Side by side
How we picked
This guide covers 9 generators from the pool, each with a title stating a first power figure from 5,001 to 9,000 watts (the seller's figure, often starting watts, never measured). The generators are compared on the details stated in each listing title: type, fuel, watts group, electric start, RV ready, and CO sensor. Picks are ranked first by the number of stated details (most first), then tri fuel before dual fuel before gasoline, then by the order in the pool file. Live prices are shown on the page but never ranked. No generator was started, run, or measured for this guide.
How to choose
Inverter, open frame or standby
The titles in this list name two kinds of machine: inverter and portable. An inverter generator is a different kind of machine from an open frame portable, and a standby unit is installed by a professional. The title states which kind a listing is, and that is the only evidence this guide uses. Choose the kind that matches where the generator will be used, and read the maker's page for anything the title leaves out.
Which fuels the title names
Each title names the fuel or fuels the generator accepts. Tri fuel means gasoline, propane, and natural gas. Dual fuel means two fuels, usually gasoline and propane. Gasoline means only gasoline. The EIA pages linked in the sources explain what each fuel is. If a fuel is not named in the title, this guide writes "not stated by the seller" and does not guess.
Starting watts and running watts in a title
The first power figure in a title is the seller's figure, and it is often the starting (peak) figure. The running figure is lower and is printed on the maker's page. This guide quotes each title's own figure and groups it as 5,001 to 9,000 watts. Never assume the first figure is the running figure; check the maker's page for the second figure.
Electric start, RV outlets and CO sensors as listing words
A title may state electric start, an RV-ready outlet, or a CO sensor. These are listing words, not measured results. If a title names an RV-ready outlet, check the outlet against the rig's own plug and the maker's page. If a title names a CO sensor, this guide quotes it only as "the title names a CO sensor." The maker's manual and the CPSC, CDC, and NFPA pages in the sources are where to read about them.
Who connects a generator to a house
Connecting a generator to a home is for a licensed electrician, the maker, and the local permit office. This guide never describes wiring steps. A standby unit is installed by a professional. Read the maker's manual before any connection.
What this guide leaves out (and why)
The catalogue holds no measured output, runtime, fuel use, tank size, noise level, weight, outlet list, engine size, emissions approval, transfer switch, warranty, or app data. This guide compares generators only through the details stated in each listing title: type, fuel, watts group, electric start, RV ready, and CO sensor. Anything not stated by the seller is written as "not stated by the seller," never guessed.
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, or placement. This guide compares generators only on the details stated in each listing title. For anything the title does not state, read the maker's manual and the CPSC, CDC, and NFPA pages linked in the sources. Those pages are where to read about carbon monoxide and generator use.
What does the first power figure in a title mean?
The first power figure is the seller's figure, and it is often the starting (peak) figure. The running figure is lower and is printed on the maker's page. This guide quotes each title's own figure and groups it as 5,001 to 9,000 watts. Check the maker's page for the running figure before choosing.
What is the difference between tri fuel and dual fuel?
Tri fuel means the title names gasoline, propane, and natural gas. Dual fuel means the title names two fuels, usually gasoline and propane. Gasoline means only gasoline. The EIA pages linked in the sources explain what each fuel is. If a fuel is not named in the title, this guide writes "not stated by the seller."
How are the picks ranked in this guide?
Picks are ranked first by the number of details the title states (type, fuel, watts group, electric start, RV ready, CO sensor; most first), then tri fuel before dual fuel before gasoline, then by the order in the pool file. Prices are shown on the page but never ranked.
