Side by side
How we picked
This guide draws from a pool of 20 dual fuel generator listings. The group rule used is: listings whose title says dual fuel, or names both gasoline and propane, or both propane and natural gas. All 20 listings state dual fuel. Each pick is compared only on the details stated in its listing title: type, fuel, the first watts figure grouped as under 3,000 W, 3,000 to 5,000 W, 5,001 to 9,000 W and over 9,000 W, electric start, RV ready and a CO sensor. The order is: most stated details first, then tri fuel before dual fuel before gasoline before not stated, then pool order. Since every listing here is dual fuel, the fuel tiebreaker does not change the ranking. Live prices are printed on the page beside each pick and are not part of the order.
How to choose
Inverter, open frame or standby
The title names which kind of machine it is: inverter, portable (often open frame) or standby. A standby unit is installed by a professional and connected to the home, while inverter and open frame portables are moved to where you use them. Read the title's own word for the type, never guess it from a picture.
Which fuels the title names
Dual fuel in a title means the listing names two fuels, usually gasoline and propane. This guide covers only dual fuel listings, and each pick's fuel is quoted as stated. The EIA gasoline and hydrocarbon gas liquids pages in sources explain what gasoline and propane are.
Starting watts and running watts in a title
The first watt figure a title prints is often the starting (peak) figure. The running figure is lower and appears on the maker's page, usually as the second figure. This guide groups the first figure only and never states a running figure the title does not print.
Electric start, RV outlets and CO sensors as listing words
Electric start, RV ready and a CO sensor are details a listing may name. RV ready points to an outlet that should be checked against the rig's own plug and the maker's page. A CO sensor is named where the title says so, and the maker's manual explains what it does.
Who connects a generator to a house
A standby unit and any home connection are for a licensed electrician, the maker and the local permit office. This guide does not give wiring, transfer switch or fuel handling instructions. The manual and the authorities in sources cover the rest.
What this guide leaves out (and why)
The catalogue holds no measured output, runtime, fuel use, tank size, noise or weight, so this guide never claims any of them. Compare on the details a title states, and read the maker's page for the details this guide cannot cover.
Questions
Does this guide cover noise, runtime, fuel use or where to run a generator?
No. The catalogue has no data for noise, runtime, fuel use, tank size or installation, and this guide never states any of them. Where to run a generator is not covered here. Read the maker's manual and the CPSC and CDC pages linked in sources for carbon monoxide safety and placement information.
What does dual fuel mean in the title?
A title that says dual fuel names two fuels, usually gasoline and propane. This guide covers only listings whose titles say dual fuel or name both gasoline and propane. The pool rule used for this guide is the group rule: listings whose title says dual fuel, or names gasoline and propane, or propane and natural gas.
What is the first watt figure in a title?
The first figure is often the starting (peak) figure. The running figure is lower and printed on the maker's page, usually as the second figure. This guide groups the first figure only and quotes it as the title states it.
Which pick has the most stated details?
The WEN 6800-Watt Dual Fuel RV-Ready Electric Start Portable Inverter Generator states the most details: type, fuel, watts group, RV ready, a CO sensor and electric start. That is six of the six details this guide tracks, and it is the first pick in the list.
Why is the WEN 6800-Watt first on the list?
It ranks first because its title states six details, more than any other listing in the pool. The ordering rule is: most stated details first, then tri fuel before dual fuel before gasoline, then pool order. Since all listings here are dual fuel, fuel order does not change the ranking.
Does the guide recommend a generator for a specific appliance?
No. No listing is tied to a specific appliance or load in this guide. The first watt figure is quoted as the title states it, and the guide never promises that a generator runs a given device. Compare the stated details against your own needs.
