How we chose the best portable generators

I am what is commonly referred to as a “gear junkie” in that I am borderline obsessive about testing a wide range of tech tools, particularly those relevant to the outdoors and varying home DIY projects. Portable power generators not only rank among those tech tools in and of themselves but have also been essential to charging all the other electricity-hungry items like phones, laptops, drones, power tools, ebikes, and my trusty van conversion, not to mention an RV or home when the lights go out. I’ve also written guides about the best solar generators and inverter generators for PopSci.

That being the case, I’ve had the opportunity to test out generators of every variety, and I’ve combined that experience with insight from other PopSci writers who have tried everything from small, straightforward power stations the size of a shoebox to big, feature-rich behemoths designed to power a small army. Accordingly, I know which generators provide plenty of juice and which fizzle out under a full power load. Armed with this knowledge, I have spent over a decade reviewing generators and other equipment for outlets like Popular Science, Popular Mechanics, the Daily Beast, Thrillist, and more. Occasionally, I’ve arrived at split decisions for certain categories, so to break the tie, I’ve looked to input from my fellow experts as well as reviews from real-world buyers.

The Champion 200988 hits the sweet spot for RV generators by pretty much every metric. It runs on both gas and propane, making it easy to find fuel when out in the wild. Its 4,500W output is more than enough to power almost any RV—even with the air conditioner turned on. It’s relatively quiet, so it won’t ruin the outdoorsy mood. And it offers straightforward, intuitive operation. 

What’s more, it’s exceedingly rare to find a generator that delivers so much wattage in such a portable package. Compact, squared off for easy packing, and equipped with sturdy handles and wheels, it’s easy to bring along in the RV. While its weight is just under 100 pounds, not exactly featherlight, it’s also not unmanageably heavy. And while I prefer the dual-fuel version, there are also single-fuel gas and propane options that feature a remote start, allowing you to switch it on or off without leaving the comfort of your camper.  

Best for home backup: Westinghouse 9500 Portable Generator

Pros

• High wattage
• Remote starting
• Long lifespan

Cons

• Pretty heavy

When the lights go out at home, the Westinghouse 9500 is a solid backup in every way you could want it to be. It’s certainly not light, but its handles and wheels make it easy to maneuver into place—my 70-year-old mother carts hers around with no problems. Its above-average wattage is plenty strong for most household demands, and its 6.6-gallon tank allows for an admirable 11-hour runtime. A remote starter allows you to switch it on without braving the storm. And Westinghouse generators are built solid, typically lasting through many years of use without issue.

It’s also equipped with plenty of smart safety features. Circuit breakers, low-oil auto shutdown, and rubber covers over the plugs reduce the potential for various risks. A (sold separately) smart switch allows it to switch on automatically when utility power goes out. And it’s relatively quiet, producing roughly the same decibels as a vacuum cleaner. For all practical purposes, it’s exactly what you want from a home backup generator.

• Wattage: 2,200 peak/1,700 running
• Power source: Gas 
• Weight: 46.3 pounds

Pros

• Very portable
• Parallel capable
• Quiet operation

Cons

• Not for high-power use

The great thing about the Craftsman C0010020 is that it does a little bit of everything right, and it does it without breaking the bank. While its modest wattage probably isn’t going to keep an entire house or RV going, it’s plenty to keep a few essentials like the fridge, lights, and key devices powered—or even a lower-draw air conditioner. It’s parallel capable, meaning you can chain it to a second generator to double the output when you need more juice. It’s also lightweight, quiet, and dependably built. 

There are other generators out there in the $500 neighborhood, but if they deliver on all the promises above, I haven’t seen them.

• Power source: Gas and propane
• Weight: 240 pounds

Pros

• Dual fuel versatility
• Very high power output
• Helpful data display

Cons

• Very heavy

The main benefit of a dual-fuel generator is in the name: the availability of two fuel options, which can be essential in an emergency situation. The DuroMax XP 13000HX delivers that versatility along with outstanding power output, intuitive operation, and reliable, long-lasting durability. I’m also a big fan of the data display, which provides useful information like voltage, hours of operation, and even a countdown to the recommended maintenance. A CO2 safety switch also detects carbon monoxide and then shuts the generator down if the levels become dangerous. 

This is definitely one of the heavier generators on the list, but it’s equipped with strong handles and smooth-rolling wheels that make it easy to move around. It also boasts a super-heavy duty 50 amp outlet, so in other words, this thing is a true beast. 

