The picks at a glance
Which one should you buy?
- For a home on a propane tank: A dual fuel portable generator that names gasoline and propane in its title gives you a second fuel option when gasoline is hard to find. Check the watts figure against what you plan to power. See pick 1
- For weekend camping trips: A portable generator with an RV ready outlet in its title can connect to a camper's plug, but check the outlet against your rig's own plug and the maker's page. See pick 7
- For a job site or a workshop: A portable generator with electric start in its title saves you from pulling a cord. The watts figure tells you the seller's first number, which is often the starting figure. See pick 5
- For a travel trailer or motorhome: Look for a title that names an RV ready outlet and a CO sensor. The RV ready outlet is a stated detail; the CO sensor is a stated feature, not a promise of safety. See pick 6

How we picked
This guide covers 8 portable generators whose titles say dual fuel. The pool was filtered to open frame portables (not inverters) that name gasoline and propane. Each pick is compared on the details its listing title states: type, fuel, the first watts figure, electric start, RV ready, and CO sensor. The ordering rule ranks picks by the number of stated details (most first), then tri fuel before dual fuel before gasoline before not stated, then by the order in the pool file. The top pick states 3 details; the next picks state 2 or 1. Live prices are printed on the page and are not part of the ranking.
How to choose
Inverter, open frame or standby
The title tells you which kind of machine you are looking at. A title that says portable and does not say inverter is an open frame portable generator. A title that says inverter is a different kind of machine. A title that says standby, whole home, or home generator and does not say portable is a standby unit, which is installed by a professional. This guide covers only portable generators whose titles say dual fuel.
Which fuels the title names
A dual fuel title names two fuels, usually gasoline and propane. The EIA pages in the sources explain what gasoline and propane are as fuels. The title does not say how the generator switches between fuels or how to store either fuel. If a title names only one fuel, it is not dual fuel. If a title names three fuels, it is tri fuel, which is outside this guide.
Starting watts and running watts in a title
The first watts figure in a title is often the starting (peak) figure, not the running figure. The title usually does not say which figure it is. The running figure is lower and is printed on the maker's page. This guide quotes each title's own figure and groups it into a range, but does not give a running figure the title does not print.
Electric start, RV outlets and CO sensors as listing words
A title that says electric start means the seller states that feature. A title that says RV ready or names a 30 amp or 50 amp RV outlet means the seller states that outlet. A title that names a CO sensor means the seller states that feature. If a title does not say one of these, the detail is not stated by the seller. The RV guide says to check the outlet against your rig's own plug and the maker's page.
Who connects a generator to a house
Connecting a portable generator to a home's electrical system is for a licensed electrician, the maker, and the local permit office. This guide does not describe how to connect a generator to a house. A title that says transfer switch ready is a stated detail, not a wiring instruction.
What this guide leaves out (and why)
The catalogue has no data on noise, runtime, fuel use, tank size, weight, outlet types or counts, engine size, alternator type, harmonic distortion, parallel kits, app quality, durability, build quality, reliability, warranty terms, emissions approval, sales, or popularity. This guide compares generators only through listed details: type, fuel, watts group, electric start, RV ready, and CO sensor. The maker's manual and the CPSC, CDC, and NFPA pages in the sources are where to read about those topics.
