The WEN DF360iX 3600-watt dual fuel inverter is the best all-round portable generator in this guide for most households that want quiet power for a few essentials, and the Westinghouse 6500 Watt Dual Fuel is the better choice if you want to run more of the house through a transfer switch. This guide ranks the best portable generators by price tier and size rather than by calendar year, because year-based lists go stale quickly and a model that topped a 2015 or 2019 list may no longer be sold. You will find a comparison table, seven main picks across budget, mid-range and premium tiers, a worked wattage example, and a safety section you should read before you buy.

We did not personally use these generators. This guide is research-based: it draws on product listing specifications, manufacturer information, and safety guidance from the U.S. Consumer Product Safety Commission (CPSC). Where a spec is not stated in the listing, we write “not listed” and suggest checking the owner’s manual. We do not quote prices because they change; tiers are relative.

Why “Best Portable Generators 2015, 2019, 2021” Lists Go Stale

Many people search for the best portable generators by year, such as 2014, 2016, 2020 or 2022. The reasoning is understandable: you want the latest model. But a year label tells you less than you think. Manufacturers refresh models on their own schedule, older units are discontinued, and safety standards change. A newer model is not automatically better, and an older model may still be a perfectly good value if parts and support are available.

What actually changes from year to year is worth checking instead:

  • Carbon monoxide protection. The CPSC recommends generators with a CO shut-off feature, and notes that models certified to the PGMA G300-2023 and UL 2201-2023 standards include CO safety technologies. A model listed as having a CO sensor or shut-off is a meaningful upgrade over an older one without it.
  • Fuel options. Dual fuel (gasoline and propane) units are now common in the mid-range. Propane stores longer and burns cleaner than old gasoline, which helps for standby use.
  • Inverter technology. Inverter generators produce cleaner power for electronics and run quieter than traditional open-frame units, and more brands now offer them at lower cost.
  • Emissions rules. Some models are sold only in certain states. Check that a generator is compliant where you live.

So instead of choosing by year, choose by wattage need, fuel, noise tolerance, and safety features. The sections below organize picks that way.

How Much Wattage Do You Need? A Worked Example

Add up the running watts of everything you want to power at once, then check the largest starting (surge) wattage of any motor load. Appliance nameplates list real numbers; the table below shows typical ranges so you can plan. These are illustrative; always read your own labels.

Appliance Typical running watts Typical starting watts
Refrigerator About 100 to 250 About 600 to 1,200
Sump pump (1/3 hp) About 400 to 800 About 1,300 to 2,000
Gas furnace blower About 300 to 800 Higher briefly; check the label
LED lights (several) About 50 to 100 Same as running
Phone and laptop charging About 50 to 150 Same as running
Window air conditioner About 500 to 1,500 Often 2 to 3 times running

Example: a fridge (200 running, 1,000 starting), a sump pump (600 running, 1,800 starting), a few lights and chargers (200 total) adds up to 1,000 running watts. The two motors start one at a time, so the worst-case surge is about 1,800 plus the 400 already running, around 2,200 watts. A 2,350 to 3,600 watt inverter generator would cover that with room to spare. Add a window air conditioner (1,000 running, 2,500 starting) and your worst case rises past 3,500, so you would move up to a 4,000 to 6,500 watt model. Plan to stay under about 80 percent of the continuous rating for long runs.

Peak watts and running watts are different numbers. A listing that says “4650 Peak Watt” gives you the short surge capability, not what the unit can sustain. Always check the running (rated) wattage in the manual.

1. WEN DF360iX 3600-Watt Dual Fuel Inverter: Best Overall

  • 3600 watts, inverter design
  • Runs on gasoline or propane (dual fuel)
  • RV-ready outlet per the listing
  • Fuel shut-off and a CO Watchdog feature
  • Running watts, tank size and runtime: not listed in the title

Best for: camping, tailgating, and covering essentials during an outage. Skip if: you want to power a central air conditioner or an electric range.

This is the kind of generator that fits most people’s real needs: enough capacity for a refrigerator, lights, a few electronics and a small appliance, with the quieter operation inverter generators are known for. Dual fuel is a practical advantage because propane can be stored for years in sealed cylinders without the stale-fuel problems that gasoline has. The CO Watchdog feature in the listing is the sort of safety function the CPSC recommends looking for, though no sensor replaces the rule of running the generator outdoors and far from the house.

Pros: dual fuel; inverter output for electronics; CO feature; RV-ready; fuel shut-off. Cons: limited capacity for large loads; propane output is typically a bit lower than gasoline output, so check the manual for the propane rating.

