The Best Inverter Generators
The best inverter generators compared — quiet, fuel-efficient, clean power for sensitive electronics — with picks by watts, noise, parallel capability and runtime.
An inverter generator makes clean, stable power that’s safe for laptops, phones and TVs, and it runs quiet and fuel-efficient because the engine throttles with the load. That’s why inverters own the RV, camping and quiet-home-backup market. Here are the picks from a lightweight camping unit to a whole-home-essentials inverter.
| Model | Best for | Watts | Notes |
|---|---|---|---|
| Honda EU2200i | Best quiet benchmark | 1,800 running / 2,200 peak | The quiet, reliable standard for camping and RVs (~48–57 dB). Premium price. |
| Westinghouse iGen4500 | Best for RV / mid-size | 3,700 running / 4,500 peak | Runs an RV AC and essentials, with remote start and a readout. |
| Champion 2500-watt inverter | Best value / portable | 1,850 running / 2,500 peak | Light, affordable, quiet — a fridge and electronics on the go. |
| Westinghouse WGen9500DF / Champion dual-fuel inverter | Best for home essentials | 7,500–9,500 running | Large (often dual-fuel) inverter to cover a home’s essentials cleanly. |
How to choose an inverter generator
- Watts. Camping/electronics: 2,000–2,500 W. Fridge + essentials: 3,500–4,500 W. Home essentials: 7,500–9,500 W. Size it with the sizing calculator.
- Noise. Inverters run ~50–60 dB — check the rating if you’ll use it at a campground or in a neighborhood.
- Parallel capability. Two smaller inverters can often be linked to start an RV AC without buying one big unit.
- Fuel. A dual-fuel inverter adds propane flexibility.

Frequently asked questions
What is an inverter generator?
An inverter generator produces electricity, converts it to DC and then back to clean, stable AC — so its power is safe for sensitive electronics like laptops, phones and TVs. It also runs quieter and more fuel-efficiently than a conventional generator because the engine throttles up and down with the load instead of running flat-out. That’s why inverters dominate the RV, camping and quiet-home-backup market.
What is the best inverter generator?
For quiet home backup and RVs, the best inverter generators include the Honda EU2200i (the quiet benchmark), the Westinghouse iGen4500 and Champion’s inverter line for value, and larger dual-fuel inverters like the Champion or Predator 9500 for whole-home essentials. The right pick depends on the watts you need and your budget — a 2,000–2,500 W inverter suits camping, while 4,500–9,500 W covers a house.
Are inverter generators worth the extra cost?
If you’ll power electronics, camp or need quiet operation, yes — the clean power protects sensitive devices and the low noise (around 50–60 dB) is campground- and neighbor-friendly. For a purely functional whole-house backup on a budget, a conventional generator gives more watts per dollar. Many buyers pick an inverter for the quiet and clean power even at a premium.
How many watts of inverter generator do I need?
For camping or a few electronics, a 2,000–2,500 watt inverter is plenty and stays light and quiet. To run a refrigerator plus essentials, step up to 3,500–4,500 watts. For a home’s full essentials including a well or sump pump, a 7,500–9,500 watt (often dual-fuel) inverter is the target. Size it precisely with the generator sizing calculator.
