Best Inverter Generator for Jobsites

Champion’s 4250W open-frame inverter generator series includes four models, and any one of them is a fine choice for jobsite use. The 201185 is the most full-featured of the group and includes carbon monoxide detection, remote electric start, parallel capability, and a generous fuel tank that offers outstanding runtime. It’s a fantastic all-around option that can be just as happy on your RV or tailgating as it is on the jobsite.

Also Consider

• Westinghouse 4500W iGen4500DFc (Jobsite Rating: 8.5) – $1199

Best Inverter Generator for Emergency Power

Westinghouse’s ecoGen10000 is near the top of the range we recommend for portable emergency power needs. At the same time, it’s not nearly as heavy as competing models in the same power class, so it’s easier to move than you might think. The biggest downside is that it’s noticeably louder that the other models we considered.

Also Consider

• Champion 8500W 201175 (Emergency Power Rating: 8.6) – $2199
• Honda 7000W EU7000iS (Emergency Power Rating: 8.6) – $4499
• Duromax 7000W XP7000iH (Emergency Power Rating: 8.5) – $1799

Best Inverter Generator for 30-Amp RVs

This race came down to Westinghouse and Champion, and either one will be an excellent choice for your 30A RV needs. What pushed Westinghouse into the win column was its incredibly low operating noise level—just 52 decibels. Even among quiet generators, that’s really quiet. Runtime and efficiency also rate very high, and the iGen4500DFc has a luxurious feature set.

Also Consider:

• Champion 4500W 201184 (30A RV Rating: 9.1) – $1099
• Duromax 4500W XP4500iH (30A RV Rating: 8.5) – $1499

Best Inverter Generator for 50-Amp RVs

Not many brands make inverter generators that are a good fit for 50A RVs. In the final tally, the three that made our cut were separated by only 0.2 points. Edging out Champion and Westinghouse, DuroMax’s XP11000iH offers lower noise and an impressive runtime, but even in those categories, it was a close call.

Also Consider:

• Champion 11000W 201407 (50A RV Rating: 9.2) – $2499
• Westinghouse 11000W iGen11000DFc (50A RV Rating: 9.0) – $2299

Best Inverter Generator for Camping and Tailgating

When it comes to camping and tailgating, Honda’s EU2200i nails it with a lightweight and ultra-quiet design. It doesn’t have the best runtime or fuel efficiency, though. What it does have is the best small engine you could hope for and quality that exceeds what anyone else has to offer in a compact generator.

Also Consider:

• Westinghouse 2800W iGen2800c (Camping/Tailgating Rating: 9.2) – $679
• Champion 2500W 201323 (Camping/Tailgating Rating: 9.1) – $629

A Few Other Inverter Generators to Consider

What You Should Know About Inverter Generators

What is a Generator?

A generator is a machine that uses an engine to produce alternating current (AC) electricity so you can plug devices into it for power.

What is an Inverter Generator?

An inverter generator is a type of generator with additional electronics that produces alternating current (AC) and then “cleans” it by converting it into direct current (DC) and then back to AC. The result is pure sine wave energy or modified sine wave energy.

What are Watts?

Watts are a measure of power calculated by the equation: volts x amps = watts

What are Continuous Watts?

Continuous watts are a rating of the maximum watts an inverter generator produces at a steady state, also known as 100% load.

What are Surge/Startup Watts?

Surge, or startup, watts are a rating of the maximum watts an inverter generator can produce momentarily to handle the higher initial surge of a device starting up.

What is Pure Sine Wave Energy?

Pure sine wave energy is electricity with a smooth waveform like what comes from the energy grid. It is more stable than modified (square) sine waves and the most suitable for electronic devices.

What is Modified (Square) Sine Wave Energy?

Modified, or square, sine wave is electricity that has a stepped, or square, waveform with higher voltage instability (but not as high as the “dirty” energy that comes from a standard generator) and isn’t as stable as pure sine wave energy.

What is Total Harmonic Distortion (THD)?

Total harmonic distortion (THD) is a measure of how stable electricity is. Pure sine wave energy is understood to be less than 6% and many inverter generators are capable of producing energy at a THD under 3%.

How is Noise Measured?

Generators’ noise ratings are measured in decibels from 7 meters away (about 23 feet). With each rating, you should also see what wattage load it was tested at (25%, 50%, etc). Because inverters adjust engine speed with the load, you can see significantly lower noise levels if it’s measured at a lower load level.

