1. Honda EU2200i: Best Overall (Compact)
The EU2200i is the inverter generator other brands get compared against. It is light enough for one person to carry, famously reliable, and clean enough for sensitive electronics. In Bob Vila’s hands-on testing it ran a table saw, a miter saw and then a refrigerator for several hours without trouble. It costs more than rivals with similar output, but owners tend to keep these for a decade or more.
Key specs
- Output: 2,200W peak / 1,800W running
- Fuel: gasoline, 0.95-gallon tank
- Runtime: about 3.2 hours at full load, up to 8.1 hours at 25% load
- Weight: about 47.4 lb
- Start: recoil (no electric start)
- Safety: CO-Minder carbon monoxide shutoff
- App: Honda My Generator (monitoring and remote shutdown)
👍 Pros

👎 Cons
|
What owners say: Owners praise how easily it starts after sitting for months and how quiet it is at campgrounds. The usual complaints are the price and wishing it had a bit more power for RV air conditioners.
2. Westinghouse iGen4500: Best for Home Backup
The iGen4500 hits a sweet spot for storm backup: enough running watts for a fridge, freezer, sump pump and lights at the same time, a big 3.4-gallon tank for overnight runtime, and push-button or key-fob remote start so you don’t have to tug a cord in the cold. It is heavier than a suitcase model, but it rolls on built-in wheels.
Key specs
- Output: 4,500W peak / 3,700W running
- Fuel: gasoline, 3.4-gallon tank with fuel gauge
- Runtime: up to 16 hours at 25% load
- Noise: 62 dBA at 25% load (manufacturer rating)
- Weight: about 105 lb dry
- Start: electric, remote key fob and recoil
- Outlets: TT-30R RV outlet, 20A duplex, 2 USB
- Parallel capable with a second iGen
👍 Pros
|
👎 Cons
|
What owners say: Buyers like the long runtime and the remote fob for starting it from inside. Common gripes are the weight when lifting it into a truck and the lack of a propane option.
3. Champion 4500-Watt Dual Fuel Inverter: Best Dual Fuel
Gas stations can close during a big storm, and stored gasoline goes stale. Champion’s 4500-watt dual fuel inverter also runs on a standard 20-lb propane tank, which stores for years and stretches runtime to as much as 21 hours at light load. It has electric start and an RV-ready outlet, and you can link two units with an optional parallel kit.
Key specs
- Output (gasoline): 4,500W starting / 3,500W running
- Output (propane): 4,500W starting / 3,150W running
- Runtime at 25% load: up to 14 hours on gas, up to 21 hours on a 20-lb propane tank
- Noise: 61 dBA at 23 ft (manufacturer rating)
- Weight: about 103 lb
- Start: electric and recoil
- Outlets: TT-30R, two 20A household, 12V DC
👍 Pros
|
👎 Cons
|
What owners say: Owners like switching to propane during long outages and the price compared with name-brand rivals. A few mention it is bulkier than expected and that the parallel kit costs extra.
4. EcoFlow Smart Generator 4000 (Dual Fuel): Best for Power Station Owners
If you already own (or plan to buy) a large EcoFlow battery, this generator turns it into a hybrid system. It can charge a compatible DELTA Pro 3 directly over DC and start or stop automatically when the battery runs low, so the generator only runs when needed. On its own it is a capable dual fuel inverter with app control and five ways to start it, including a scheduled start.
Key specs
- Output: 3,200W rated on gasoline, 2,900W on LPG; 4,000W peak with X-Boost
- Fuel: gasoline (1.58-gallon tank) or propane
- Runtime (gasoline): about 8 hours at 25% load
- Weight: about 83 lb
- Start: recoil, electric, app, scheduled, or triggered by a connected power station
- App: Bluetooth/Wi-Fi with CO, temperature and fault alerts
- Compatibility: auto start/stop with DELTA Pro 3 (not DELTA Pro Ultra or RIVER series)
👍 Pros
|
👎 Cons
|
What owners say: Owners who pair it with a DELTA Pro 3 love the hands-off automatic recharging. Buyers using it as a standalone generator say rivals offer more watts for the money.
5. Briggs & Stratton Q6500 QuietPower: Best High Output
Most inverter generators top out around 4,000 watts. The Q6500 delivers 5,000 running watts with inverter-quality power, plus a 120/240V locking outlet that a licensed electrician can connect to a transfer switch. Popular Science named it a top pick for home backup and compared its sound to a running dishwasher.
Key specs
- Output: 6,500W starting / 5,000W running
- Fuel: gasoline
- Runtime: up to 14 hours at 25% load
- Weight: about 128 lb, with a telescoping handle and wheels
- Safety: CO Guard automatic shutdown
- Outlets: four 120V 20A, two USB, one 120/240V locking
👍 Pros
|
👎 Cons
|
What owners say: Owners like that it runs a fridge, freezer and furnace together without sounding like a jackhammer. Weight and occasional support headaches are the main complaints.
6. Yamaha EF2200iS: Best Long Runtime (Compact)
Yamaha’s 2,200-watt inverter competes directly with the Honda and edges it on runtime thanks to a larger 1.24-gallon tank. It is a favorite with RVers and tailgaters who want a quiet, dependable unit that can run all evening on one fill-up.
Key specs
- Output: 2,200W peak / 1,800W rated
- Fuel: gasoline, 1.24-gallon tank
- Runtime: up to 10.5 hours at 25% load
- Noise: 57–65 dBA from quarter to rated load (manufacturer rating)
- Weight: about 55 lb dry
- Engine: 79cc OHV four-stroke; 3-year limited warranty
👍 Pros

