4. Setup Instructions

The BYGD 300W Car Power Inverter offers two connection methods:

4.1. Cigarette Lighter Connection (Up to 150W)

  1. Ensure the inverter's ON/OFF switch is in the "OFF" position.
  2. Insert the cigarette lighter plug cable firmly into the inverter's DC input port.
  3. Plug the other end of the cigarette lighter cable into your vehicle's 12V cigarette lighter socket.
  4. Proceed to Section 5: Operating Instructions.

Note: This connection method is suitable for devices consuming up to 150W. For higher power devices, use the battery clamp connection.

4.2. Battery Clamp Connection (Up to 300W)

  1. Ensure the inverter's ON/OFF switch is in the "OFF" position.
  2. Connect the red alligator clip to the inverter's positive (+) terminal and the black alligator clip to the negative (-) terminal. Ensure connections are secure.
  3. Connect the red alligator clip to the positive (+) terminal of your vehicle's 12V battery.
  4. Connect the black alligator clip to the negative (-) terminal of your vehicle's 12V battery.
  5. Proceed to Section 5: Operating Instructions.

Caution: Always connect the inverter to the battery before turning it on. Ensure correct polarity (red to positive, black to negative) to prevent damage.

5. Operating Instructions

  1. After connecting the inverter to the 12V DC power source (cigarette lighter or battery), press the "ON/OFF" switch on the inverter to the "ON" position.
  2. The green "POWER" indicator light will illuminate, indicating the inverter is operational.
  3. Plug your AC devices into the 110V AC outlets or your USB devices into the USB charging ports.
  4. Ensure the total power consumption of all connected devices does not exceed 300W.
  5. When finished, turn the inverter's "ON/OFF" switch to the "OFF" position and disconnect it from the power source.

Important: Some devices, especially those with motors or heating elements, may have a higher startup (peak) wattage than their continuous wattage. Ensure the device's peak wattage does not exceed the inverter's 600W peak capacity.