What is Runtime?

Runtime measures how long the unit will run at a given load, starting with a full fuel tank. Pay attention to the details—some brands rate runtime at 25% while others use 50% loads, and some tell you what to expect at 100% load. Every model runs longer at lower loads.

What Size Generator is Best?

There are some specific recommendations in the How to Choose the Right Model section below. Those are good guidelines to help you get started, but you may want to see our guide on How to Choose the Right Size Generator to help you assess your specific needs.

Inverter Generator vs Standard Generator

Inverter generators are nice, but not everyone needs one. Here’s a case for each type to help you decide which one is right for you:

Reasons to Buy a Standard Generator

• Less expensive
• Higher power levels available
• Easier to service
• Dual and tri-fuel models available

Reasons to Buy an Inverter Generator

• “Clean” pure sine wave energy that’s friendly to electronics
• Quieter
• More fuel efficient
• Lighter
• More compact
• Many models are parallel capable
• Dual and tri-fuel models available

If you have room in your budget for an inverter generator, it’s the way to go in most cases.

On the other hand, a standard generator makes more sense if you want more than 10,000 watts of power, have a lower budget, expect it to work on tough jobsites, or want a simpler unit.

Inverter Generator Features to Consider

Once you figure out the performance and basic design of the generator you want, there are additional features that can make your experience more convenient. Here are the most impactful ones we look for:

Carbon Monoxide (CO) Detection

Carbon monoxide detection is all but standard on new generators today. A sensor measures the amount of CO in the air and shuts the generator down if the level gets too high. Often, there’s also an audio alarm to alert anyone close by.

Parallel Capability

Parallel capable units can be connected with a cable to combine their output to produce more power. It’s helpful if you don’t want a single larger unit due to space or weight considerations.

RV-Ready

If your primary goal is to have power for your RV, choosing a model that has an RV-ready plug can keep you from having to buy (and keep track of) an adapter. Just plug your RV into the generator the same way you would to a standard RV power supply. For 30A RVs, you’re looking for a TT-40R connection. For 50A models, it’s a 14-50R outlet.

Dual-Fuel Capability

The ability of a generator to use two fuel sources, usually gasoline or propane. Keep in mind that fuel sources other than gas typically reduce the power output.

Tri-Fuel Capability

The ability of a generator to use three fuel sources—gasoline, propane, or natural gas. As with the dual fuel option, propane and natural gas typically have lower power output levels than gasoline.

Electric Start

Some models use a small battery to power a push-button ignition. It’s far more convenient than having to pull a cord to get your generator started.

Remote Start

An upgrade to an electric start is a remote start. Using either a remote control or a Bluetooth-based app, you can start or shut down your generator.

Bluetooth Connection

Some inverter generators offer a Bluetooth connection to the unit. Some may have remote starting capability, but almost all give you a fuel status, current load, and other helpful information.

GFCI Outlets

Ground Fault Circuit Interrupter (GFCI) outlets are an extra level of safety that helps prevent shock or electrocution, especially when water is likely to be nearby. That’s why you often find GFCI outlets in your kitchen and bathroom.

How to Choose the Right Model and How We Make Our Choices

Best Inverter Generator For Jobsites

For a typical jobsite, I prefer a generator with continuous power in the 3400W – 4000W range. This gives you roughly 30A worth of 120V power to handle a large tool, such as a table saw, miter saw, or circular saw, plus wiggle room for battery charging.

While there are jobsites and crews that require more power, this typical size in this power class is easy to manage and it’s possible for one person to lift it in and out of a truck bed.

High runtime and fuel efficiency are bonuses that can reduce how much spare fuel you have to carry and how often you need to refill. Most generators in this class should give you at least enough runtime to make it to lunch and then again to the end of the day with a refill in between.

The noise level isn’t as critical on jobsites as it is for other applications. While reducing the overall noise on site is nice, it’s a low priority compared to the other characteristics we consider.

Of the main applications you might want an inverter generator for, jobsites are the easiest to go with a standard generator instead.

