1. Introduction
This manual provides essential information for the safe and efficient operation of your Cantonape 800W/2000W Peak Car Power Inverter. Please read it thoroughly before use and retain it for future reference. This device converts 12V DC power from your vehicle's battery into 110V/120V AC household power, suitable for various electronic devices.
2. Safety Instructions
WARNING: Failure to follow these safety instructions may result in serious injury or property damage.
- Ensure proper ventilation around the inverter. Do not block cooling vents.
- Keep the inverter away from water, moisture, and flammable materials.
- Do not open or disassemble the inverter. Refer servicing to qualified personnel.
- Connect the inverter only to a 12V DC power source. Do not connect to 24V or other voltage systems.
- Avoid using the inverter with high-power inductive loads such as refrigerators, microwaves, coffee makers, hair dryers, or curling irons, as these may exceed the inverter's capacity or require pure sine wave power.
- Always connect the positive (+) terminal of the inverter to the positive (+) terminal of the battery, and the negative (-) terminal of the inverter to the negative (-) terminal of the battery. Reverse polarity can damage the inverter and connected devices.
- When using the cigarette lighter plug, ensure the connected device's wattage is under 150W to prevent blowing the car's fuse. For higher wattage, use the battery clamps.
- Disconnect the inverter from the power source when not in use.

6. Operating Instructions
6.1 Powering AC Devices
- After connecting the inverter to your vehicle's power source (as per Setup section), ensure the inverter is ON.
- Plug your AC device (e.g., laptop charger, fan) into one of the 110V/120V AC outlets.
- Monitor the LCD display for input voltage, output voltage, and load capacity.
6.2 Charging USB Devices
- After connecting the inverter to your vehicle's power source, ensure the inverter is ON.
- Connect your USB device (e.g., smartphone, tablet) to one of the 3.1A USB ports using a compatible USB cable.
- The device should begin charging automatically.

7. Maintenance
- Keep the inverter clean and free from dust and debris. Use a dry cloth for cleaning.
- Regularly check all connections to ensure they are tight and free from corrosion.
- Store the inverter in a cool, dry place when not in use.
- Do not expose the inverter to extreme temperatures or direct sunlight for prolonged periods.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power output | Inverter switch OFF, loose connection, low battery voltage, blown fuse. | Turn ON switch, check connections, charge vehicle battery, replace inverter fuse (if applicable). |
| Overload warning | Connected device exceeds inverter's wattage. | Disconnect high-power devices. Use devices within the inverter's continuous wattage. |
| Overheat warning | Poor ventilation, prolonged high-load use. | Ensure proper ventilation, reduce load, allow inverter to cool down. |
| Device not charging via cigarette lighter | Device wattage exceeds 150W. | Use battery clamps for devices over 150W. |
