By plugging the XPower 450 inverter directly into a 12VDC cigarette lighter socket or by connecting directly to the battery, you can turn your vehicle into a mobile office or have power to run entertainment electronics like popular handheld games or TVs. In addition, the XPower 450 inverter automatically senses low battery voltage so you never have to worry about a depleted battery. Ideal for damp or humid environments, the XPower 450 is specifically engineered to provide corrosion resistance and short-circuit protection.
