A power inverter converts DC power into conventional AC power which can run all kinds of household products such as: kitchen appliances, microwaves, power tools, TVs, radios, computers and more. All you have to do is to connect the inverter to a battery, then plug your AC devices into the inverter and you've got power on the go.

These Power Inverters are great for camping at parks that do not provide electricity for it lessens your tasks.

It is important to realize and to understand that, an inverter...modified or true sine, is only as good as your battery banks’ ability to supply the energy required.

Literally, 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 . When using a power inverter you must know what type of Power Inverter is suit for your desired appliances.

Power inverters produce one of three different types of wave output:

Square Wave power Inverters

Square wave inverters result in uneven power delivery that is not efficient for running most devices. These inverters were the first types of inverters made and are obsolete. This is also the least expensive and least desirable type. Don't even consider one of these types of power inverters for a home system.

A typical Square wave inverter will have the output voltage varying as much as the battery voltage varies. This is not good for appliances.

Modified Sine Wave Power Inverters

Modified-sine wave and square wave inverters are the most popular and the most common types of power inverters on the market. Modified square wave (modified sine wave) inverters deliver power that is consistent and efficient enough to run most devices fine.
Most appliances will run on these and purchasing one won’t drain your wallet.
Modified-sine wave power inverters produce a power wave that is sufficient for most devices. The power wave is not exactly the same as electricity from the power grid but this type of inverter delivers power that is consistent and efficient enough to run most devices such as:

Cellular phone chargers
Laptops
Computers
Some fluorescent lights
Most DIY tools, like drills and jigsaws
Small fridges
Hairdryers and electric shavers.

However, some appliances that utilizes motor speed controls or utilizing timers may not work quite properly with a Modified Sine Wave inverter. Modified Sine Wave power inverters were only recommended for smaller installations such as a camping cabin.

Pure Sine Wave Power Inverters

Pure Sine Wave (True sine wave) Inverters delivers the most consistent wave output. This type of power inverter produces the closest to a pure sine wave of all power inverters and in many cases produces cleaner power than the utility company itself. It will run practically in any type of AC equipment.

Pure sine wave inverters are the most expensive, but they also deliver the most consistent wave output. Some sensitive equipment requires a sine wave, like certain medical equipment and variable speed or rechargeable tools like oxygen concentrators, fax machines, laser printers, high voltage cordless tool chargers, variable speed motors, electric razors, and garage door openers.

Pure Sine Wave inverters produce the most reliable and consistent power wave signal. This makes them the most expensive to acquire. Some equipment are sensitive and require Pure Sine Wave inverters.

So always use a power inverter that is rated high enough for the device(s) you are running and avoid adapters that would allow more outlets than the unit is designed to accommodate.
