- Positive Terminal (Red): Connects to the positive (+) terminal of the 12V DC power source.
- Negative Terminal (Black): Connects to the negative (-) terminal of the 12V DC power source.
- AC Outlets (x2): For connecting 110V AC devices.
- PD 65W USB-C Port: For fast charging compatible USB-C devices.
- QC 18W USB-A Port: For fast charging compatible USB-A devices.
- Cigarette Lighter Plug: For connecting to a vehicle's 12V cigarette lighter socket.
- Battery Clamps: For direct connection to a 12V battery.
3. Setup and Connection
The inverter offers two connection methods: via the cigarette lighter socket or directly to a 12V battery.
3.1 Connecting via Cigarette Lighter Socket (Max 150W)
- Ensure the inverter's power switch is in the OFF position.
- Insert the cigarette lighter plug cable firmly into your vehicle's 12V cigarette lighter socket.
- Connect the other end of the cigarette lighter plug cable to the inverter's DC input terminals, ensuring correct polarity (red to positive, black to negative).
- Turn on the inverter by flipping the power switch to ON. The indicator light will illuminate.
- Connect your devices to the AC outlets or USB ports.
Note: Most vehicle cigarette lighter sockets are rated for a maximum of 150W. Do not attempt to draw more than 150W when using this connection method to avoid blowing your vehicle's fuse. For higher power devices, use the battery clamp connection.

3.2 Connecting via Battery Clamps (Full 600W)
- Ensure the inverter's power switch is in the OFF position.
- Connect the red battery clamp cable to the inverter's red (positive) terminal.
- Connect the black battery clamp cable to the inverter's black (negative) terminal.
- Connect the red battery clamp to the positive (+) terminal of your 12V battery.
- Connect the black battery clamp to the negative (-) terminal of your 12V battery.
- Ensure all connections are secure and tight.
- Turn on the inverter by flipping the power switch to ON. The indicator light will illuminate.
- Connect your devices to the AC outlets or USB ports.
Caution: Always connect the battery clamps to the inverter first, then to the battery. When disconnecting, remove the battery clamps from the battery first, then from the inverter. Incorrect polarity can damage the inverter and battery.

4. Operating Instructions
4.1 Powering AC Devices
- Ensure the inverter is properly connected to a 12V DC power source and turned ON.
- Plug your 110V AC device into one of the inverter's AC outlets.
- Turn on your AC device.
- Monitor the inverter for any warning indicators or unusual operation.
- When finished, turn off your AC device, then turn off the inverter.
Important: The total continuous power draw of all connected AC devices must not exceed 600W. For devices with high startup (surge) power, ensure their peak power requirement does not exceed 1200W.
4.2 Charging USB Devices
- Ensure the inverter is properly connected to a 12V DC power source and turned ON.
- For USB-C devices, use a compatible USB-C to USB-C cable and plug it into the PD 65W USB-C port.
- For USB-A devices, use a compatible USB-A cable and plug it into the QC 18W USB-A port.
- The inverter will automatically detect the device and begin charging.
- When charging is complete, disconnect your USB device.
