Setup
- Verify Compatibility: Before connecting, ensure that your device (e.g., WY-708 Android Google Tablet PC) requires a DC input voltage within the adapter's range (DC12-24V) and that the DC jack size of your device matches the adapter's connector. This adapter is designed for DC to DC power conversion, not AC to DC.
- Insert into Vehicle Outlet: Firmly insert the vehicle lighter plug end of the adapter into your vehicle's 12V-24V DC power outlet (cigarette lighter socket). Ensure a secure connection.
- Connect to Device: Plug the DC barrel connector end of the adapter into the power input port of your compatible device.
- Power Indicator: The adapter features an LED interface. A lit LED indicates that the adapter is receiving power from the vehicle and is ready to supply power to your device.
Operating Instructions
Once the adapter is properly set up as described in the 'Setup' section, it will automatically begin supplying power to your connected device. No further user interaction is typically required for basic operation.
- Ensure your vehicle's ignition is in a position that provides power to the DC outlet, if applicable.
- Monitor your device's charging indicator to confirm it is receiving power.
- Disconnect the adapter from both the vehicle outlet and your device when not in use to conserve vehicle battery power and prevent unnecessary wear.
Maintenance
- Cleaning: Keep the adapter clean and free from dust and debris. Use a dry, soft cloth to wipe the exterior. Do not use liquid cleaners or immerse the adapter in water.
- Storage: When not in use, store the adapter in a cool, dry place, away from direct sunlight and extreme temperatures. Avoid tightly coiling the cable to prevent damage.
- Fuse Replacement: This adapter is designed with a replaceable fuse to prevent charging failures. If the adapter stops working and the LED indicator does not light up, the fuse may have blown. To replace the fuse, carefully unscrew the tip of the vehicle lighter plug, remove the old fuse, and insert a new fuse of the correct rating. Ensure the new fuse is securely in place before reassembling.