Most portable: Bluetti AC180 Portable Power Station

SEE IT

Why it made the cut: As portable as they come with great stats all around, this is the definition of go-anywhere power. 

Specs

• Wattage: 2,700 peak/1,800 running
• Power source: Solar or wall plug
• Weight: 37.4 pounds

Pros

• Extremely portable
• Solid power stats
• Plenty of outlets

Cons

• Dual solar inputs would be nice

If you’re looking for an ultra-portable box of on-the-go power, the Bluetti AC180 is it. The lightest and most compact on our list, it still has solid power chops thanks to its 1,152Wh capacity and ability to temporarily crank up its power output as high as 2,700W via the brand’s app. That capacity can be expanded via Bluetti’s new add-on batteries, and it can be fully charged within an hour. 

While adding a second solar input wouldn’t hurt, if you’re looking for a reliable box of power that you can bring along pretty much anywhere with ease, you’ve found it.

What to consider when shopping for the best portable generators

A portable generator tends to be a pretty big investment not only financially but in that it’s a piece of equipment that you plan to rely on—potentially in emergency situations—for many years to come. This being the case, there are several key considerations to remember when choosing the right one for your needs: 

Power output

First and foremost, you need a generator that will meet your electricity needs. When shopping for generators, you’ll typically see output expressed via two numbers, both of which are measured in watts (W). “Running” or “rated” output is the typical amount of watts produced at any given time, while “Peak” output is the amount it can produce in momentary surges, while switching on a power tool or air conditioner, for example. Read the wattage requirements for the various things you expect to power, total them up, and then look for a generator that delivers the appropriate output. Generally speaking, if you’re just looking to keep a few devices charged, 2,000W is the most you’ll need. For power tools, RVs, or a refrigerator, you should aim toward 4,000W. If you expect to be powering a full home, however, you will want at least 7,500W.

Fuel type and capacity

Generators almost always run on either gas, solar power, or, in the case of dual-fuel models, a combination of gas and propane. Which is right for you depends on considerations like access and the environment. Gas is typically the most convenient option as it can be acquired pretty much anywhere, though it pollutes more and tends to deliver louder operation. Adding the propane option provides greater versatility, which can be helpful if you’re out in the wild or in the event of an emergency, and it also produces less harmful emissions. (We love it in our grills, so why not our generators?) Solar is an environmentally friendly, nearly silent fuel, but it relies on the availability of sunshine and can’t deliver the same level of wattage as fossil fuels.

Next you need to consider capacity. The larger the fuel tank or battery capacity, the longer a generator will provide power, but it also increases the weight. If you plan on using your generator at home, a larger model that can be wheeled around is a fine choice. If you’ll be packing your generator along on camping trips, however, you’ll probably need to compromise some capacity in favor of lighter portability. 

Starting type

With gas or propane-fueled generators, you’ll almost always have the option to use a recoil cord and an electric starter, as it’s fairly standard for generators to come with both these days. The cord requires a lot of physical effort but will allow you to start the generator under any condition, while the electric start fires things up at the push of a button, though it won’t work if the internal battery is drained. Some models offer remote starters that you can fire up from the comfort of your home or RV. This isn’t really a consideration with solar generators as they tend to be plug-and-play.

Operating noise

Generators can be extremely loud, so volume should be a consideration if you don’t want to bother the neighbors at home or disrupt the peace and quiet while camping. While there are exceptions, typically speaking, the larger and more powerful a generator is, the louder it gets. The best portable generators tend to boast heavy shielding to reduce noise, though this only helps up to a point. 

If noise isn’t much of a concern, then go big and go loud. But if you want to minimize the racket, choose a smaller model, a dual-fuel that uses propane (which is somewhat quieter than gas), or the near-silence of solar.

Plugs

If a particular model doesn’t have the plugs you need, then it’s not much use to you. Most mid-large-sized generators come with AC outlets of 20-amp and 30-amp ratings, which will allow you to plug in most devices and RVs. Smaller units, especially solar, frequently don’t include a 30 amp port, so they might not work for your RV needs. If you’re looking for true max power output, you’ll need one of the few and far between generators with a 50-amp plug.

A good portable generator can not only be useful when camping or off-grid, but it can be vital and even life-saving in an emergency. While theoretically, you want as big a generator as possible, you also want one that’s actually portable, so get a model suited to your needs rather than the largest you can find. Bigger isn’t always better, especially when it comes to mobility. Try to strike the balance between the two appropriate to your circumstances.
