC charging cable, then firmly reconnect it. Verify whether charging has resumed.
3. Check your local mains voltage
Charging may not initiate if the household supply voltage falls below 220 V, as specified in the product specifications. Have you noticed voltage instability in your area — for example, lights flickering or dimming intermittently?
4. Confirm ambient temperature
Ensure the unit is operating within its rated input temperature range: 0 °C to 40 °C.
5. Verify the AC charging indicator
Check that the AC charging icon is displayed on the screen.
If the issue persists, please share a short video showing the INPUT (W) value displayed on the screen. If an error code appears (e.g., F1, F2, or an overtemperature warning), please let us know the exact code shown.
(Kindly ensure the screen display is clearly visible in the video.)
We’ll be happy to assist you further.
