Maintenance
- Keep the charger clean and dry.
- Avoid exposing the charger to extreme temperatures or humidity.
- Do not attempt to disassemble or repair the charger yourself.
- Ensure the foldable prongs are fully extended when plugging into an outlet and fully retracted when storing to prevent damage.
Troubleshooting
- Device not charging:
- Ensure the charger is securely plugged into a working wall outlet.
- Verify that the charging cable is properly connected to both the charger and your device.
- Try using a different charging cable or device to rule out cable or device issues.
- Slow charging:
- Confirm your device supports fast charging and that you are using a compatible fast-charging cable.
- If charging two devices, the power output is split (27W and 20W). For maximum speed on a single device, ensure only one port is in use.
- Ensure your device's battery is not near full, as charging speed naturally slows down as the battery approaches 100%.
- Charger getting warm:
- It is normal for the charger to become warm during operation, especially during high-speed charging.
- If the charger becomes excessively hot or emits smoke/odor, immediately unplug it and discontinue use. Contact customer support.
