Six picks across every price tier, with honest pros and cons. Know your wattage needs first — use our free calculator — then find the right generator below.
Choosing a home backup generator comes down to three things: how much power you need, how you'll use it, and your budget. The "best" generator for a storm-prone rural home with a well pump is completely different from the best one for a suburban apartment dweller who just wants to keep the fridge and phone charged during the next outage.

Champion is the go-to brand for value-oriented buyers, and their 3,500W unit earns its reputation. It handles a refrigerator, sump pump (1/3 HP), several lights, and a window AC (5,000 BTU) without complaint. The 212cc OHV engine starts reliably and Champion's 3-year limited warranty is one of the best in the budget category.
It won't run a well pump or a large window AC, and it's louder than inverter generators (around 68 dB at 23 feet), but for the price it's hard to beat. Ideal for homeowners who want solid storm backup without spending over $600.
Best for: Renters, suburban homeowners, basic storm backup
The WEN 56200i is the best-value inverter generator on the market, full stop. It produces clean, stable power (THD <1.2%) that's safe for laptops, phones, CPAP machines, and smart TVs. At 51 dB, it's barely louder than a normal conversation — perfect for campgrounds and quiet neighborhoods.
The trade-off is capacity. At 1,600W running, it won't run a window AC or sump pump. It's a lights, phone chargers, fridge, and TV machine — not an HVAC machine. Think of it as the right tool for minimal, electronics-friendly backup.
Best for: Camping, RV, electronics-only backup, CPAP users
The DuroMax XP4850EH shines precisely when gasoline is hard to find after a major storm. Dual-fuel capability means you can run it on propane from your existing grill tank when gas stations have hour-long lines. Electric start is standard, and DuroMax's build quality is a step above most value-brand generators.
With 4,850 running watts on gas, it comfortably handles a refrigerator, sump pump (1/2 HP), furnace fan, lights, and small window AC simultaneously. The 3,850W surge capacity handles the largest single motor. Outstanding value at this price tier.
Best for: Storm preparedness, rural homes, dual-fuel flexibility
The Westinghouse WGen7500 is the most popular full-home backup generator for good reason: 7,500 running watts covers almost every combination of essential appliances, remote start (key fob included) makes it easy to restart from inside during bad weather, and Westinghouse's reputation for reliability and warranty support is excellent.
At 9,500 starting watts, it handles a 2-ton central AC system with room to spare. A transfer switch-connected WGen7500 is the setup we'd recommend for most American homes seeking real storm protection. The 6.6-gallon tank provides up to 16 hours of runtime at 25% load — enough for two nights without refueling.
Best for: Most homeowners, central AC, transfer switch setups
The Honda EU7000is is the gold standard of portable inverter generators. Electronic fuel injection (rare in generators) makes it easier to start in cold weather, more fuel-efficient, and requires less maintenance. The inverter technology produces exceptionally clean power — safe for any electronic device. At 52 dB it's remarkably quiet for its output class.
The 5,500W continuous rating with 7,000W surge handles a well pump, window AC, refrigerator, and electronics simultaneously with clean power. It's overkill for most use cases, but for those who demand the best — remote property owners, medical equipment users, work-from-home professionals — nothing portable beats it.
Best for: Serious home backup, medical equipment, those who buy once and buy right
When the WGen7500 isn't quite enough — large homes, 3-ton central AC, multiple heavy loads — the WGen12000 steps up. 12,000 running watts and 15,000 starting watts is serious power in a portable form factor. It handles a 3-ton central AC, refrigerator, well pump, lights, and electronics simultaneously without breaking a sweat.
Remote start key fob is standard. The twin-tank design holds 6.6 gallons for reasonable runtime. At this output level, you're one step below a standby generator in capacity and a major step below in price. For large homeowners who face regular outages and want portable flexibility, the WGen12000 is the pick.
Best for: Large homes, 3-ton AC systems, whole-home minus heavy 240V loads
Before you read another review, use our free generator size calculator. Select every appliance you need to power simultaneously, and the calculator will give you the total running watts, peak starting watts, and a specific generator size recommendation. This single number narrows your options from dozens to two or three candidates.
If you're running laptops, TVs, CPAP machines, or other sensitive electronics, choose an inverter generator. The cleaner power waveform prevents damage to microprocessors and power supplies. If your loads are primarily motors and resistive heaters, a conventional open-frame generator gives you more watts per dollar. The WEN 56200i and Honda EU7000is represent inverter; the Champion 3500W and Westinghouse WGen7500 are conventional.
Gasoline is the most common fuel type and available everywhere normally — but after a major storm, gas stations run out or lose power. Dual-fuel generators (like the DuroMax XP4850EH) solve this by also accepting propane from a standard grill tank. If you have natural gas or propane service, a standby generator connects directly to your supply line and never needs manual refueling.
A portable generator connected via extension cords works, but a transfer switch is worth the investment. A manual transfer switch (installed by an electrician for $300–$800) lets you power hardwired circuits — furnace, well pump, hardwired lighting — safely, without the risk of backfeeding the power line. For standby generators, professional installation of the generator and automatic transfer switch is mandatory and costs $1,500–$3,000 beyond the generator price.
