6. Operating Instructions
6.1. Charging Devices
- Cigarette Lighter Sockets: Plug in your 12V/24V car appliances (e.g., dash cam, GPS, car humidifier, car fan) into any of the three sockets. Ensure the individual switch for that socket is turned ON.
- USB Ports: Connect your smartphones, tablets, or other USB-powered devices to the USB ports. The Quick Charge 3.0 port (often red or specially marked) provides faster charging for compatible devices.
6.2. Monitoring Battery Voltage
The LED voltmeter continuously displays your vehicle's battery voltage. This helps you monitor the battery's health and prevent excessive discharge.
- Normal Range (Engine Off): Typically between 12.0V - 12.8V.
- Normal Range (Engine On): Typically between 13.5V - 14.7V.
- Low Voltage Warning: If the display shows below 10.5V, your car battery may be low and require attention.
- High Voltage Warning: If the display shows above 14.6V (or 28V for 24V systems), there might be an issue with your vehicle's charging system.

8. Troubleshooting
- Device not powering on:
- Ensure the car charger plug is fully inserted into the vehicle's socket.
- Check if the vehicle's ignition is on.
- Verify the main power switch on the splitter is ON.
- Check the fuse in the car charger plug and replace if blown (refer to Section 7.2).
- Confirm your vehicle's battery voltage is within the normal operating range (above 10.5V).
- Individual socket not working:
- Ensure the individual ON/OFF button for that specific socket is pressed and its blue LED is illuminated.
- Check the power consumption of the connected device; it should not exceed 100W for a single socket.
- Slow USB charging:
- Ensure your device supports Quick Charge 3.0 if using the QC 3.0 port.
- Use a high-quality USB cable.
- Reduce the number of devices charging simultaneously if experiencing significant slowdowns.
- Automatic power cut-off:
- This is a safety feature. If the total power output exceeds 180W or a single socket exceeds 100W, the device will automatically cut power to prevent damage. Unplug some devices and restart the unit.
