For this guide, I took a look at some of the best brands out there and compared power output, the number and type of outlets, the type of fuel required, consumer feedback, and — as always — price.
Everyone’s needs are different, so I tracked down great inverter generators ranging from portable options for your campsite or power tools to permanent power stations that can take your entire home off-grid if the need arises. My research took me to manufacturer manuals, forums, online reviews, and my own hands-on experience. The best inverter generators that are good enough to make this list are worthwhile investments that will have your back when you need them most.
Best Inverter Generators: Reviews & Recommendations
Best for RV Camping: Generac GP3000i
Key Features
- 2,300 running watts (3,000 surge watts)
- 60 pounds
Pros
- Quiet operation
- Can run in parallel with another GP3000i for double the power
- Safe to use with sensitive electronics
- Best for powering select appliances or a campsite
Cons
- Can be cumbersome to carry, especially with a full tank
- Underpowered for home backup
The Generac GP 3000i is a versatile inverter generator that’s perfect for powering a few electronics while you’re RV camping. It’s light enough for one person to carry, but still powerful enough to handle certain appliances in addition to your personal electronics. When my neighborhood lost electricity for a few days one summer, I used a GP3000i to run my chest freezer long enough to save about a hundred pounds of meat from spoiling.
The heart of this inverter generator is a 149cc engine that generates 2,300 running watts and 3,000 surge watts. Its 1.06-gallon tank will run the engine at 50 percent capacity for 4.5 hours. One person can move this 60-pound generator by its carrying handle, but it can be a little cumbersome. Plan on storing it someplace where you don’t have to carry it very far to use it. The system is simple and reliable, but Generac includes a three-year residential use warranty, just in case.
Using the Generac GP3000i is simple and straightforward. Start-up and shut-down graphic instructions are clearly printed on the top of the housing. The pull starter is more labor-intensive than electric ignition, but it’s incredibly reliable and doesn’t require much effort. Even after sitting idle for months at a time, my GP 3000i starts within three or four pulls. A clearly marked dial switches between choke (for cold starts), run, and off. You can let the engine idle at a constant speed or switch on the economy mode to let it raise or lower engine speed to match the power demand from the outlets.
The GP 3000i is a little bit underpowered for home backup, but my experience proves that it can power select appliances in an emergency. Around the campsite, it’s just right. Having multiple outlet types—including two USB ports—makes it great for charging everything from a pellet smoker to your phone at the same time.
Best Compact: Honda EU2200i
Key Features
- 1,800 running watts (2,200 surge watts)
- 47 pounds
Pros
- Excellent build quality and quiet operation
- Can run in parallel with another EU2200i for double the power
- Small enough to bring with you on the go
- Best for powering the essentials
Cons
- Limited power output
- Expensive
If you just need to power a few small electronics, you can get by with a small inverter generator like the Honda EU2200i. This compact inverter generator is perfect for charging things like your phone, handheld radios, or power tools. It’s the right size for car camping or keeping on hand for short power outages.
The EU2200i uses a 121cc engine that’s good for 1,800 running watts and 2,200 surge watts. That’s adequate for all your small devices or something as large as a space heater. The tank holds just shy of a gallon of gas, but that should last between three and eight hours, depending on how much power you use. Honda generators are known for being extremely reliable and quiet, so this one should give you many years of use. At 47 pounds, it’s also one of the more portable options out there.
Honda designed this generator’s GXR120 engine with an automatic mechanical decompressor to make pull-starting it as easy as possible. Instructions are printed on the housing, and controls are color-coded. Even the oil filler tube is thoughtfully designed to minimize spills and make ownership painless.
There are less expensive generators of this size (or larger), but you have to keep an eye out for cost-cutting measures. Honda equipped the EU2200i with safety and convenience features that some manufacturers reserve for larger generators. This one automatically shuts off if carbon monoxide levels become unsafe or if the oil level drops too low. It’s also compatible with Honda’s My Generator app, which lets you monitor the EU2200i’s performance and power it down remotely.
Best Budget: Predator 57063
Key Features
- 1,100 running watts (1,400 surge watts)
- 33 pounds
Pros
- Light enough to carry with one hand
- Clean electric signal is safe for sensitive electronics
- Built-in protection against carbon monoxide, overload, and oil starvation
- Best for powering the essentials
Cons
- Limited power output
- Only holds 0.65 gallons of gasoline
Getting quality gear for a low price can be challenging; it’s often hard to tell what’s inexpensive and what’s just plain cheap. The predator 57063 is nothing fancy, but it’s earned a loyal following in consumer inverter generator reviews by offering a lot of bang for the buck.
