Setup and Installation
Follow these steps for proper installation of your Qidoe 66W 12V USB Outlet:
- Drill a Hole: Choose a suitable location for installation. Drill a hole with a 3cm (1.18 inch) diameter. Ensure there is enough space behind the mounting surface for the charger's body and wiring.
- Insert and Secure: Insert the USB outlet into the drilled hole. Secure it tightly using the provided mounting nut on the backside.
- Connect Wiring: Connect the red wire (positive) to your vehicle's positive battery terminal or an appropriate fused 12V/24V power source. Connect the black wire (negative) to the vehicle's negative battery terminal or a suitable ground point. Ensure the 10A fuse is properly installed in the red wire's fuse holder.
- Verify Installation: Once wired, the voltmeter display should illuminate, indicating successful installation.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not powering on / No voltmeter display | Incorrect wiring, blown fuse, insufficient power supply. | Check wiring polarity. Replace the 10A fuse. Ensure battery voltage is within 12V-24V. |
| Slow charging or no charging | Incompatible cable, device not supporting fast charge, device fully charged, or multiple high-power devices connected. | Use a high-quality, compatible charging cable. Verify device supports PD/QC3.0. The chip stops charging automatically when fully charged. |
| Voltmeter displays abnormal voltage (e.g., 11.6V or 14.9V) | Vehicle battery voltage is too low or too high. | This indicates the actual battery voltage. If consistently too low, check your vehicle's battery. If too high, consult a vehicle technician. Normal range is typically 12V-14.5V. |
