The storm has passed, but the street is still dark. Two houses down, an old open-frame generator roars like a lawn mower that never stops. Out in your own yard, well away from the house, a small inverter generator hums along, the fridge is cold, the Wi-Fi is back and you can still talk on the porch without shouting. That quiet, steady power is why so many people choose an inverter generator.

The best inverter generator for most homes in 2026 is the Honda EU2200i: 1,800 running watts, 48 dB(A) at quarter load, up to 8.1 hours per tank and Honda’s CO-MINDER shut-off. If you want to run a fridge, a sump pump and lights in an outage, step up to the Champion 4500W Dual Fuel Inverter, which runs on gasoline or propane.

Below: seven picks, how to size one, and how to run it safely.

Prices change often. The prices below are the maker’s own published price or list price in October 2026; check the current price before you buy. Where the maker shows no price, we left it out. We researched and compared these generators from maker specs; we did not test them.

DuroMax XP2300iH	1,800 / 2,300	Gas or propane	13 h (1.1 gal)	52 dB	50.6 lb	$649 (maker sale)
Yamaha EF2200iS	1,800 / 2,200	Gas	10.5 h (1.24 gal)	57–65 dB(A) at 7 m (23 ft)	55.2 lb	Check price
Westinghouse iGen2200c	1,800 / 2,200	Gas	12 h (1.14 gal)	As low as 52 dB(A)	47.4 lb	$579 (list)

Noise numbers aren’t measured the same way by every maker. Honda, Champion and Yamaha give a distance (23 feet / 7 meters); Westinghouse and DuroMax don’t on the pages we read, and Generac publishes no decibel figure for the GP3300i. Use them as a rough guide, not a ranking. Westinghouse lists its prices on its own store but showed both models as unavailable to buy there in October 2026.

What makes an inverter generator different

A conventional generator spins its engine at a constant 3,600 rpm to make household power directly. An inverter generator makes raw AC power, turns it into DC, then back into clean AC with steady voltage. Champion describes the result as power with total harmonic distortion (THD) of 3% or less, which is what sensitive electronics like laptops, TVs and furnace control boards prefer. Three things follow from that design:

• Quieter and thriftier. The engine speeds up and slows down with the load instead of running flat out all the time, which saves fuel and cuts noise at light loads.
• Smaller and lighter. A 2,200-watt inverter weighs under 50 lb and you can carry it with one hand.
• Parallel capable. Many models link to a second unit with a parallel kit for more power when you need it.

The trade-off is price per watt and size: most inverter generators top out around 4,000–5,000 watts and give 120 volts only, so they can’t run 240-volt loads like a well pump or central air by themselves. For those, see our best dual fuel generators (bigger open-frame models) or compare both designs in inverter vs conventional generator.

The best inverter generators

1. Honda EU2200i: best overall

The EU2200i delivers 1,800 running watts and 2,200 starting watts from a 0.95-gallon tank. Honda rates it at 48 dB(A) at quarter load and 57 dB(A) at full load, measured at 23 feet, and lists up to 8.1 hours at quarter load (3.2 hours at full load). Its CO-MINDER system shuts the engine off if carbon monoxide builds up around it. It weighs 47.4 lb, connects to a second unit for parallel power, and current units add Bluetooth app control. Honda’s MSRP is about $1,199 (maker’s price, October 2026).

• Good: very quiet at light loads; light; three-year residential warranty; parallel capable.
• Watch out: recoil start only; one 20 A duplex outlet; the highest price per watt here.
• Best for: keeping a fridge, lights, phones and Wi-Fi going quietly, plus camping and tailgating.

2. Champion 4500W Dual Fuel Inverter: best for home backup

This is the size most homes actually need in an outage. On gasoline it gives 3,500 running and 4,500 starting watts; on propane, 3,150 running and the same 4,500 starting. Champion lists up to 14 hours on its 2.3-gallon tank and up to 21 hours on a 20-lb propane tank, both at 25% load, and 61 dB(A) at 23 feet. It has electric start with the battery included, wheels, a 30 A RV outlet (TT-30R), two 20 A outlets and parallel ports. Champion’s CO Shield shuts the engine off when carbon monoxide builds up.

• Good: enough power for a fridge, a sump pump and lights together; propane option for long outages; push-button start.
• Watch out: 99.2 lb, so you’ll roll it, not carry it; 120 V only.
• Best for: home backup where noise matters and you want the option of stored propane.

3. Westinghouse iGen5000DFc: most power

The iGen5000DFc (it replaces the iGen4500DFc) is the biggest inverter here: 3,900 running and 5,000 starting watts on gasoline, 3,500 and 4,500 on propane. Its 3.4-gallon tank gives up to 18 hours at 25% load, and Westinghouse lists up to 22 hours on propane. You get remote, electric and recoil start, a 30 A RV outlet, a 20 A duplex and two USB ports, and an automatic CO shutdown sensor. Westinghouse says the optional parallel kit adds 240 V and makes it interlock and transfer-switch ready. List price on westinghouse.com is $1,299 (October 2026), though the store showed it unavailable there.

