Carbon monoxide: where you run it matters

Popular Mechanics says never to run a generator in a garage or shed, even with the door open, and to keep it at least 20 feet from the house, including windows and doors, with the exhaust pointed away. Wirecutter cites the CPSC's figure of roughly 85 deaths a year from portable-generator CO poisoning, and warns that a CO shutoff doesn't remove the danger.

If you just want an answer

What portable generator owners complain about most

  1. Fuel tanks and runtime. Small gas tanks, runtimes that vary or fall short, gas-only engines and missing fuel gauges come up for five models.
  2. Heavy. Larger inverters and open-frame generators are heavy to move, which four of the eight draw complaints about.
  3. Not enough power — or too pricey. Small inverters can't run a home's big loads, while the models that can are expensive.
  4. Starting and running problems. Hard starts, pull starts and units that won't stay running are reported for some models.
  5. Noise and regional limits. Open-frame models are loud, and one model can't be sold in California.

Honda

Honda EU7000iS

$$$InverterScore 4.5/5
6%
of Amazon ratings are 1–2 stars
(checked 2026-10-10)
Very small sample (35 ratings).

A premium, very quiet 5,500-watt inverter with Honda build quality, a Bluetooth app, 240-volt output and a CO shutoff. Popular Mechanics measured about 70 dB at 15 feet under a 60% load. It costs about $4,899, weighs 263 pounds and runs on gasoline only.

Recalls (CPSC): CPSC recall 23-251 (2023-08-03): about 250 EU7000is generators (serials EEJD-1364963 to EEJD-1366026) because the fuel filler cap may not seal and can leak fuel or vapor (fire hazard); no injuries. Remedy: free repair at a Honda dealer.

Power (gasoline): 5,500 running / 7,000 starting watts

CO shutoff: Yes: a CO monitor shuts the generator down if dangerous CO levels are detected nearby (Popular Mechanics)

Top complaints

What owners love

  • Remarkably quiet

    About 70 dB at 15 feet and near 65 dB at 20 feet with a 60% load, even in standard throttle (Popular Mechanics).

  • Built to last

    Stamped metal and impact-resistant composite casing, and an engine Popular Mechanics expects to last many years with maintenance. Wirecutter says Honda generators are known for quality and reliability.

  • Useful app and outlets

    The Bluetooth app turns it on and off, shows fuel, oil and output, and sends service reminders. GFCI outlets, a 30-amp 120-volt outlet and a 30-amp 120/240-volt outlet for a transfer switch (Popular Mechanics).

Good for
  • Quiet home backup through a transfer switch
  • Buyers who want Honda reliability
  • Monitoring power use from your phone

Westinghouse

Westinghouse iGen5000DFc

$$Dual-fuel inverterScore 4.2/5
5%
of Amazon ratings are 1–2 stars
(checked 2026-10-10)
Sample under 1,500 ratings (1,165).

Wirecutter's top pick: a closed-frame dual-fuel inverter with 3,900 running watts, a remote-start key fob, CO shutoff and up to 18 hours at 25% load, for about $1,000. It's over 100 pounds, can't be sold in California, and Wirecutter chose it from research rather than hands-on testing.

Recalls (CPSC): No CPSC recall found for the iGen5000DFc (checked 2026-10-11). An earlier Westinghouse recall on 2020-09-16 (CPSC 20-185, about 7,500 units) covered iGen4500DF and WGen5300DFv generators made October-December 2019 for fuel leaks.

Power (gasoline): 3,900 running / 5,000 starting watts

CO shutoff: Yes: CO shutoff (Wirecutter); the listing says the engine has a CO sensor

Top complaints

  • Not sold in California

    Wirecutter's one major drawback: it isn't CARB-compliant, and there's no California version.

  • Hits its limit with several big loads

    Wirecutter says it reaches its limit running larger items like a fridge, freezer and space heater all at once, and probably can't handle central AC or a clothes dryer.

  • Heavy

    A little over 100 lb without gas, about average for its size, though it has two top handles and a telescoping handle (Wirecutter).

