Camping Generators: Verified Models by Size and Fuel

A camping generator has to be light enough to lift into the car, quiet enough for a campground and big enough for what you plug in. This guide sorts the models in our comparison tool into those groups, using the figures each maker publishes, and says where a figure is missing. Specifications were retrieved from manufacturer pages and manuals between 2 and 5 November 2026.

Start with what you will plug in

List the devices, add their running watts, and leave room for any that surge at start-up. The appliance wattage chart, size calculator and load calculator do the sums. Running watts are the figure to size against. Peak watts are a short surge rating.

Small inverter generators: phones, laptops, lights, a fan

• Weight is the gap. The Honda EU2200i is 46.5 lb and the Westinghouse iGen2800 is 46.3 lb. The Yamaha EF2200iS is 55.2 lb.
• Run time is stated at 1/4 load. That is 8.1 hours for the Honda, 10.5 for the Yamaha and 12 for the Westinghouse. The Honda runs 3.2 hours at its full 1,800 W, and Honda is the only one of the three that publishes a full-load figure.
• Price. Westinghouse states 529 USD for the iGen2800. Honda and Yamaha state none on the pages we used.

Mid-size generators: an RV, a small air conditioner, cooking appliances

• Champion 100809. 3,000 running watts at 48.1 lb. It has a TT-30R RV outlet and CO Shield shutdown, but Champion says it is not recommended for emergency home backup, and it has recoil start only.
• Champion 201050. The dual fuel version of that class, at 51.8 lb.
• Yamaha EF3000iS. 2,800 running watts, 54.5 dBA and 18.6 hours at 1/4 load. The weight is 136 lb for the iS and 156 lb for the iSEB, so check which one you are buying. No price is stated.
• Westinghouse iGen5000DF. 3,900 running watts on gasoline, 52 dBA, remote and electric start, at 104.7 lb and 1,199 USD. It lists no CO sensor.

An air conditioner is the usual limit. Check the unit’s starting watts before you rely on any of these. Our quiet camping guide compares noise in more detail.

Dual fuel: propane for the campsite

A dual fuel generator runs on gasoline or propane, so a 20 lb cylinder can stand in for a fuel can. Propane output is lower than gasoline output on every model we list, so size against the propane figure if you plan to use it. These are heavier than the inverters above: 92.6 to 120 lb. See the propane guide and the dual fuel RV guide for run times and cautions.

Battery power stations: no engine, no exhaust

A battery unit such as the EcoFlow Delta 2 has no fuel, exhaust or engine noise, and EcoFlow lists solar charging of up to 500 W. The trade-off is capacity: its 1,024 Wh runs a 1,000 W load for about an hour, and some regional EcoFlow pages list a 950 Wh variant. It suits phones, laptops and lights, not an air conditioner. We have only one battery unit in the database so far.

What to check before you buy

• Noise. Compare distances as well as decibels. Champion states 23 ft, Cummins Onan 10 ft at half load, and Yamaha and Westinghouse state none on the pages we used.
• Weight. Carrying a 100 lb unit from a car is a different job from carrying a 46 lb one.
• Outlets. RV hookups use a TT-30R outlet, which the Champion 100809 and 201050 and the Westinghouse iGen5000DF list.
• CO protection. The Champion 100809 lists CO Shield and the Westinghouse iGen models list no CO sensor. We have no CO figure for the Honda.
• Warranty. Three years is typical in the database. Westinghouse gives 1 year for commercial use.

Camping safety

• Never run a generator inside a tent, camper, vehicle or garage. The US Consumer Product Safety Commission says to keep it at least 20 ft from doors, windows and vents. See the placement guide for how far to put it from a building.
• Read the full safety guide.
• Check the campground’s rules and quiet hours. We have not sourced any park’s generator policy, so ask the campground.
• Store and carry fuel as the manual says. See the maintenance guide for oil checks before a trip.

What we could not verify

• Prices. Honda, Yamaha and Champion state none on the pages we used.
• Fuel economy in gallons per hour. Run times above are manufacturer figures at stated loads, not our tests.
• Campground generator rules and propane shelf life. We have no source for either.
• Reliability. We have no data for any brand.

Frequently asked questions

What size generator do I need for camping?

Add the running watts of everything you will use together. Phones, laptops and lights fit the 1,800 W class. An RV air conditioner usually needs a mid-size unit, so check its starting watts.

What is the lightest camping generator in your database?

The Westinghouse iGen2800 at 46.3 lb, just ahead of the Honda EU2200i at 46.5 lb.

Is a battery power station better than a generator for camping?

For small loads it is quieter and has no exhaust. For anything heavy it runs out fast: the EcoFlow Delta 2 runs a 1,000 W load for about an hour.

Can I run a camping generator on propane?

Only dual fuel models. In our database, propane output is lower than gasoline output on each of them.
