3. Setup and Installation
3.1 Package Contents
- 1 x SYNCWIRE SW-XC812 Ultra Mini Metal Car Charger
3.2 Installation in Vehicle
- Locate the 12V-24V cigarette lighter socket in your vehicle.
- Insert the SYNCWIRE SW-XC812 car charger firmly into the socket until it is securely seated. The soft blue LED indicator will illuminate, confirming power connection.
- To remove the charger, gently pull the integrated pop-up pull ring.

4. Operating Instructions
4.1 Charging Your Devices
- Once the charger is installed and the LED is illuminated, connect your device's charging cable to the appropriate port on the car charger.
- Use the USB-C (PD 45W) port for devices compatible with Power Delivery for optimal fast charging speeds.
- Use the USB-A (QC 45W) port for devices compatible with Quick Charge for optimal fast charging speeds.
- For best performance, use high-quality charging cables that support fast charging.
Important Note: While the charger offers high wattage, the actual charging speed depends on your device's capabilities and the car's power output. Most standard car 12V sockets will provide sufficient power for fast charging one device. When two devices are connected simultaneously, the total output is shared, and individual port speeds may be reduced. For example, the PD port supports Samsung 25W super fast charging.

5. Maintenance
- Keep the charger clean and dry. Use a soft, dry cloth to wipe the surface.
- Avoid exposing the charger to extreme temperatures, direct sunlight, or corrosive materials.
- Do not attempt to disassemble or modify the charger, as this will void the warranty and may cause damage.
6. Troubleshooting
- Charger not working / LED not lighting up:
- Ensure the car charger is fully inserted into the cigarette lighter socket.
- Check if the vehicle's engine is running or if the accessory power is on.
- Verify the cigarette lighter socket is functional by testing it with another device.
- Device not fast charging:
- Confirm your device and charging cable support the fast charging protocol (PD 3.0 or QC 3.0).
- If charging two devices simultaneously, fast charging speeds may be reduced for both. Try charging one device at a time.
- Ensure your device's battery is not already near full capacity, as charging speed naturally slows down as the battery fills.
- Charger feels warm:
- It is normal for the charger to become slightly warm during operation, especially during fast charging. The all-metal design aids in heat dissipation. If it becomes excessively hot, disconnect it immediately and contact support.
