Inverter generators make clean, stable power that’s safe for laptops, phones and RV electronics, and they’re far quieter than old open-frame generators because the engine slows down when you need less power.
We compared the best-selling inverter generators on Amazon for camping, RVs and power outages, from $310 to $1,299. Each has the real price, power, noise and runtime the maker quotes, what buyers report and one honest catch.

Our quick picks
- Best overall (quietest, most reliable): Honda EU2200i, $1299.00
- Best small budget inverter: WEN 2350, $429.00
- Best for RVs with AC: Champion 4000 Dual Fuel, $719.00
- Best value dual fuel: PowerSmart 3800, $469.99
- Cheapest 3,000W+: Oxseryn 4400 (open frame), $309.99
How big do you need? About 2,000 running watts runs a fridge, lights, a TV and phones, or a small RV without the air conditioner. To run a 13,500 BTU RV air conditioner, most people need around 3,000 running watts or two small inverters linked in parallel.
The 6 best inverter generators on Amazon
1. Honda EU2200i Inverter Generator $1299.00
The generator everyone compares against. Honda says it runs at 48 to 57 dB(A), quieter than a normal conversation, and lasts 3.2 to 8.1 hours on its 0.95-gallon tank depending on load.
It has Honda’s My Generator app over Bluetooth and a CO-MINDER sensor that shuts it down if carbon monoxide builds up. Buyers say it starts on the first pull, runs for days and can even power an 11,000 BTU RV air conditioner.
- 2,200W peak, 48 to 57 dB(A)
- 3.2 to 8.1 hours on 0.95 gallons (Honda)
- Bluetooth app monitoring and control
- CO-MINDER carbon monoxide shutdown
The catch: $1,299 is three times the price of the WEN for similar wattage. You’re paying for Honda’s reliability and resale value, not more power.
Best for: Campers and RVers who want the quietest, most dependable small generator.
2. WEN 56235i Super Quiet 2,350W Inverter Generator $429.00
A popular budget alternative to the Honda: 39 pounds, 1,900 running watts, and WEN says it’s about as loud as a normal conversation.
Its fuel shutoff runs the carburetor dry before switching off, which helps the engine last. Buyers say it starts first pull, is surprisingly quiet in economy mode and very fuel efficient; one reports 10 hours on a gallon.
- 1,900 running watts, 2,350 surge
- 39 lb
- Fuel shutoff for longer engine life
- Clean power for electronics
The catch: Buyers are split on power: some run full campers with AC, others say it struggles to keep a steady output near its limit. Don’t plan to run it flat out for hours.
Best for: Tailgates, camping and essentials in an outage on a budget.
3. Champion 4,000W Dual Fuel RV Ready Inverter Generator $719.00
Enough power for an RV air conditioner, with an RV-ready TT-30R outlet and the option to run on gasoline or propane right out of the box.
Champion quotes 64 dBA at 23 feet, up to 10 hours on gas and 25 hours on propane. Buyers say it runs their RVs well, even powering a 30-gallon air compressor, and runs nicely on propane.
- 4,000 starting watts, 3,000 running (gas)
- Up to 10 hours gas, 25 hours propane (Champion)
- TT-30R RV outlet plus household duplex
- CO Shield carbon monoxide shutoff
The catch: At 64 dBA it’s noticeably louder than the Honda, and the parallel kit to link two units is sold separately. There’s also a gas-only version for $639.99 if you don’t need propane.
Best for: RV owners who need to run the air conditioner.
4. PowerSmart 3,800W Dual Fuel Inverter Generator $469.99
Dual fuel and over 3,000 running watts for well under the Champion’s price. PowerSmart says it runs 8 hours at 25% load on its 1.3-gallon tank, or up to 24 hours on a 20 lb propane tank.
It’s 59 dBA at 25% load in Eco mode, with CO sensor, overload and low-oil protection. Buyers say it’s reliable, starts easily, runs quietly and is good value.
- 3,800 starting / 3,300 running watts on gas
- Up to 24 hours on a 20 lb propane tank
- 59 dBA at 25% load (Eco mode)
- CO sensor, overload and low-oil shutdown
The catch: Durability is mixed in Amazon’s summary, with some buyers reporting units dying after about three months. Register the warranty and run it monthly.
Best for: The best price for dual-fuel power at around 3,000 watts.
5. MaXpeedingrods 3,500W Inverter Generator $399.99
A budget 3,000-running-watt inverter with a 30A RV outlet, two 20A household outlets and USB ports.
In Eco mode the maker quotes 8.3 hours at 25% load. Buyers say it’s quiet, light and easy to start, and one reports running it for 20 hours non-stop.
- 3,500 peak / 3,000 running watts
- 30A RV outlet, 2 × 20A outlets, USB
- Up to 8.3 hours at 25% load (Eco)
- EPA compliant, pure sine wave
The catch: It has the lowest rating here (4.0). Buyers are split: some say it runs flawlessly, others say it won’t stay running or only runs a few minutes.
Best for: Budget buyers who need 3,000 watts and accept some risk.
6. Oxseryn 4,400W Open Frame Inverter Generator $309.99
The cheapest generator here, and the most power for the money: 3,400 running watts with an RV port and a 2-gallon tank with a fuel gauge.
The seller quotes up to 14 hours at 25% load in Eco mode. Buyers say it starts first pull and gives up to 12 hours on a full tank.
- 4,400 peak / 3,400 running watts
- Up to 14 hours at 25% load (seller)
- 2 × 120V outlets, 12V DC and RV port
- Fuel gauge, Eco mode
The catch: It’s an open-frame design: under 72 dBA from 23 feet, much louder than the enclosed inverters here, and buyers are split on noise. Reliability is also mixed, with one failing after about six weeks.
Best for: Home backup where noise matters less than price.
Inverter generator vs portable power station
| Inverter generator | Power station | |
|---|---|---|
| Runs for | Hours to days with fuel | Until the battery is empty |
| Noise | 48 to 72 dBA | Near silent |
| Indoors | Never | Yes |
| Best for | RV AC, long outages | CPAP, phones, small appliances |

Generator safety
- Never run a generator indoors, in a garage or near open windows: carbon monoxide can kill in minutes.
- Keep it at least 20 feet from the house with the exhaust pointing away.
- Use a transfer switch or inlet installed by an electrician to power house circuits; never backfeed a wall outlet.
- Let it cool before refuelling.

Frequently asked questions
What is the best inverter generator?
The Honda EU2200i ($1,299) is the quietest and most proven. For value, the WEN 56235i ($429) gives similar small-generator power for a third of the price, and the Champion 4000 dual fuel ($719) can run an RV air conditioner.
What size inverter generator do I need for an RV?
Around 3,000 running watts to run a 13,500 BTU air conditioner, like the Champion 4000 or PowerSmart 3800. A 2,000W unit handles an RV without the AC.
Are inverter generators quiet?
Enclosed models run around 48 to 64 dBA at 23 feet, roughly conversation level. Open-frame designs like the Oxseryn are much louder.
Is dual fuel worth it?
Yes for outages: propane stores for years without going stale and is easy to buy. It gives slightly less power than gasoline.
Can I run an inverter generator in the rain?
Not unprotected. Use a purpose-made generator tent or cover that keeps it dry while leaving plenty of airflow, and never move it into a garage.