What owners love

Good for
  • Home backup for a fridge, freezer and lights
  • Starting from indoors on bad-weather days
  • Long runs on one tank

Scores (tap for why)

  • Power for your needs3.5
    Why 3.5?3,900 running / 5,000 starting watts on gas, 3,500 / 4,500 on propane: enough for essentials and many appliances, but not all at once (Wirecutter).
  • Quietness4.5
    Why 4.5?52 dB(A) rating, among the lowest Wirecutter saw, with an eco mode. Amazon owners praise its quiet operation.
  • Easy start & fuel5.0
    Why 5.0?Electric start, a remote-start fob, gas or propane and an up-to-18-hour gas runtime (Wirecutter).
  • CO safety features4.0
    Why 4.0?CO shutoff (Wirecutter) and a CO sensor on the engine (Amazon listing).
  • Reliability4.0
    Why 4.0?Consistently stellar retailer reviews (Wirecutter), strong Amazon feedback, and a 3-year warranty that Wirecutter contrasts with Predator's 90 days.

What experts say

  • Wirecutter (NYT): Top pick (updated 2025-07-30, based on research and past testing, not yet hands-on): versatile, quiet and well-equipped for the price, but not sold in California.

DuroMax

DuroMax XP11000iH

$$$Dual-fuel inverterScore 4.2/5
18%
of Amazon ratings are 1–2 stars
(checked 2026-10-10)
Small sample (227 ratings), and the listing pools other DuroMax models.

Popular Mechanics' best home generator overall: a 9,000-watt dual-fuel inverter that's as loud as a dishwasher (61 dB at 20% load), with remote start, a battery tender and CO shutoff. It weighs 216 pounds and costs about $2,499, and its Amazon listing shows a high share of 1-star ratings.

Recalls (CPSC): No CPSC recall found for DuroMax generators (SaferProducts.gov recall search for 'generator', checked 2026-10-11).

Power (gasoline): 9,000 running / 11,000 starting watts

CO shutoff: Yes: CO shutoff (Popular Mechanics); the Amazon listing calls it CO Alert, which turns the generator off at unsafe CO levels

Top complaints

  • Heavy

    Popular Mechanics' only con: at 216 lb it isn't easy to carry, though it rolls on flat, paved ground.

  • High share of 1-star ratings

    16% of its Amazon ratings are 1 star, but the listing has only 227 ratings and pools other DuroMax models, and no summary of complaints was shown.

What owners love

  • Surprisingly quiet for whole-home power

    61 dB at a 20% load, about as loud as a dishwasher, and quieter still on propane. Popular Mechanics says it may be the quietest whole-home-capable gas generator it has tested.

  • Ready when you need it

    Remote start, an integrated battery tender and a display showing hours, load and voltage. It arrives with wheels and handles attached (Popular Mechanics).

  • Lots of outlets

    120/240-volt 50- and 30-amp outlets plus four 20-amp outlets, a 7.1-gallon tank, and parallel capability (Popular Mechanics).

Good for
  • Whole-home backup through a transfer switch
  • Quiet power at high wattage
  • Generators that sit for months between outages

Honda

Honda EU2200i

$$InverterScore 3.8/5
3%
of Amazon ratings are 1–2 stars
(checked 2026-10-10)
Sample under 1,500 ratings (1,350) for the Companion listing. The standard EU2200i listing (B079YF1HF6, 3,232 ratings) also shows 3%.

Popular Mechanics' best overall portable generator and Bob Vila's camping pick: light (about 47 lb), very quiet, clean power and Honda's CO-MINDER shutoff. At 1,800 running watts with a tank under a gallon, it isn't a home-backup machine, and it costs about $1,199.

Recalls (CPSC): CPSC recalls of earlier units: 2019-03-20 (CPSC 19-088), about 200,000 EU2200iTA/iTA1/iTA2 and EB2200iTA generators because fuel could leak from the fuel valve (fire and burn hazard), and 2020-03-17 (CPSC 20-090), about 340,000 EU2200i, EU2200i Companion, EU2200i Camo and EB2200i generators (serials EAMT-1000001 to EAMT-2098790) because saltwater could short-circuit the inverter (10 fires reported, no injuries). Remedy in both: free repair at a Honda service dealer.

Power (gasoline): 1,800 running / 2,200 starting watts

CO shutoff: Yes: CO-MINDER monitors CO and shuts the generator down before detected levels near it become dangerously high (Honda)

Generac

Generac iQ3800 Dual Fuel

$$Dual-fuel inverterScore 3.8/5
25%
of Amazon ratings are 1–2 stars
(checked 2026-10-10)
Very small sample (31 ratings), 25% 1-star and 0% 2-star.

