Generators have numerous uses; they are great for homes, camps, RVs, concerts, and just about every situation where electrical power is needed. However, standard generators tend to be huge and exceptionally heavy, not to mention noisy as hell and hazardous to the environment.

Their usability is undeniable, but so are their shortcomings. If you’ve had the displeasure of using fuel-powered generators in the past and are looking for an upgrade, we warmly suggest that you stick around as we review the Top 5 Best Inverter Generator models in 2021.

What is an Inverter Generator?

An inverter generator operates on batteries as opposed to running on fuel, which is both more cost-effective and eco-friendly at the same time.

Many inverter generators also use fuel, but that fuel is converted to power for the batteries and then used from there. The benefit of this is that the power can be used as needed and the generator output does not need to be full power. This is ultimately what makes these generators more efficient.

Why should I buy inverter generators?

Let’s be frank – inverter generators aren’t down-scaled super-charged versions of traditional fuel-powered generators, but they are superior in more ways than one.

First and foremost,  You may not have to worry about buying or storing fuel. Some inverters are hybrids in the sense that they work on both fuel and electricity (simultaneously or alternatively, depending on the model in question).

Secondly, inverter generators are substantially quieter. The use of fuel can make quite a bit of noise as the generator processes it while inverter generators hum.

While we’re on the same note, we should mention that fuel-powered generators, as well as their petite portable generator counterparts, bring their own benefits to the table. Inverter generators are simply better-rounded and a bit easier to use and maintain in the long run. In that light, let’s take a look at some of the best inverter generators on the market.

Best Overall Generator – Briggs & Stratton P2200 Power Smart Series 2,200 Watts Inverter Generator

If you are looking for a powerful, compact, low-noise generator, we warmly recommend Briggs & Stratton’s P2200. Even though it’s not the cheapest of the bunch, it’s certainly one of the most versatile options within its price range.

In a nutshell, this is a 2200-watt capacity inverter generator that weighs approximately 55 pounds. The P2200 is remarkably silent as well due to QuietPower Technology it is outfitted with. Moreover, it rocks a Lo-Tone muffler that further reduces the noise it generates while making it more suitable for use with laptops and PCs.

Briggs & Stratton’s P2200 is equipped with a 1-gallon fuel tank, which is capable of providing approximately 6.5-hour continuous working time. Connectivity-wise, it features two 120V/20A ports, a single DC 12V/5A port, and a parallel-connector port that you can use to pair it up with another inverter generator that operates on the same level of voltage.

The only downside of P2200 is the fact that it (as well as all of its variations) is a tad more expensive in comparison to models with similar wattage. It is light and can fit in your car.

We believe, however, that its price tag is fair since it’s smaller, lighter, easier to handle, and substantially easier to store than most of its similarly-priced counterparts. In fact, based on plenty of consumer testing, it may very well be the top-level, No. 1 inverter generator on the current market, basically without a single drawback. Can be used at home, in cars – great features, and a great device!

As far as connectivity is of concern, WEN’s 56380i offers 2 120V slots, a single AC-120V TT-30R RV slot, a 12V DC slot, and one USB output. It is equipped with a variety of slots and receptacles, but it also offers a clear overview of them all via the digital onboard display. Even though its recharge plug feature leaves some room for improvement, it’s certainly one of the best inverter generator models out there. You can keep these generators at your home or garage, the devices remain stable; one of the best we saw on the market in recent years, top ratings.

Furthermore, it comes equipped with a set of rolling wheels that further boost its portability. We are looking at a 4,000-watt power capacity, making this fella one of the best inverter generators in terms of wattage

One of the best things about this inverter generator is its wireless control ability. The product’s package comes in features a small remote controller that you can use to access CPE 100573’s controls and settings while being up to eighty feet away.

It’s also decently quiet – approximately 64 decibels based on the official test – and packs 4 kilo-watts of strength; moreover, it’s also parallel ready, which means that you can couple it with additional inverters or hybrids via Para-Link ports. Speaking of connectivity, it sports a single 120 Volt AC RV port and two 120V AC 20A slots.

Best Inverter Generators Buying Guide – The Features, the fuel, the watts, the noise

There are only a couple of features you should look for in an inverter generator before buying one.

Top-level connectivity

Most people are easily distracted with wattage and portability, disregarding the amount and types of outlets that a generator has to offer. Consider your needs and pick accordingly – if you’re unsure, search for a model that offers at least three different connectivity ports, including a USB one. These features are just as important as the power in many cases.

Loudness when run

Inverters are meant to be quieter than regular fuel-powered generators. Even so, certain inverter generators are as loud as 70 decibels (or more). Regardless of what you intend to use your inverter for, make sure that it’s quieter than 60 decibels.

Intended energy use

Do you like to use your generator around the clock or only every once in a while? The batteries/motors of different generators are designed to fulfill different purposes and perform poorly when used in unsuitable settings.


Since everyone is limited by their budget, price is certainly a big factor to consider; however, it’s not the most definitive one. A general rule of thumb is that pricier models are a bit more reliable and versatile; wattage usually ramps up the price too.