2. Westinghouse 6500 Watt Dual Fuel: Best for Home Backup

  • 6500 watts per the listing (running versus peak rating not stated in the title)
  • Dual fuel: gasoline and propane
  • Transfer switch ready outlet and RV-ready 30A outlet
  • CO sensor

Best for: homeowners who plan to install a transfer switch and run several circuits. Skip if: you want a quiet campsite generator; open-frame units are louder.

A “transfer switch ready” outlet means the generator has the locking outlet that connects to a transfer switch or power inlet box. That setup, installed by a licensed electrician, is the safe way to feed a home’s circuits. It lets you power selected circuits without extension cords running through windows and, critically, prevents back-feeding the utility line, which can injure line workers. Never plug a generator into a wall outlet.

The 30A outlet fits RV hookups, and the CO sensor listed is a plus. Confirm the running wattage and the propane output on the manufacturer spec sheet, because the title gives only the headline number.

Pros: larger capacity; dual fuel; transfer-switch ready; CO sensor. Cons: loud; heavy; open-frame power is less clean than an inverter’s for sensitive electronics.

3. Champion 4000-Watt Dual Fuel Inverter: Best Premium-Brand Mid-Size

  • 4000 watts, inverter, dual fuel
  • RV-ready, with LPG hose included per the listing
  • Recoil start, parallel ready
  • Free 3-year warranty per the listing

Best for: buyers who value an established brand and a longer warranty. Skip if: you want push-button electric start.

The warranty is the most distinctive item here. For a machine you may leave in the garage for months between uses, a longer warranty and a recognizable service network matter more than a few extra watts. Parallel ready means you can link a second compatible unit later to double capacity, which is a practical upgrade path for a growing set of needs.

Pros: brand support and warranty; inverter power; dual fuel; parallel capability. Cons: premium purchase cost; recoil start only.

4. WEN 56235i 2350-Watt Inverter: Best Small and Quiet

  • 2350 watts, gasoline inverter
  • Fuel shut-off, described as ultra lightweight
  • Super-quiet design per the listing; decibel figure not listed in the title

Best for: camping, small RV loads, running a few appliances in an outage. Skip if: you need to power a well pump or a window air conditioner.

At this size, portability counts as much as output. A smaller inverter is easier to carry, uses less fuel at light loads, and is easier on the neighbors. If your outage plan is a refrigerator, lights, a modem, and phone chargers, 2,000 to 2,500 watts is often enough, and you will rarely resent the lower capacity.

Pros: quiet and light; clean power for electronics; fuel shut-off. Cons: limited capacity; gasoline only.

5. Westinghouse 4650 Peak Watt Portable: Best Budget Open-Frame

  • 4650 peak watts
  • RV-ready 30A outlet
  • Gas powered
  • CO sensor in the listing
  • Running watts: not listed in the title

Best for: a basic backup unit for a few essentials at a modest cost. Skip if: you need quiet running or a long list of features.

A budget open-frame generator trades noise and power quality for value. It is a reasonable choice for a work site, a garage, or an outage kit if you know your loads are modest. The CO sensor is the standout; at this tier it is not guaranteed. Remember the peak-versus-running gap: the unit’s sustained output will be below the headline number.

Pros: low cost; CO sensor; RV outlet. Cons: loud; peak figure inflates the headline; gas only in this version.

6. Oxseryn 4400-Watt Inverter (Open Frame): Best Watts for the Money, With Caveats

  • 4400 watts, inverter design in an open frame
  • ECO mode and RV-ready 30A outlet per the listing
  • Gas powered

Best for: shoppers who want the most nominal capacity at a low price. Skip if: parts availability and long-term service matter to you.

The cost-per-watt ratio can be attractive from lesser-known brands. The caution is practical rather than a verdict: check the warranty terms, whether parts are available, and whether the unit is compliant in your state. A lower price on a generator you cannot get serviced is a poor trade if you need it during a storm.

Pros: high nominal wattage for the cost; ECO mode; RV outlet. Cons: brand support unclear; specs beyond the title not listed here.

7. Westinghouse 12500 Watt Dual Fuel: Best Large Dual Fuel

  • 12500 watts per the listing (rating type not stated)
  • Dual fuel with remote electric start
  • Transfer switch ready

Best for: larger homes with a transfer switch installed. Skip if: you only need a few circuits or you cannot store a heavy unit.

A generator in this class can run a well pump, a furnace blower, a refrigerator and more, depending on your load calculation and whether a licensed electrician sets up the transfer switch. It will also burn considerable fuel, so plan for fuel storage and for refueling safely only when the engine is off and cool. Not a good fit if you want something you can carry to a campsite.

