Most of the time, when the electricity gets interrupted due to a heavy downpour or a severe storm or any other reason, the reliable source of it when you require it the most is the power inverter. These devices are designed to answer these power outages and pose as a reliable and economic alternate source of electricity. That is why, the inverters have enjoyed great popularity since their introduction in the market.

These devices are designed to convert direct current to alternating current. Most of them work by converting 12 Volt DC power into 110 volts AC. With the use of an inverter you can run household appliances from a car or any other DC source in areas where there is no electricity. These are available in two categories, The True Sine Wave and the Modified Sine Wave.

Of these the True sine wave inverters provide utility grade power but are expensive and can run almost anything including laser printers and fax machines. The sine wave is most suitable to operate higher-end electronic equipment which can be damaged by other inverters. On the other hand, the Modified sine waves are the most common types available today. Like its counterpart, this inverter can sufficiently run most household appliances and tools. It is more economical compared to the true sine wave inverter, but may ask for certain compromises with some loads such as microwave ovens, laser printers, clocks and cordless tool chargers.

Power inverters are widely used for large assortment of applications, from small power supplies for a computer to large industrial applications to transport bulk power. One of the most widely used applications include running television sets, microwaves and other household appliances and charging cell phones, laptops from a car cigarette lighter outlet and running tools from a 12 volt battery on jobsites where electricity is not available.

If you are looking forward to buy one, remember that most of your household electrical devices will run perfectly on both the type of wave form. Most of the users who are using a power inverter to run a laptop, a/c cell phone charger, fan, or camera agree that a modified-sine wave that operates through the cigarette lighter socket is the easiest to use. While you buy, it is suggested to choose an inverter that is rated under 300 watts when using the 12-volt cigarette lighter socket found in most vehicles. This is because after reaching 300 watts of draw on the inverter, the fuses in your car might blow off. Such power inverters are a great choice for dashboarders who would like an easy solution to run their devices. It has only one outlet, but since plugging it into a 12 volt socket is all that is required for operation. This little inverter can supply 140 watts of continuous operation and has a built-in surge protector.
