A power inverter converts DC power or direct current to standard AC power or alternating current, which allows you to run AC electrical equipment off your vehicle’s battery for mobile applications, emergencies or simple convenience.
Power inverters are small rectangular devices that have a trailing wire with a jack that plugs directly into the cigarette lighter on the dashboard. They might also come with jumper-like cables for connecting directly to a battery. The device normally has one or two outlets for standard electrical cords. Your laptop, small-screen television, video game player or portable DVD theater are all examples of devices that will get you through a long ride, assuming you’re not the one driving!
Power inverters are great for camping at parks that do not provide electricity. The toaster, blender, and boom box can all still be used. On your boat you can plug in the digital movie camera to capture those great water-skiing videos you might have missed after the camera’s battery ran low!
In a utility outage a power inverter can be used for emergency electricity. Just run an extension cord from your car into the house, or if you have a charged spare battery you can connect the power inverter directly. Plug in a radio to tune into important alerts, run essential medical equipment, lights, or whatever else you need that falls within the inverter’s power limits.
