Installation Guide
Safety Precautions
- Always disconnect the vehicle's battery before beginning any electrical installation.
- Ensure the installation location is dry and free from obstructions.
- Use appropriate tools and wear safety glasses.
- If you are unsure about any step, consult a qualified professional.
Mounting Instructions
- Choose a suitable flat surface in your vehicle (car, boat, RV, etc.) for mounting the charger socket. Ensure there is enough space behind the mounting surface for the body of the charger and wiring.
- Drill a hole of appropriate diameter (refer to the dimensions in the Specifications section, typically around 1.13 inches or 29mm) at the chosen location.
- Insert the USB charger socket into the drilled hole. Secure it by tightening the threaded retaining nut on the back of the socket until it is snug. Do not overtighten.
Wiring Instructions
- Identify the positive (+) and negative (-) terminals on the back of the USB charger socket. The positive terminal is typically marked with a '+' symbol, and the negative with a '-' symbol.
- Connect the red wire (positive) from the included 3.3 ft wire to the positive terminal of the charger socket. Use the provided insulated terminals for a secure connection.
- Connect the black wire (negative) from the included 3.3 ft wire to the negative terminal of the charger socket.
- Connect the other end of the red wire (positive) to a fused 12V/24V power source in your vehicle. The included 10A inline fuse should be installed on this positive line, close to the power source, to protect the circuit.
- Connect the other end of the black wire (negative) to a suitable ground point on the vehicle chassis or directly to the negative terminal of the vehicle's battery.
- Once all connections are secure, reconnect the vehicle's battery.

Maintenance
- Cleaning: Periodically wipe the exterior of the charger socket with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Waterproof Cap: Always ensure the waterproof cap is securely closed when the charger is not in use, especially in wet or dusty environments, to maintain its IP65 rating.
- Connections: Periodically check all wiring connections to ensure they remain secure and free from corrosion.
- Fuse Replacement: If the charger stops working, check the 10A inline fuse. If it is blown, replace it with a fuse of the same rating (10A).