• Good: the longest gasoline runtime and most running watts in this list; remote start from the key fob.
• Watch out: 105.8 lb; Westinghouse’s spec table says it is not CARB compliant while an Amazon title says it is, so Californians should check before buying.
• Best for: bigger outage loads with inverter-quiet running.

4. Generac GP3300i with COsense: best value mid-size

The GP3300i sits between the 2,200-watt class and the big inverters: 2,500 running and 3,300 starting watts, with Generac’s PowerRush feature for extra motor-starting help. Generac lists 7 hours at 25% load and 4.5 hours at 50% on its 1.06-gallon tank. The panel is generous for its size: two 20 A duplex outlets, a 30 A twist-lock (L5-30R) and two USB ports. COsense shuts it down if carbon monoxide builds up. Generac’s MSRP is about $939 (maker’s price, October 2026).

• Good: more watts than the 2,200 class at a lower price than Honda; parallel kit available.
• Watch out: no published noise rating; shorter runtime per tank than the others; gasoline only.
• Best for: a fridge plus a window AC or a small pump without the weight of a 100-lb unit.

5. DuroMax XP2300iH: best budget dual fuel

The XP2300iH runs on gasoline (1,800 running / 2,300 starting watts) or propane (1,700 / 2,150). DuroMax lists 13 hours on gasoline and up to 38 hours on propane at 25% load, and 7 and 18 hours at 50%. It has two 20 A outlets, a 30 A twist-lock (L5-30R), USB-A and USB-C, under 3% THD, a parallel cable in the box and DuroMax’s CO Alert shut-off. It’s about $649 on duromaxpower.com (maker’s sale price, October 2026; list $799).

• Good: the lowest price here; very long propane runtime; three-year warranty.
• Watch out: not CARB compliant (DuroMax says it isn’t a 50-state model), so it’s not for California buyers; recoil start.
• Best for: a low-cost backup that can sit ready on propane.

6. Yamaha EF2200iS: best small one for RVs

Yamaha’s EF2200iS matches the Honda on output (1,800 running / 2,200 starting watts) but carries a bigger 1.24-gallon tank, good for up to 10.5 hours at quarter load. Yamaha rates it at 57 dB(A) at quarter load and 65 dB(A) at full load, measured at 7 meters (23 feet). The US model adds a 30 A RV outlet and a 12 V DC outlet next to the 120 V duplex, and a CO sensor that shuts the engine off automatically. It weighs 55.2 lb and has a three-year limited warranty. Yamaha publishes no price.

• Good: RV outlet in a small unit; long runtime per tank.
• Watch out: louder than the Honda on Yamaha’s own figures; recoil start.
• Best for: RV and camper owners who also want outage backup.

7. Westinghouse iGen2200c: lightest budget pick

The iGen2200c gives the same 1,800 running and 2,200 starting watts as the Honda and Yamaha, weighs 47.4 lb, and Westinghouse lists up to 12 hours on its 1.14-gallon tank at 25% load and as low as 52 dB(A). Buy the “c” model: it has the automatic CO shutdown sensor, and the plain iGen2200 does not. Outlets are one 120 V duplex and two USB ports. List price is $579 on westinghouse.com (October 2026), shown unavailable there.

• Good: long runtime for its size; parallel capable; low list price.
• Watch out: only one AC duplex; not CARB compliant.
• Best for: fridge-and-lights backup on a budget.

Also worth a look: the Honda EU3200i (2,600 running / 3,200 starting watts, fuel-injected, Honda MSRP about $2,799) if you want Honda in a bigger size, and the Champion 2500W Dual Fuel Inverter with CO Shield (1,850 W gas / 1,665 W propane, 43.2 lb, 53 dB(A) at 23 ft), the lightest generator we found in the catalog.

How to choose an inverter generator

Start with what you must run, not with the biggest number on the box. Champion’s method: add up the running watts of everything that will be on at once, then add the starting watts of the single biggest motor (fridge, pump, furnace blower). Typical figures from Champion’s wattage chart: a refrigerator runs on 150–400 W and needs 800–1,200 W to start; a 1/2 HP sump pump runs on 800–1,050 W and needs 1,300–2,150 W to start; an LED bulb uses 8–15 W and a modem and router 10–20 W. Check your own appliance labels; they are the real numbers.