Pros: large capacity; remote start; dual fuel. Cons: heavy; loud; fuel use at high loads.

How We Chose

We started with the generators in the site store, covering gasoline, dual fuel and inverter designs from small to large. We read the specifications each listing states, including wattage, fuel type, outlet types and safety features such as CO sensors or shut-offs. We used CPSC guidance for safety information and kept brand repeats to a minimum. Where a listing gave a peak rating but no running rating, we say so. We did not personally use these products and we do not claim rankings by year or sales.

Buying Guide

Start with running watts, not peak

Add the running watts of everything you plan to use together, then add the biggest surge from a motor load. Choose a generator whose running rating is at least 20 percent above your total. Undersizing leads to overloads and tripped breakers.

Pick a fuel type for how you will store it

Gasoline is easy to find but degrades in a few months without stabilizer. Propane stores indefinitely in cylinders and burns cleaner. Dual fuel gives you both. Natural gas needs a hookup and a tri-fuel unit or a standby generator. If your plan is an outage kit that sits for years, propane capability is a real advantage.

Choose inverter or open frame

Inverter generators run quieter, adjust engine speed to the load for better fuel use, and deliver cleaner power for laptops and TVs. Open-frame generators cost less per watt and can be larger, but they are louder and produce less refined power. For camping and neighborhood use, inverter is generally worth the premium.

Look for built-in safety features

A CO sensor or automatic shut-off is the most valuable safety feature a modern generator can have. Look for it in the spec list, and check whether the model is certified to the current standards the CPSC mentions, PGMA G300-2023 and UL 2201-2023. It does not replace safe placement.

Plan the connection

For home backup, ask a licensed electrician about a transfer switch or power inlet box rated for your generator’s output. The generator should never be connected to your home wiring through a wall outlet.

Safety: Where and How to Run a Portable Generator

  • Run the generator outdoors only, at least 20 feet from the house, with the exhaust pointed away from windows, doors and vents, as the CPSC advises.
  • Never run one in a garage, basement, crawlspace, shed or on a porch, even with doors open.
  • Install battery-operated or battery-backup CO alarms outside sleeping areas and on each floor, and test them monthly.
  • Let the engine cool before refueling, and store fuel in approved containers away from the generator.
  • Keep it dry; use a rated canopy or tent made for generators, which handles weather but does nothing to make exhaust safe.
  • Follow the owner’s manual for clearances. If the manual and the CPSC differ, follow the more cautious guidance.

Frequently Asked Questions

What is the best portable generator?

There is no single best; the right one depends on your wattage need. For typical household essentials, a 3,000 to 4,000 watt inverter such as the WEN DF360iX or the Champion 4000 is a sensible target. For a transfer switch setup, look at 6,500 watts and up.

What is the best portable gas generator?

For gasoline-only use, the WEN 56235i suits small loads, and the Westinghouse 4650 Peak Watt suits a basic budget backup. If you want fuel flexibility, a dual fuel model costs a bit more but adds propane.

What is the best portable electric generator for camping?

If by “electric” you mean battery, power stations are a different category, and this site covers them separately. For a fuel-powered generator for camping, a small inverter in the 2,000 to 3,600 watt range is typically best because of weight, noise and clean power.

What is the best mini portable generator?

For small loads such as phones, lights and a laptop, the PowerSmart 1200-watt or the GENMAX GM2000i is in the right class. Do not expect them to run a refrigerator and other motor loads together.

Do older models like a 2012 or 2016 generator still make sense?

They can, if they are well kept and parts are available, but older models are less likely to have CO shut-off features. Check for those safety features before buying anything used.

Do I need a transfer switch?

If you want to power household circuits directly, yes. A transfer switch or inlet box installed by a licensed electrician is the safe method. If you only plan to run extension cords to a few appliances, you do not need one.

How much does a generator cost to run?

It depends on load and fuel price. Run time at half load is usually listed by the maker; multiply tank size by the hours per tank to estimate fuel use, and compare with the listing figure. We do not quote fuel costs because they vary.

Which One Should You Buy?

If you want one generator for camping and outages, choose the WEN DF360iX. For a home with a transfer switch, the Westinghouse 6500 Watt Dual Fuel is the more capable option. Pick the Champion 4000 if warranty and brand support matter, the WEN 56235i if weight and noise matter most, and the Westinghouse 4650 Peak Watt if budget does. Choose the Westinghouse 12500 only if your load calculation requires it. Whatever you buy, read the manual, buy CO alarms, and keep the unit outdoors and well away from the house.
