1. Product Overview
The RoyPow AC to DC Converter (Model C180) is a versatile power supply designed to convert standard 100V~120V AC household current to 12V DC power, enabling the use of most automotive electronic devices at home without requiring a car battery. This converter provides a reliable and convenient solution for powering various 12V car accessories.
Key features include:
- Emulates Automotive Batteries: Allows powering devices with 11V/12V/13V/14V input voltage, mimicking car battery output at engine-unstart state.
- Wide Compatibility: 180W (Max 200W) output suitable for almost all 12V automotive electronics, such as air compressors, coffee makers, car refrigerators, and more.
- Quiet and Low-Heat Operation: Features a built-in silent fan for efficient heat dissipation, ensuring quiet and cool performance.
- Multiple Safety Protections: CE, FCC, and RoHS approved, with integrated protections against overcharging, short circuits, overpower, overcurrent, overheating, over-discharge, and overvoltage.

2. Setup Guide
Follow these steps to properly set up your RoyPow AC to DC Converter:
- Unpack the Converter: Carefully remove the RoyPow C180 AC to DC Adapter set from its packaging. Ensure all components listed in the "What you'll get" section are present: the power supply adapter, welcome guide, and warranty card.
- Connect to AC Power: Insert the AC input plug of the converter into a standard 100V~120V household electrical outlet. The green indicator light on the converter should illuminate, indicating it is receiving power.
- Connect Your 12V Device: Plug your 12V automotive electronic device (e.g., car refrigerator, tire inflator, car vacuum cleaner) into the 12V car cigarette lighter socket output of the converter. Ensure the connection is firm and secure.
- Placement: Place the converter on a stable, flat surface with adequate ventilation. Avoid covering the ventilation grilles to prevent overheating. The built-in silent fan requires clear airflow for optimal performance.


3. Operating Instructions
The RoyPow AC to DC Converter is designed for straightforward operation. Once properly set up, it provides stable 12V DC power for your devices.
3.1 Powering Your Device
After connecting the converter to an AC outlet and your 12V device to the converter's output socket, simply turn on your 12V device. The converter will automatically supply the necessary power. It is capable of delivering up to 180W (Max 200W) and 15A, making it suitable for a wide range of high-power automotive electronics.

3.2 Important Considerations
- Power Rating: Ensure that the power consumption of your 12V device does not exceed the converter's maximum output of 200W.
- Ventilation: Always ensure the converter is placed in a well-ventilated area and its grilles are not blocked. If operating a high-power device for an extended period, allow the converter to cool down periodically. The built-in fan should manage normal heat.
- Stable Voltage: The converter is designed to emulate automotive battery voltage, providing stable 11V/12V/13V/14V output as needed by your device.


4. Maintenance
Proper maintenance ensures the longevity and optimal performance of your RoyPow AC to DC Converter.
- Cleaning: Regularly wipe the exterior of the converter with a soft, dry cloth to remove dust and debris. Do not use liquid cleaners or abrasive materials. Ensure the ventilation grilles are clear of obstructions.
- Storage: When not in use, store the converter in a cool, dry place away from direct sunlight, moisture, and extreme temperatures. Disconnect it from both the AC outlet and any connected devices before storing.
- Cable Care: Avoid sharp bends or kinks in the power cables. Do not place heavy objects on the cables, as this can damage the internal wiring.
5. Troubleshooting
If you encounter issues with your RoyPow AC to DC Converter, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Converter not powering on (no green light) | No AC power; loose connection; faulty outlet. | Check if the AC outlet is working by plugging in another device. Ensure the AC plug is fully inserted into the outlet and the converter. |
| Device not receiving power from converter | 12V device not properly connected; device power consumption too high; converter in protection mode. | Ensure the 12V device is securely plugged into the converter's socket. Verify the device's wattage does not exceed 200W. Disconnect and reconnect the converter to reset any protection modes. |
| Converter feels hot | Insufficient ventilation; prolonged high-load operation. | Ensure the converter is placed in a well-ventilated area and its grilles are not blocked. If operating a high-power device for an extended period, allow the converter to cool down periodically. The built-in fan should manage normal heat. |
| Unusual noises from converter | Fan obstruction; internal issue. | Check for any obstructions near the fan. If the noise persists or is excessive, discontinue use and contact customer support. |
The RoyPow AC to DC Converter is equipped with multiple safety protections including protection against Over Charging, Short Circuits, Over Powering, Over Current, Overheating, Over Discharge, and Over Voltage. If the converter enters a protection mode, disconnect it from the power source and the device, wait a few minutes, and then reconnect.