You’ll only get 1,100 running watts and 1,400 surge watts out of this inverter generator’s little 54cc engine, but the tradeoff is an empty weight of just 33 pounds — the lightest of any generator on this list by a significant margin. That kind of power won’t keep many appliances operational, but it’s adequate for essentials like your phone, rechargeable flashlights, and GPS devices. Another upside is efficiency; the tiny engine sips gas so slowly that the 0.65-gallon tank can last up to seven hours at 25 percent load.
Predator keeps the price low with a manual choke and a pull starter. It still comes with a carbon monoxide safety shutoff and indicator lights for low oil, overload, and output. Sound levels are higher than some larger generators at an estimated 60 decibels, so you might have to be mindful of when and where you use it if you want to be a good neighbor at home or a busy campground.
Are there better generators out there? Absolutely — but not at this price. Anytime you can spend less than $500 on one of the best inverter generators with a manufacturer warranty, you’re getting a good deal. As long as the limited power capacity and a little extra noise don’t bother you, there’s no need to spend more.

How to Choose the Best Inverter Generator
Power capacity
The first step in choosing an inverter generator is figuring out how much power you need. Look for labels on the appliances and devices you want to use, and add up the power ratings to get an idea of how much electricity you’ll likely consume per hour.
Portability
Inverter generators that are capable of powering your home will be far too big and heavy to take on the road. If you want to bring your inverter generator camping to power an RV or a few small devices, there’s no need to take on extra weight and expense.
Fuel
Not all inverter generators require the same fuel. The best inverter generators for you might burn gas, propane, diesel, or natural gas. Some generators can burn more than one type of fuel.
Manufacturer support
Inverter generators are typically very reliable, but they’re still machines that will require maintenance eventually. If you ever need more than routine generator maintenance that you can do at home, being able to call a trained technician or order OEM parts can save you from having to replace the whole thing.
Solar vs. Fuel Generators
Solar generators are one of the latest innovations and offer some appealing benefits over their fuel counterparts. The solar panel charges a portable power station, which is what you’ll use to power appliances, power tools, or charge your phone. These portable power stations vary in size and power output, so it’s important to match the power station to what you plan to power with it. The negatives of solar generators is that unless your power station is fully charged, you have to wait sometimes an entire day for the sun to power it up. That’s not ideal during a storm.
Fuel generators on the other hand can be used no matter the sun exposure, providing you have fuel. Of course, their downside is that they are loud and produce carbon monoxide—you can’t use them indoors.
If you’re looking for a portable and quiet way to power small appliances, a solar generator is ideal. If you need a lot of reliable power you still can’t beat a fuel generator.
FAQs
If it seems like power outages have become more of a problem in recent years, you’re right. Severe weather events are causing an increasing number of households to go without electricity, and the problem isn’t just affecting northern states with traditionally harsh winters.
In 2021, more than 4.5 million Texans lost power due to a winter storm. Thanks to strains on its electric grid, California commonly runs low on power even when the state isn’t dealing with a winter storm, wildfire, or flooding. It’s important to have a backup power source for emergencies.
Conventional generators run at a constant speed and produce the steady power output. The electrical current can vary, though, which isn’t good for some sensitive electronics. Old-school generators will still get the job done in most cases, but they may not be the best generator for you.
Inverter generators automatically adjust engine speed depending on demand to get the most out of each gallon of fuel. They also deliver a cleaner electrical current than conventional generators by generating it in AC, converting it to DC, and finally converting it back to AC to create a cleaner and more consistent current. If you have the option to choose between a generator and an inverter generator, the inverter generator will be quieter, more efficient, and more modern.
To determine which size of generator you should buy, start by identifying the devices and appliances you want your inverter generator to power. Check the label near the power cord to see how many peak watts each uses. Add those up to get the total number of watts you need and look for a generator with the same rating or greater.
Keep in mind that some appliances have one rating for general operation and another during startup; this is called surge power. For example, a refrigerator may require several times its normal operating power when you first turn it on.
It’s better to have too much power than not enough, but don’t get carried away. Generators create electricity but they can’t store it. If you don’t use or have a power station to store excess power, you’re just burning gas (and money) while getting nothing in return.
Solar generators can be a fantastic alternative to fuel-burning generators if you live someplace with lots of intense sunlight. They produce no fumes or sound, making them great for use indoors or at quiet campsites.
Solar panels struggle in cloudy climates, where you’re likely to draw more electricity per day than the panels can replace. They’re also very expensive compared to generators that use internal combustion. So which is best? That’s for you to decide.
Final Thoughts on the Best Inverter Generators
Power outages can impact you regardless of where you live. Besides being a cheap form of insurance, an inverter generator can also keep you powered up when you go RV camping or need to work in a remote location. The Honda EU7000is is the best inverter generator. If you’re on a budget or need to be more mobile, the Generac GP 3000i is a solid choice.
No matter which inverter generator you pick, make sure to stay on top of the maintenance schedule, exercise it by letting it run for a few minutes from time to time, and be aware of how much load you can place on it.
