6. Setup and Installation
- Select the Correct Plug: Ensure you have the correct plug specification (US, EU, or UK) for your region.
- Plug into Wall Outlet: Insert the charger firmly into a standard AC wall outlet (100-240V).
- Connect Charging Cable: Connect a compatible USB-A or USB-C charging cable (not included) to the desired port on the charger.
- Connect to Device: Connect the other end of the charging cable to your smartphone, tablet, or other compatible device.

7. Operating Instructions
Once properly set up, the Essager PD 20W GaN Charger operates automatically:
- Single Device Charging: Connect your device to either the USB-A or USB-C port using a compatible cable. The charger will automatically detect your device and deliver the optimal charging speed up to 20W.
- Dual Device Charging: You can charge two devices simultaneously by connecting one to the USB-A port and another to the USB-C port. The total output will be shared (5V/3A Max).
- Fast Charging: For devices that support fast charging protocols (PD, QC, etc.), the charger will deliver rapid power. For example, it can charge an iPhone 14 to 60% in approximately 30 minutes.

8. Troubleshooting
- Device not charging:
- Ensure the charger is securely plugged into a live wall outlet.
- Try a different charging cable.
- Test with a different device to rule out device-specific issues.
- Ensure your device is compatible with the charger's output specifications.
- Slow charging:
- Verify that your device and cable support fast charging protocols (e.g., Power Delivery for USB-C).
- If charging two devices simultaneously, the power output is shared, which may result in slower charging for each device compared to single-device charging.
- Ensure the cable is not damaged or of poor quality.
- Charger feels warm:
- It is normal for the charger to become slightly warm during operation, especially during fast charging.
- If it becomes excessively hot or emits smoke/odor, immediately unplug it and discontinue use. The intelligent IC chip provides constant temperature control to prevent overheating.
- Charger automatically powers off:
- The charger has an internal load detection chip that will automatically power off in case of overload to protect connected devices and the charger itself. Unplug devices, wait a moment, and try again.
9. Maintenance and Care
- Cleaning: Disconnect the charger from the power outlet before cleaning. Use a soft, dry cloth to wipe the surface. Do not use liquid cleaners or aerosols.
- Storage: Store the charger in a cool, dry place away from direct sunlight and moisture when not in use.
- Handling: Avoid harsh impacts or dropping the charger. Do not pull on the cable to unplug it from the wall or device.
10. User Tips
- Optimal Fast Charging: For the fastest charging speeds, use high-quality USB-C to USB-C cables for Power Delivery (PD) compatible devices, and ensure your device supports the specific fast charging protocol.
- Travel Companion: Its compact size and multi-plug options (US, EU, UK) make it an excellent travel charger. Consider purchasing the appropriate plug type for your travel destinations.
- Check Device Compatibility: While the charger supports many protocols, always check your device's charging requirements to ensure full compatibility and optimal performance.
