This generator runs at 2,500 watts, but it can crank up to 3,300 starting watts to get bigger electric motors going without straining. While generators can be lifesavers in a storm, they often lose their reliability in hotter climates. This generator was designed with a top of the line liquid cooling system so that it stays cool even when the weather is unbearably hot. Not only does this system cool better, but it is also generally quieter than air-cooled models—this makes it a great choice for residential areas where you don't want to disturb your neighbors. Since it is a 22kW model, it can power most homes, but because of the wattage and cooling system, it is also expensive.
The best gas generators of 2024 for home, RVs, and emergencies

A no-frills dual-fuel generator that’s small enough to tuck away in the corner of a garage or in a truck bed, the Pulsar 2200-watt generator delivered an easy experience powering our test equipment. The 1.18-gallon generator can run for up to 8 hours on half load on a single tank of gas. When shopping for a generator, it’s easy to become overwhelmed by the available options on the market. While the following models vary in fuel type, electrical load, and intended use, each one earned a spot on this lineup by excelling in real-world tests. How long a generator can run depends on the load put on it, the size of the generator, and the size of the fuel tank.

The GP8000E uses a 420cc 4-stroke Generac OHV engine that features splash lubrication to keep the motor lubed at all times. This helps with start-up stress on the motor, helping it last longer and remain reliable. The motor also has a built-in COSense integrated carbon monoxide detection system that continuously monitors CO levels. The Generac has extended runtime thanks to the large-capacity steel fuel tank and built-in fuel gauge.
New Safety Technology for Portable Generators
The cooling system does make it a more complicated unit and it may require more maintenance than an air- cooled system. It can be a lifesaver in a summer power outage, so it may be worth it for you. This little guy only puts out 12,000 watts, so it may not be able to power an entire large house. But depending on the heating and cooling systems, it can supply power to most of a smaller one. This generator is a great option if you want a power backup for a few necessities. Sure, it’s still an investment, but it comes with a five-year warranty that covers parts, labor, and travel.
Once you’ve figured out your power needs, the next two major considerations are the physical footprint of the generator and the amount of noise it makes. Whether you have a small yard or many acres of land, you’ll likely need the generator near your home, so the size and sound matter. Unfortunately, with smaller size comes larger noise; the Briggs & Stratton 12kW generator is one of the loudest on our top five list. Additionally, neither Briggs & Stratton generator on our list comes with an Automatic Transfer Switch—those must be purchased separately. You can begin exploring the full selection of Generac home backup generators.
The listed performance numbers are a little better than those of the gas generators we tested, at 2,000 watts of continuous load and 3,000 watts of peak load. Those are the best-case-scenario numbers, and you should adjust them down if you’re using fewer or less-powerful batteries. The All Power 9000W gasoline/propane portable generator will run using either gasoline or propane with an electric or pull cord start. PerformanceTo test generators for performance, our expert engineers load up each model with a variety of essentials you might want to power during an outage, like a space heater, refrigerator, or window air conditioner. The best models take that in stride, while others bog down or even stall.
How do I correctly size a generator for my home?
Two 2,200-watt generators linked together, for example, behave like a single 4,400-watt generator. The ability to double up like this is a nice option to have, but it does bring the added responsibility of maintaining two engines instead of just one. The battery-powered Ego works indoors and eliminates a gas engine’s noise and hassles. It’s as strong as our gas-powered picks in power output, but it can’t match their run time, and its hours-long recharge times aren’t practical in a long-term outage.

If you’re not familiar with standby generators, here are some pointers on what to look out for when buying and operating. Generators generally are powered by one of three fuel sources—gasoline, natural gas, or propane. If you live in a hot weather climate, a liquid-cooled generator like the Generac Protector QS is a great option. It operates quietly and has a longer lifespan thanks to its closed coolant recovery system.
Furthermore, this Briggs & Stratton generator does not come with an Automatic Transfer Switch, which must be purchased separately. A smaller-output version of the previous generator, the Briggs & Stratton PowerProtect 10kW Standby Generator does exactly what the 12kW version does, just with less output and a more affordable price tag. The Briggs & Stratton 10kW generator is 50% smaller than competitors in the same class, meaning easier installation and the possibility of a more discrete placement around your home.
This Champion 7,500-watt dual-fuel generator delivers enough electricity to power up an off-grid jobsite or keep critical home circuits running through a utility outage. It includes numerous convenience features, like a push-button electric starter, covered outlets, and a fold-out transport handle. In our tests, the push-button starter worked perfectly, no matter the weather. Once installed, we tested the generator by shutting off the electricity at the meter, and it started automatically in about 15 seconds.
You’ll want to assess your power demands to choose the ideal transfer switch for your whole house generator. The size of your generator dictates the transfer switch capacity you’ll require. A transfer switch that aligns with your generator’s output ensures efficient power distribution across your household circuits. The KARNO generator is a fuel-agnostic solution that leverages a linear generator architecture to produce electricity economically and efficiently. Under the terms of the LOI, H2EG is slated to receive their first five KARNO generators in the second half of 2025, each capable of producing an estimated power output of 200 kW, with a total capacity of 1MW. H2EG also plans to leverage the KARNO generators combined heat and power capabilities and utilize the excess heat to improve efficiencies in their manufacturing process.
We also charged it with solar panels, but the day was slightly overcast, which kept it from charging quickly—it took about 5 hours to charge from 28 to 100 percent. A sunnier day or stronger solar panels would likely have charged it more quickly. When fully charged, we used it to run our fridge, a miter saw, lamps, a laptop, and cell phone—not all simultaneously. We made about 20 cuts with the miter saw and noticed no lag in the saw’s power.
Portable generators are best suited for temporarily powering an appliance or two and smaller tools, or electric-powered items, like fans or lights. For limited power needs, use a portable generator like the WEN DF475T Portable Generator with 4,750 running watts. Portable generators typically operate using gasoline as their fuel source. (See "Fuel Source," above.) For this reason, it’s crucial that you never operate a portable generator inside an enclosed space—including your house, garage, or shed. In general, portable generators make life more bearable during short power outages but don’t support all the creature comforts such as a central air conditioning system, water heater, and other large appliances. Inverters are a type of portable gasoline-powered generator that use less fuel and offers quieter operation by constantly adjusting engine speed to power only what's using the energy load.
