Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger display is off / not powering on. | No power supply or faulty cable/adapter. | Ensure the USB cable is securely connected to both the charger and a working USB power source. Try a different USB cable or power adapter. |
| "Err" displayed on screen. | Battery inserted with reverse polarity or short-circuited battery. | Remove the battery and re-insert it with correct polarity. If "Err" persists, the battery may be faulty or short-circuited. |
| Battery not charging. | Battery is fully charged, faulty, or incompatible. | Check the display for "Full" indication. Ensure the battery type is compatible with the charger. Try another known good battery. |
| USB output not charging external device. | Insufficient battery power in charger, or external device cable issue. | Ensure the Li-ion battery in the charger is sufficiently charged. Try a different USB cable for the external device. |
