Side by side

How we picked

This guide's pool is 9 gasoline generator listings whose titles name gas or gasoline power and no second fuel. Each listing is compared on the details stated in its title: type, fuel, the first watt figure grouped into a range, electric start, RV ready and a CO sensor. Picks are ordered best first by the number of stated details, then by tri fuel before dual fuel before gasoline before not stated (all listings here are gasoline), then by the order in the pool file. The top pick states 5 details; the rest follow on 4 and then 3 stated details. Live prices appear with the listings, but no price comparison is made in the text.

How to choose

What the gasoline label means in these listings

Every listing in this pool has a title that names gasoline or gas power and no second fuel. That means the pick's fuel is read from the title alone; a title that names propane or natural gas is not part of this guide. The EIA gasoline page linked in the sources explains what gasoline is as an energy source.

Which type the title names: inverter, portable or standby

The titles in this pool name two kinds of machine: inverter generators and portable generators. Some titles say portable, some say inverter; a portable title and an inverter title describe different machine kinds. A standby unit is a third kind and is not in this pool; a standby unit is installed by a professional.

Starting watts and running watts in a title

Many generator titles print a first power figure and sometimes a second. In this pool, the Generac 8,125 prints 8,125 starting watts and 6,500 running watts, and the Generac 3,300 prints 3,300 and 2,500. The first figure a seller prints is often the starting (peak) figure, and the running figure is lower. The maker's page prints the running figure for models where the title leaves it out.

Electric start, RV outlets and CO sensors as listing words

Some titles name electric start, an RV-ready outlet or a CO sensor. These are listing words: the title names them, and this guide quotes them as stated. In this pool, 2 titles state electric start and 3 titles state an RV-ready outlet.

Who connects a generator to a house

Connecting a portable generator to a home's wiring is for a licensed electrician, the maker and the local permit office.

What this guide leaves out (and why)

This guide leaves out any detail the catalogue does not hold: runtime, fuel use, tank size, noise, weight, outlet lists, engine size, warranty terms and emissions approval beyond what a title states. The pool reads only the details stated in each listing title, so those figures belong on the maker's page.

Questions

Why does this guide only cover gasoline generators?

The pool for this guide is the set of listings whose title names gasoline or gas power and no second fuel. Titles that name propane, natural gas or more than one fuel are covered in the dual fuel and tri fuel guides on this site. The fuel detail is read from the title alone, so a listing without a second fuel is a gasoline listing here.

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, weight or outlet lists, and it does not say where a generator may run. The maker's manual and the CPSC, CDC and NFPA carbon monoxide pages in the sources are where those answers belong; this guide does not restate them.

What does the first watt figure in a title mean?

The first power figure in a title is the seller's figure, often the starting (peak) figure. The running figure is lower and is printed on the maker's page for each model. This guide groups that first figure into a range (for example 3,000 to 5,000 watts) and never adds a running figure the title does not print.

Which pick states an RV-ready outlet?

Three picks in this pool state an RV-ready outlet: the WEN 4500, the Champion 4000 and the Generac 3,300. For a travel trailer or motorhome, check the outlet against the rig's own plug and the maker's page before choosing.

Which titles state electric start?

Two titles state electric start: the Generac 8,125 and the GENMAX 6000W. The Champion 4000 title names recoil start instead, and the other titles do not state a starting method.
