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.

11. Warranty and Support
