How do I connect the Steren 300-120 power inverter to my car?
Connect the red clamp to the positive terminal of the battery and the black clamp to the negative terminal. Ensure the vehicle is off during installation to prevent sparks. The inverter has built-in surge protection for safe operation.
What devices can I power with a 300W inverter?
