A power inverter converts DC power or direct current (like a 12Volt battery) to standard AC power or alternating current(like a standard wall socket at 220V), which allows you to run electrical equipment off a 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, television, video game player or DVD theater are all examples of devices that will get you through a blackout.

Where do I use a Power inverter?

In an electrical 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.

Power inverters come in many models that vary in watts. The amount of wattage you will require on yours depends on the total draw of the devices you'd like to use. If you have a two-outlet inverter and will be plugging in 2 devices at once, add up the total wattage of both devices then add at least 50% more to account for peaks or spikes in the power draw. For example if your DVD theater draws 100 watts and your laptop another 100 watts, a minimum 300-watt inverter is recommended. Power inverters operate on the assumption that the battery is in good condition and fully charged. A weak battery will be drained easily if demands are too high. This could leave you stranded so be sure to
check the battery's condition before using a power inverter in a stationary vehicle.

Advantages of Inverters

Inverters have two main advantages:
• They are silent
• They are maintenance-free
