Understanding the OBD2 to Cigarette Lighter Female Adapter
An OBD2 to cigarette lighter female adapter is a simple device that allows you to power your OBD2 scanner directly from your vehicle’s 12V cigarette lighter outlet. This is particularly useful when the vehicle’s OBD2 port doesn’t provide sufficient power, a common issue in older cars. The adapter essentially converts the cigarette lighter’s power output into a format compatible with your OBD2 scanner. This ensures a stable power supply, allowing for accurate diagnostics without draining the car’s battery. male obd2 port to 12v outlet
