Pure sine wave inverter reviews and buying guide

What are pure sine wave inverters?

Pure sine wave inverters are devices that change direct current to alternating current. This means that it changes electric charge, but it does not store or produce electricity. It can be widely used to transform electricity from sources such as batteries and fuel cells to AC electricity (alternating current). They are also often used in automotive industry. This is why we will make some reviews of the best pure sine wave inverters here. A pure sine inverter produces a smooth sinusoidal AC waveform. There are also so-called modified sine inverter which are a bit cheaper. Those provide highest voltage for just a few seconds, while the pure sine inverter has a more gradual peak.


Why pure sine wave inverters?

They are preferred because most appliances and electronics these days require electricity from pure sine wave when they are plugged in the electricity. They are designed to work with them. Today the world is evolving and more and more appliances every day require true sine wave in order to work optimally. So it is not just that most appliances these days use it, even in the future it seems most of them will use it as well.

What to look for when choosing the best sine wave inverter?

As we all know, there are many different models on the market and they have different characteristics. It is essential that you know how to separate good from the rest so you know which one is the best for your particular needs. In order to know that, it is good to have a list of relevant factors which you should consider. We will discuss some of the most important factors for choosing best wave inverter below.

Watt power

Probably the most important thing when buying an inverter is the watt size. Which one do you need really depends on what you are buying it for. Two different things are generally not able to run on the same power inverter. You do not need an inverter which will have exactly the same power as you need. It is actually good if it has slightly higher watt power than you need since this will save you a lot of troubles. Here is the list of some appliances and how much watt power they need (in case you need to know)

Appliance Watts
Cell phone 50
Computer, small electronics 300
Large TV 600
Coffee maker, iron 1000
Toaster 1200
Vacuum cleaner 1500
Toaster oven 1700
Microwave oven 2000
Generator, electric  chainsaw 3000


So different appliances have different watt power.

Peak load and continuous load

There is a difference between peak load and continuous load. Peak load is the maximum load that inverter can handle, usually only for short amount of time (few seconds). Continuous load is generally advertised and it means how much it can run normally.

Feature: USB port

Many inverters come with USB port included. They are here so power inverters can charge through USB. This is generally useful for smaller watt sizes. So power inverters with larger watt sizes generally do not have USB port.


Some inverters have actual LCD display and some do not. This is usually the feature of more expensive power inverters.

Does it allow solar charging?

This is especially useful for people who want to live off the clean energy. Some people value the nature a lot and power inverter manufacturers have adapted to that and they now offer many inverters that are being charged by solar energy. It is a useful feature.

Power jump starter

This feature is especially important if you want to use it on your car and car battery. In this way in case your car stops you can have power jump starter together with the inverter with which you can start a car then.

Air compressor

Some compressors have air compressor built in. This is very useful if you have to pump your tires or some other equipment.

Overload protection

This is mostly the feature of better and more expensive inverters. In case you plugged them in too high powered device, they automatically adapt. Some power inverters could blow up in this case, so it is very important to have the protection.


Of course in the end you also have to look at the cost. Naturally with more features the price will increase. In this guide we will review some of the best pure sine power inverters. They are the best based on the price for which you are buying them.
