Top 3 biggest inverter generators reviews
We filtered through dozens of models available and found the following units more impressive than any other products.
Just so that you know, we were primarily interested in products whose wattage is high enough to keep most energy-hungry appliances running in an emergency situation.
Here are the three champions:
1. Honda Inverter Generator (Electronic Fuel Injection) Eu7000is- best 5000 watt inverter generator
With a 7000W peak wattage and 5500W continuous power, this is the champion of the champions and the go-to unit for those who own a bevy of equipment with an insatiable appetite for energy.
The sleek engineering of this tool makes it extremely popular and Honda deserves kudos for getting everything right with this powerful inverter generator.
Your neighbors will love the EU7000iS as its so quiet (52 – 58 dB) while you’ll be delighted with its terrific fuel efficiency (you get a staggering 18 hours out of the 5.1 gal tank).
And because of the electronic fuel injection feature, there’s little maintenance awaiting you with this.
We also think highly of the easy folding handles plus wheels (for transport and compact storage) as well as the life-saving electric start.
Also making this a star is the i-Monitor system (you stay updated of the hours of operation, RPM, wattage, and even diagnostics information) and the fact that it’s parallel ready (use the optional parallel kit).
In other words, you have the perfect unit for your back up power needs, RV, outdoor fun, and more in this.
- Ultra-quiet generator.
- Easy push button starting.
- Little maintenance.

2. Champion DH Series 6250-Watt Open Frame Inverter Generator with Quiet Technology
Gone are the days when Honda and other big names such as Yamaha used to be the options.
In fact, some of the best largest portable inverter generators come from some of the less known brands.
Champion is one such company and has the wonderful DH series open frame inverter generator (6250 starting watts and 5000 running watts rated) impressing.
This had everyone talking when it first debuted on the market and it remains an undisputed favorite among heavy-duty users thanks to its innovative construction.
Not only is this 50% quieter (69 dB) but it’s also 20% lighter too compared to similar 5000-watt generators.
And with the extended run time (12 1/2 hours on 25% load), a more fuel-efficient economy mode, and handy cold start technology (for quick starts in cold weather), you have unearthed for yourself a truly precious gem.
Also keep tabs on the current voltage, frequency, and even the operating hours easily via the Intelligauge.
Plus, the foldaway handle along with the never-flat tires makes storage and maneuvering a cinch.
- Bigger 4-gallon fuel tank.
- Nicely located touch controls.
- Excellent warranty terms.
- Cannot be paralleled.
3. Westinghouse open frame iGen4500DF Portable Inverter Generator
Arguably the best inverter generator for power tools, this relatively large inverter has a couple of nice features, the biggest one being that it accepts both gas and propane.
Talking about the specs, the 3500 running watts (and 4200 starting watts) are more than required by power tools.
Other essentials marking it out as job site ready is the tough steel fuel tank combined with the rugged steel frame.
Movement won’t bother you either as its 20-40 lbs. makes it lighter than most of the equally rated competition.
Like the rest, this OSHA compliant generator is ultra-quiet and fuel efficient (you get 22 hours runtime on the 2.6-gallon gas tank).
The efficiency mode further conserves power usage while the automatic low-oil shutdown and overload guard guarantee its safety.
All the important performance information is shown on the digital display in real-time thanks to the built-in data center.
Overall, we feel that this is potentially a godsend for DIYers or even shop owners.
- Easy to set up and use.
- Amazing display.
- Solidly constructed.
- No handles or wheels.

Best larger inverter generators buying guide
As hinted earlier, there are a few influential factors that can really affect your buying decision when it comes to the best large inverter generator.
Let’s quickly check out some of them so you can get a clear idea of which inverter model you should buy for devices that gobble up the most energy.
· What is the best wattage to select?
Of course, the biggest decision you have to make is select an appropriately-sized high wattage inverter generator and this comes down to these questions:
- How many appliances do you require to power?
- The maximum wattage (when you sum up the energy draw for all your appliances). As always with inverter generators, be sure to factor in both the surge and running watts.
- How long you typically want the generator to run when in use. As a general rule, longer runtime (on full tank) is more favored since you won’t be refueling it every few hours which can be quite inconveniencing.
· Size of the unit
Truth be told, these implements are generally huge compared to your typical inverter generator. But you don’t want it so big because how will you haul along to your tailgate party?
There are features that can further help with movement including wheels and folding handles and it’s a good idea to select a unit with such.
· Steer clear of too loud models
The decibels curve climbs with output because monstrous models generally need larger engines.
There are exceptions, however and manufacturers are getting ways of including noise canceling features in many of these generators.
You should narrow your search for the best large inverter generator down to brands with special noise deadening technology.
· More factors to keep in mind for you
There are several other extras, too like the type of outlets you feel will serve your needs best together with what you find down here:
1. What fuel source / type do you prefer?
A number of options are available, including propane and gasoline, and even hybrid generators (can use either gas or gasoline).
Each has advantages and disadvantages and you should pick what best fits your requirements.
For instance, propane generators are not as efficient as gas generators though propane burns cleaner than gasoline.
2. Unique additions
Most of the best 5000 watt inverter generator include bonuses that give more value.
A fuel gauge (to track fuel amount), an instant start system, overload warning lights, and maintenance reminders are just some of the things we have in mind here.
High power inverter generators will always come at a premium price because of the cleaner energy.
These best large inverter generators are even pricier, which means you’ll need a bigger budget.
But if you take a moment to think about what these power titans can do, you’ll realize that getting one could be a masterstroke for your mobile energy needs.
