Best Generators Under $800: 3 Top Picks (2026)

Refreshed Oct 23, 2026

The WEN dual fuel inverter leads our picks for its high output, electric start, and built-in CO watchdog. All three generators in this guide are dual fuel and RV ready, and they all fall within the requested budget. We compared their stated specifications from the catalog and applied safety guidance from public agencies to help you decide. Prices shown are live from the store listing; we did not test these units.

3 picks from 4 generators that match this guide with a price we can quote today, made by 14 makers. Live prices throughout, each with the moment it was read.

The list in brief

Which pick fits you?

• For heavy power needs: If you need to power larger appliances or an entire RV, the WEN's higher wattage range and electric start make it the strongest pick in this group. See pick 1
• For remote start convenience: The Westinghouse offers remote electric start, so you can fire it up from inside a camper or tent without pulling a cord. See pick 2
• For a basic dual fuel generator: If you're happy with a pull start and want the essentials without extra features, the Champion delivers dual fuel and RV readiness at a simpler level. See pick 3

This generator tops the list because it offers the highest wattage range in the group, along with an electric start and a CO watchdog sensor. That makes it the most capable and convenient choice for running larger loads and for use as a backup power source.

Pros

• Highest wattage output of the three picks (5001 to 9000 W)
• Electric start for easy starting
• CO watchdog sensor adds safety
• Dual fuel runs on gasoline or propane

Cons

• Larger and heavier than the lower-wattage models
• May be more than you need for small loads

Good fit if

• Homeowners who want backup power for essentials during an outage
• RV owners who need extra reserve capacity

Skip if

• You only need to power a few small devices
• You want a lighter unit for frequent portability

Verdict: The best all-round choice for maximum output and convenience among these three picks.

This model brings remote electric start, so you can start it from a distance, which is handy in an RV or on a jobsite. It also includes a CO sensor, a feature the Champion does not list. It matches the Champion's output class but adds convenience.

Pros

• Remote electric start
• CO sensor included
• Dual fuel (gas and propane)
• RV ready

Cons

• Lower wattage than the WEN (3000 to 5000 W)
• May not be enough for simultaneous high-demand appliances

Good fit if

• RV owners who want to start the generator without leaving the camper
• Campers who want an added safety sensor

Skip if

• You need more than 5000 watts
• You prefer a simpler pull-start design

Verdict: A solid mid-range option that combines remote start and a CO sensor for a bit more convenience.

The Champion is the most straightforward pick here. It provides the same dual fuel and inverter benefits as the others but omits the electric start and CO sensor. For buyers who are comfortable with a manual start and will follow safety placement rules, it covers the essentials.

Pros

• Dual fuel (gasoline and propane)
• Inverter technology for clean power
• RV ready
• Simple design with fewer components

Cons

• No electric start listed by the seller
• No CO sensor listed by the seller
• Lower wattage than the WEN (3000 to 5000 W)

Good fit if

• Budget-conscious buyers who can start manually
• Users who will pair it with a separate CO alarm and place it outdoors

Skip if

• You want push-button start
• You want an integrated CO sensor

Verdict: A no-frills dual fuel generator that covers the basics if you add your own safety measures.

The specs, compared

Why these made the list

We started with a pool of three portable generators priced under $800 from the current store listings. All three are dual fuel, RV ready inverter models, which narrowed the selection to those with the most flexible fuel options and clean power output. Because the pool held exactly three qualified generators, we included all of them in this guide. Each price is read live from the listing at the time of writing; we did not physically test any unit. Our comparisons rely on the manufacturers' published specs and on safety guidance from federal agencies about generator placement and carbon monoxide.

Things to weigh before buying

Power output

To size your generator, add up the wattage of the appliances you plan to run. The WEN covers a larger range, while the other two are similar. Remember that starting watts matter for motors and compressors.

Fuel type

Dual fuel lets you switch between gasoline and propane, which is useful for storage or during fuel shortages. Propane has a longer shelf life, but gasoline is often easier to find during a storm. Consider what you store and how often you refill.

Inverter vs. conventional

Inverter generators produce cleaner electricity, which is safer for sensitive electronics like laptops and phones. All three picks are inverters, so you get that benefit regardless of choice.

Safety features

Carbon monoxide is a serious hazard. The CPSC and CDC recommend running generators outdoors at least 20 feet from windows, doors, and vents. A CO sensor can shut the unit off if dangerous levels are detected. The WEN and Westinghouse list this feature; the Champion does not.

Starting method

Electric start is more convenient, especially in cold weather. Remote start adds even more flexibility. Pull start is simpler but requires more effort. Decide what fits your usage pattern.

Questions

Can I use a generator inside my garage?

No. Carbon monoxide is colorless and odorless and can kill quickly. The CPSC and CDC state that generators must be operated outdoors only, at least 20 feet from any opening. Never run one indoors, even with doors open.

How far should a generator be from the house?

At least 20 feet away from windows, doors, and vents, with the exhaust pointing away. That distance reduces the risk of CO entering the home. Also ensure you have a battery-operated CO alarm inside.

What does dual fuel mean?

It means the generator can run on either gasoline or propane. That gives you flexibility in fuel choice and storage, as propane can be stored for longer periods without going bad.

Which one is best for an RV?

All three are RV ready, but the Westinghouse adds remote start, which is convenient from inside the camper. The WEN offers the most power if you have high-demand appliances.

Do I need a generator with a CO sensor?

It's a valuable safety feature that can automatically shut off the engine if CO levels rise. The WEN and Westinghouse include one. If you choose the Champion, consider adding a CO alarm inside your living space.