What you want to run (Champion chart, upper figures)	Running W	Peak W (running + biggest start)	Size that fits
Fridge 400 + 10 LED bulbs 100 + router 20 + laptop and phones 100 + TV 200	820	820 + 1,200 = 2,020	2,200-W class (Honda, Yamaha, Westinghouse iGen2200c, DuroMax)
All of the above + 1/2 HP sump pump 1,050	1,870	1,870 + 2,150 = 4,020	3,500 W running or more (Champion 4500, Westinghouse iGen5000DFc)

That second row is a worst-case sum (the fridge and pump rarely start at the same moment), but it shows why a 2,200-W generator is a “fridge and lights” machine, and why a sump pump pushes you to the 3,500-W class. For the full method, see what size generator do I need.

• Fuel: dual fuel (gas or propane) is worth it for home backup. Propane stores for years without going stale; the trade-off is a little less power. Our dual fuel guide has the numbers.
• CO shut-off: buy a model with one. CPSC says to look for it, and every pick here has one (Honda CO-MINDER, Champion CO Shield, Generac COsense, Westinghouse CO Sensor, DuroMax CO Alert, Yamaha’s CO sensor). CPSC also points to models certified to PGMA G300-2023 or UL 2201-2023.
• Starting: electric or remote start matters if anyone in the house can’t pull a recoil cord.
• Outlets: a 30 A outlet (TT-30R or L5-30R) lets you run a heavy-duty cord or an RV. Most inverters are 120 V only.
• California: check the CARB label if you live there; several models here are not CARB compliant.
• Connecting to the house: use outdoor-rated extension cords to individual appliances, or have a licensed electrician install a transfer switch or a panel interlock with an inlet box, with a permit where required. Interlock kits must match your panel’s brand and listing. See our transfer switch guide.

Run it safely: carbon monoxide and fuel

A quiet generator still makes carbon monoxide, a gas you can’t see or smell. CPSC says an average of about 100 people in the U.S. die each year from CO poisoning from portable generators, and that it can kill in minutes. The rules from CPSC and CDC are simple and non-negotiable:

• Outdoors only, at least 20 feet from the house, with the exhaust pointed away from windows, doors and vents.
• Never in a garage, basement, crawlspace or shed, even with the door or windows open. CPSC also says not on a porch or in a carport: too close to the house.
• CO alarms on every level of the home and outside sleeping areas, battery-powered or plug-in with battery backup, tested monthly. A CO shut-off on the generator does not replace them; Champion itself says CO Shield is not a substitute for an indoor CO alarm.
• Feel dizzy, sick or weak? Get to fresh air right away and call 911.
• Refuel only when it’s off and cool: CPSC warns that gasoline spilled on hot engine parts can ignite.
• Never backfeed by plugging the generator into a wall outlet. It can electrocute utility workers and neighbors, and it bypasses your home’s circuit protection.
• Rain: CPSC suggests an open, canopy-like cover on a dry surface, never moving the generator indoors or near openings.

Gasoline storage: store fuel outside living areas in labeled, non-glass safety containers, away from fuel-burning appliances like a garage water heater (CPSC). Add a stabilizer when you fill the cans: STA-BIL says its Storage formula keeps gasoline fresh up to 24 months at 1 oz per 2.5 gallons. Use up older cans in your car or mower and refill them, so the gas you store never sits past the stabilizer’s limit, and follow your generator manual’s storage steps between outages.

Inverter generator questions

What is the best inverter generator for a home power outage?

For a fridge, lights and Wi-Fi, a 2,200-watt model like the Honda EU2200i is enough and very quiet. If you also need a sump pump or a furnace blower, choose a 3,500-watt-running class model like the Champion 4500W Dual Fuel Inverter or the Westinghouse iGen5000DFc. Neither size runs 240-volt loads on its own.

Are inverter generators safe for electronics?

Yes, that’s their main strength. They convert power to DC and back to steady AC; Champion describes inverter power as 3% THD or less, and DuroMax lists under 3% for the XP2300iH. That clean power suits laptops, TVs, modems and the control boards in furnaces and fridges.

Can an inverter generator run a refrigerator?

Yes. Champion’s chart puts a refrigerator at 150–400 running watts and 800–1,200 starting watts, well within a 1,800-running, 2,200-starting-watt inverter. Leave headroom for other loads, and remember a closed fridge stays cold for hours, so you can run it in shifts to save fuel.

How far from the house should an inverter generator be?

At least 20 feet, outdoors, with the exhaust pointed away from windows, doors and vents, says CPSC. Quiet doesn’t mean safe: inverter generators still produce carbon monoxide. Never run one in a garage, even with the door open, or on a porch or in a carport, and keep working CO alarms on every level of the home.

Can I connect an inverter generator to my house?

Only through a transfer switch or a panel interlock with an inlet box installed by a licensed electrician, with a permit where required. Most inverters are 120 V only, so check that the switch matches your generator’s outlet. Never plug a generator into a wall outlet: that backfeeding can electrocute utility workers.
