JRing 15A AC to DC Power Converter Instruction Manual

Introduction

The JRing 15A AC to DC Power Converter is designed to convert standard household alternating current (AC) from 110-220V to 12V direct current (DC) via a cigarette lighter outlet. This allows you to power various 12V car devices, such as tire inflators, car vacuum cleaners, car air fans, car dash cams, car massage cushions, travel coffee makers, and car refrigerators, directly from a wall outlet. The converter supports devices with a maximum power output of 180 Watts (15 Amps).

Safety Information

• Indoor Use Only: This device is intended for indoor use only. Do not expose to rain or moisture.
• Power Compatibility: Only use within specified electrical parameters. Ensure your 12V device's maximum power output is under 180 Watts (15 Amps) to prevent damage.
• Heat Dissipation: The converter features a built-in silent fan for efficient heat dissipation. Ensure adequate ventilation around the unit.
• Protection Features: The converter is designed with safety features including over-voltage, over-current, over-temperature, and short-circuit protection. In case of an issue, the device will automatically shut off.
• Cable Integrity: Regularly inspect the power cords for any signs of damage. Do not use if cables are frayed or damaged.
• Children and Pets: Keep the device out of reach of children and pets.

Maintenance

• Cleaning: Wipe the converter with a dry, soft cloth. Do not use liquid cleaners or abrasive materials.
• Storage: Store the converter in a cool, dry place when not in use. Avoid extreme temperatures.
• Ventilation: Ensure the fan vents are clear of dust and debris to maintain proper cooling.

Troubleshooting

• No Power Indicator Light:
  - Check if the AC input cord is securely plugged into both the converter and the wall outlet.
  - Ensure the wall outlet is functional by testing it with another device.
• Device Not Powering On:
  - Verify that your 12V device is correctly plugged into the converter's cigarette lighter socket.
  - Confirm that your device's power consumption does not exceed 180 Watts (15 Amps). Overloading will trigger safety shutdown.
  - Check for loose connections between the device and the converter. Some car plugs may not fit perfectly, requiring a secure push.
• Converter Feels Hot:
  - This is normal during operation, especially under heavy load. However, if it feels excessively hot, ensure the fan vents are not blocked and there is sufficient airflow around the unit.
  - If the device shuts off due to overheating, allow it to cool down before resuming use.
