Difference Between a Low Cost Power Inverter and the More Expensive Models

Have You ever wondered why a few inverter cost much more than others of the same power. I’ll briefly describe one of the main differences between a minimal cost power inverter and also a high price item.

Locating a power inverter to convert DC electricity to AC may seem like it should be a very simple undertaking, but if you start searching for a power inverter for your private use, you’ll soon realize that lots of choices will confront you. With costs ranging from less than $25 to well over a 1000, it can be difficult to understand what attributes are important and how to choose a unit appropriate to your needs.

While wattage you Want And how you’ll be connecting the unit to your own power supply are things to be taken into consideration, another thing that you need to take into consideration is your inverter’s wave type output. True-sine wave inverters produce power that’s either identical or sometimes marginally superior to electricity in the general utility energy grid system. The power wave when seen through an oscilloscope is a smooth sine wave. Modified-sine wave power inverters create a power wave that is adequate for most devices. The electricity wave isn’t exactly the same as power from the electricity grid. It has a wave shape that appears as a choppy squared-off wave when viewed through an oscilloscope. What exactly does that mean to the user? Not much. Most household electrical devices will operate perfectly fine on either type of wave form.

Most of our customers who are using a Power inverter to operate a laptop, a/c mobile phone charger, fan, or camera find a modified-sine wave power inverter that operates via the cigarette lighter socket that the easiest to use.

We usually suggest Choosing power inverters that are ranked under 300 watts when utilizing the 12-volt cigarette lighter socket located in most vehicles. We suggest this because after reaching 300 watts of draw on the inverter, the fuses in your vehicle will begin to blow. There are lots of units available on the marketplace powered by 100-200 watts that plug right into the cigarette lighter of a car or truck. It has just 1 socket, but since hammering it into a 12 volt socket is all that is required for operation, it can’t be beat for ease of use. These little units generally provide around 150 watts of continuous operation and usually have a built in surge protector.

Square wave components or your low cost power inverters fall in the following three classes:

500w Or less For household appliances, TVs (up to 19″), VCR, desktop computersalong with other cellular office equipment. The majority of these connect via a 12-Volt plug.

501-999w For household appliances, big screen Most such inverters are connected directly to the 12-volt battery and also have three or more grounded sockets for attaching several products in precisely the same time.


The Issue with wave form only Comes into play when specialized pieces of equipment have to get powered. Here are a few devices which could have problems when they are Connected to an inverter creating a modified-sine wave sign: oxygen Concentrators, fax machines, laser printers, high voltage cordless tool Chargers, gear with variable speed motors, electric shavers, and Garage door openers. For many all other applications you can go with the Low price power inverter.
