1. Introduction
Thank you for choosing the SUDOKEJI Pure Sine Wave Power Inverter. This device is designed to convert 12V DC power from your vehicle battery into 220V AC household power, allowing you to operate various electronic devices on the go. It features a pure sine wave output, ensuring compatibility with sensitive electronics, and includes multiple protection features for safe and reliable operation. Please read this manual thoroughly before use to ensure proper installation and operation.
2. Safety Instructions
- Ventilation: Ensure the inverter is placed in a well-ventilated area. Do not block the cooling fan or vents.
- Moisture: Do not expose the inverter to water, rain, or excessive moisture.
- Heat: Keep the inverter away from direct sunlight, heat sources, and flammable materials.
- Connections: Always connect the inverter to a 12V DC power source. Ensure correct polarity (+ to + and - to -). Loose connections can cause overheating.
- Load Capacity: Do not exceed the inverter's continuous power rating of 1000W or peak power rating of 2000W. Overloading can damage the inverter and connected devices.
- Cigarette Lighter Limit: If using the cigarette lighter adapter, do not connect devices with a power consumption exceeding 150W to avoid blowing the vehicle's fuse. For higher power devices, use the direct battery connection cables.
- Children: Keep the inverter out of reach of children.
- Maintenance: Do not attempt to open or modify the inverter. Refer all servicing to qualified personnel.

5. Setup
Follow these steps to properly set up your power inverter:
- Preparation: Ensure your vehicle engine is off. Place the inverter on a stable, flat surface in a well-ventilated area, away from direct sunlight or heat.
- Connecting to Battery (Recommended for >150W):
- Connect the red battery cable to the positive (+) terminal of the inverter.
- Connect the black battery cable to the negative (-) terminal of the inverter.
- Connect the other end of the red cable to the positive (+) terminal of your 12V vehicle battery.
- Connect the other end of the black cable to the negative (-) terminal of your 12V vehicle battery.
- Ensure all connections are tight and secure.
- Connecting via Cigarette Lighter (For devices ≤ 150W):
- Insert the cigarette lighter adapter into the inverter's DC input terminal.
- Plug the cigarette lighter adapter into your vehicle's 12V cigarette lighter socket.
- Important: Do not connect devices requiring more than 150W when using the cigarette lighter adapter to prevent damage to your vehicle's fuse.
6. Operating Instructions
Once the inverter is properly connected, follow these steps to operate it:
- Power On: Press the power switch on the inverter. The LCD display will light up, showing the input voltage and output power.
- Connect Devices: Plug your 220V AC appliances into the AC sockets or your USB devices into the USB ports.
- Monitor: Observe the LCD display for input voltage and output power. Ensure the total power consumption of your devices does not exceed 1000W.
- Power Off: When finished, first disconnect all devices from the inverter, then press the power switch to turn off the inverter. Finally, disconnect the inverter from the 12V power source.