Popular Mechanics' pick for sensitive electronics: one of the quietest it has tested at this size (61 dB at 25 feet, half load), with easy electric start, clean power and a CO shutoff. It costs more than a standard generator of similar capacity, and the dual-fuel Amazon listing has few ratings, with several owners saying it won't stay running.

Recalls (CPSC): No CPSC recall found for the iQ3800 (checked 2026-10-11). Generac's 2026-04-16 recall (CPSC 26-407, about 149,400 units) covers some GP-series open-frame models whose carburetors can leak fuel, not this model.

Power (gasoline): 3,000 running / 3,800 starting watts

CO shutoff: Yes: automatic CO shutoff that won't let it restart until the area is clear (Popular Mechanics); Generac calls it COsense

Westinghouse WGen9500DF

$$Dual-fuel open-frameScore 3.4/5
3%
of Amazon ratings are 1–2 stars
(checked 2026-10-10)

A lot of generator for about $999: 9,500 running watts, 30- and 50-amp 240-volt outlets for a transfer switch, and electric, remote and recoil start. Bob Vila picked it as best dual-fuel. It's a loud (74 dB) open-frame unit of about 210 pounds, and none of our sources list a CO shutoff.

Recalls (CPSC): No CPSC recall found for the WGen9500DF (checked 2026-10-11). An earlier Westinghouse recall on 2020-09-16 (CPSC 20-185) covered iGen4500DF and WGen5300DFv units made October-December 2019.

Power (gasoline): 9,500 running / 12,500 starting watts

CO shutoff: Not listed: none of our sources mention a CO shutoff on this model (Popular Mechanics lists a low-oil shutoff)

Top complaints

Champion 4000-Watt Dual Fuel Inverter

$$Dual-fuel inverterScore 3.3/5
8%
of Amazon ratings are 1–2 stars
(checked 2026-10-10)
Sample under 1,500 ratings (693).

Wirecutter's pick for lighter needs: a closed-frame, dual-fuel inverter with CO Shield at about 50 pounds and around $719. It has about 1,000 fewer watts than mid-size picks, so appliances may need to run one at a time, and it runs about 10 hours per tank at 25% load.

Recalls (CPSC): No CPSC recall found for Champion generators (SaferProducts.gov recall search for 'generator', checked 2026-10-11).

Power (gasoline): 3,000 running / 4,000 starting watts

CO shutoff: Yes: CO Shield carbon monoxide auto shutoff (Amazon listing; Wirecutter says it has CO detection)

Top complaints

  • Limited power

    Wirecutter says appliances may need to run one at a time and it won't handle larger items like big window AC units. It doesn't recommend bothering with a panel hookup.

  • Shorter runtime

    About 10 hours at 25% load versus 18 hours for Wirecutter's top pick, because of the smaller engine and tank (Wirecutter).

  • Pull start

    The Amazon listing for the 201050 describes it as recoil start, while Wirecutter says all its picks have electric start.

What owners love

Good for
  • Camping, tailgating and RVs
  • Minimal home backup with extension cords
  • Buyers who want CO shutoff on a budget

Scores (tap for why)

What experts say

  • Wirecutter (NYT): Best for versatile portability (updated 2025-07-30, chosen on research, not yet tested): a relative bargain with CO detection and dual fuel, but less capacity and a 10-hour runtime.

Sample under 1,500 ratings (531).

Popular Mechanics' budget pick: a 49-pound dual-fuel inverter with a 30-amp RV outlet, USB ports and a CO shutdown sensor for well under $700. The 1.5-gallon tank runs only about five hours at half load on gas, and Amazon owners are split on how easily it starts.

Recalls (CPSC): No CPSC recall found for WEN generators (SaferProducts.gov recall search for 'generator', checked 2026-10-11).

Power (gasoline): 2,900 running / 3,600 starting watts

CO shutoff: Yes: WEN's Watchdog CO shutdown sensor turns the generator off if dangerous CO levels are detected (Amazon listing, Popular Mechanics)

Top complaints

  • Small gas tank

    Popular Mechanics' only listed con: the 1.5-gallon tank gives about five hours at half load before refilling, though a 20-lb propane tank can run it up to 14 hours.

  • Hard starting for some owners

    Amazon's summary says starting difficulty gets mixed feedback (69 mentions): some find it easy, others say it takes several pulls.

  • Run time varies

    Amazon's summary says run time is mixed (56 mentions), with some owners getting about 4 hours and others saying it lasted only half an hour.
