- Confirm that your device is turned on and functioning correctly.
- Check if the wall outlet is active by plugging in another known working appliance.
- Device Not Charging/Powering On:
- Double-check that your device's voltage and current requirements (e.g., 5V, 1A) match the adapter's output specifications.
- Ensure the barrel connector's outer diameter (OD: 4.8mm) and inner diameter (ID: 1.7mm) match your device's input port precisely.
- Confirm that the polarity (positive inside) is correct for your device. Incorrect polarity can damage your device.
- Adapter Overheating:
- While the adapter has overheating protection, excessive heat can indicate an issue. Ensure adequate ventilation around the adapter.