What owners say: Campers mention that it runs through the night without refueling and stays quiet. Some say it is a little heavy to carry far from the truck.
7. Ford FG2500iS: Best Light-Duty Value
The FG2500iS gives you a bit more running power than the Honda and Yamaha for considerably less money. In Bob Vila’s testing it started in three pulls or fewer every time and stayed quiet enough for electronics and campsite use. It can also be paralleled with a second unit when you need more power.
Key specs
- Output: 2,500W peak / 2,200W running
- Fuel: gasoline
- Weight: about 48.5 lb
- Start: recoil
- Outlets: two 120V 20A, 12V DC, USB-A

What owners say: Owners like the value and the easy starts. Some note the brand support network is smaller than Honda’s or Yamaha’s.
8. Pulsar 2,200W Dual Fuel Inverter: Best Budget
If you want a light, dual fuel inverter for camping or keeping a fridge and phones going during short outages, the Pulsar costs a fraction of the big names. Bob Vila named it the best bang for the buck after it handled heat guns and hair dryers in testing, though it was louder than its advertised rating.
Key specs
- Output (gas): 2,200W peak / 1,800W running
- Output (propane): 2,000W peak / 1,600W running
- Weight: about 46.5 lb
- Start: recoil
- Outlets: two 120V 15A, one USB-A

What owners say: Buyers call it a great value for occasional use. Complaints focus on noise and the fiddly oil fill panel.
How to choose the best inverter generator
- Size it to your loads: Roughly 2,000–3,000W covers camping, tailgating and basic outage needs (fridge, lights, phones). 3,000–4,500W suits RVs and most emergency home use. Go 4,500W+ if you want to run several large appliances at once. Use our power station and generator sizing calculator to add up your running and starting watts.
- Starting vs running watts: Motors in fridges, sump pumps and AC units briefly draw much more power when they start. Make sure the peak rating covers your biggest motor plus everything else running.
- Fuel type: Dual fuel models can run on propane, which stores for years without going stale. Expect slightly lower output on propane.
- Runtime and tank size: Compare runtime at 25% load. A bigger tank means fewer late-night refills.
- Start method: Electric and remote start are easier in the cold but rely on a charged battery. Recoil works anywhere.
- CO protection: Choose a model with an automatic carbon monoxide shutoff, such as Honda CO-Minder or Briggs CO Guard.
- Parallel and RV outlets: Parallel kits let you link two smaller units. A TT-30R outlet plugs straight into most 30-amp RVs.
FAQ
What is the difference between an inverter generator and a regular generator?
An inverter generator converts power electronically to produce a steady, clean sine wave that is safe for electronics, and it throttles the engine to match demand. That makes it quieter and more fuel-efficient than a conventional open-frame generator, which runs at a constant speed.
Can an inverter generator run a refrigerator?
Yes. Most 2,200W units can run a typical home refrigerator, which can need up to about 1,000W for a moment at startup. Check the fridge’s label and the generator’s manual, and avoid running other big loads at the same moment.
Where should I place a generator during an outage?
Always outdoors, never in a garage, basement or porch, and at least 20 feet from the house with the exhaust pointed away from doors and windows. Follow the manufacturer’s instructions and keep working CO alarms inside your home.
Can I connect an inverter generator to my house?
Only through a transfer switch or interlock installed by a licensed electrician. Never backfeed a home through a wall outlet, which can injure utility workers and damage appliances.