Must-Have Features

• Wheel kit (unless you’re mounting it to the truck)
• Folding handle

Nice-to-Have Features

• GFCI outlets (required by OSHA for models over 5000W)
• 240V capability
• USB ports
• Carbon monoxide detection
• Electric start
• Remote start
• App-based fuel monitoring
• Dual-fuel capability

Best Inverter Generator For Emergency Power

I know there are people who will disagree with me on this (my boss is one of them), but I like a generator with continuous watts in the 5000W – 8000W range for emergency power. No, that’s not enough to power most entire houses, but it is enough to run the most important appliances plus lights, fans, TVs, modems, and routers. You can also pick your battles during extended outages to run the water heater, washer/dryer, and other items that aren’t as critical in the short term.

Since you have to store these models and roll them out, I’d rather manage the power I have than try to lug out a monstrous 12,000W unit. Think about how much of a pain it would be to wheel your super-heavy inverter across saturated soil following a hurricane or in the snow during a blizzard.

As these are large inverter generators, they consume more fuel. Fuel efficiency is a high priority since you often need them during times when access to fuel is uncertain. Runtime is helpful, but fuel efficiency rates higher in my book.

If you really need 12,000+ watts, I highly recommend you look into a whole-house generator. Their convenience, automatic maintenance, automatic starting/switchover, and peace of mind are worth the extra cost if you can swing it in your budget.

Must-Have Features

• Carbon monoxide detection
• Wheel kit
• Folding handle
• 240V capability

Nice-to-Have Features

• GFCI outlets
• Electric start
• Remote or app-based starting and shutdown
• Bluetooth fuel monitoring
• Dual or tri-fuel capability

Best Inverter Generator For RVs

The power level I recommend for RVs depends on which type you have. If yours has a 30-amp electrical system, go with 3400 – 4000 continuous watts. This ensures you can use the maximum capabilities of your RV. However, there’s no benefit in going with a generator that has more power than the RV can use.

Similar to the jobsite recommendation, this power class’ size and weight are relatively easy to manage.

For 50-amp RVs, you’re looking at split-phase electrical systems that can handle 50A on each phase. I’d go with 6000 continuous watts at a bare minimum and as high as 12,000 continuous watts to max out your potential.

Keep in mind that generators in this power class are significantly heavier, so consider where you’re going to store it and how you’re going to move it if necessary. It’s worth doing a power needs assessment to see how much power you actually need for your setup so you don’t overbuy.

Regardless of the type of RV you have, a low-noise model is a must. You’ll sleep better, and your neighbors will be much more friendly toward you.

High runtime can be a big deal. With your overnight power load, you want to make sure you can run 8 – 10 hours so you’re not getting up at night to refuel. High fuel efficiency is also helpful to reduce the amount of spare fuel you need to carry and cut down on your expenses.

Must-Have Features

• Carbon monoxide detection
• Parallel capability if you want to combine two smaller generators instead of using one larger one
• 30-amp or 50-amp outlet (depending on your RV)
• Wheel kit (unless you have a stationary spot on your RV for the generator)

Nice-to-Have Features

• GFCI outlets
• USB ports
• RV-ready outlet (TT-30R for 30A, 14-50R for 50A)
• Electric start
• Remote starting
• Bluetooth capability for fuel monitoring
• Dual or tri-fuel capability

Best Inverter Generator For Camping and Tailgating

Tailgating and camping don’t require nearly as much power as other applications, while size and weight become much higher considerations. I like a suitcase-style model that has 1800 – 2200 continuous watts. This gives you 15 – 20 amps to work with, powering any 120V appliances or devices you want to run, including microwaves, air fryers, and coffeemakers. Just be aware that you might not be able to run multiple appliances at one time.

The weight of these units can be under 50 pounds, making them easy to carry. Plus, they’re compact, taking up much less space in the back of your truck.

While the fuel capacity of these models can be under a gallon, their small engines (usually around 80cc) are incredibly fuel efficient. For tailgaiting, it’s possible to head out with a full tank of gas and not need any spare fuel. For camping, it just depends on how long you’re going to be out. Either way, the cost of fuel isn’t as high of a consideration, but the runtime can make a difference in which one you choose.

Must-Have Features

• Carbon monoxide detection
• Comfortable carry handle and manageable weight

Nice-to-Have Features

• USB ports
• Electric start
• Remote start
• Bluetooth fuel monitoring
• Dual-fuel capability
• Parallel capability if you want to have the option for higher power for other applications
• Wheels and a telescoping handle
