Side by side
How we picked
The pool holds 13 generators whose listing titles state a first power figure from 3,000 to 5,000 watts, per the group rule. Each pick is compared on the details the title states: type, fuel, watts group, electric start, RV ready and a CO sensor. Picks are ranked first by the number of stated details, then dual fuel before gasoline before fuel not stated, then by the order in the pool file. The title's first watt figure is quoted as stated and may be the starting figure; the running figure is not in the catalogue. Live prices are shown on the page, but no price appears in this text.
How to choose
What the title's watt figure means
The first figure a listing title states is often the starting (peak) figure, not the running figure. The running figure is lower and is printed on the maker's page. This guide quotes only what the title states and says it may be the starting figure.
Inverter or open frame
Titles name either inverter or portable. Inverter generators are a different kind of machine from open frame portables, and the title states which kind. The catalogue does not measure sound levels or output quality.
Which fuels are named
Some titles name gasoline only, others name dual fuel (gas and propane). If a title names no fuel, this guide says not stated by the seller. The EIA pages in the sources explain what each fuel is.
RV outlets and CO sensors as listing words
A title may state an RV ready outlet or a 30 amp outlet. A title may name a CO sensor. These are listing words, not safety promises. Read the maker's manual and the CPSC, CDC and EPA pages linked in the sources.
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 does not cover wiring, transfer switches or backfeeding.
What this guide leaves out
The catalogue has no measured output, runtime, fuel use, tank size, noise level, weight, outlet list, engine size or warranty data. This guide compares only the details stated in each title and live prices.
Questions
Does this guide cover noise or runtime?
No. The catalogue has no measured noise, runtime or fuel use data. The maker's manual and the CPSC, CDC and NFPA pages linked in the sources are where to read about them.
What does the watt figure in the title mean?
The title's first figure is often the starting (peak) figure. The running figure is lower and printed on the maker's page. This guide quotes the title's figure as stated and does not compare running watts.
Which fuels are covered?
This guide covers gasoline and dual fuel titles as stated. Propane alone or natural gas alone are not stated in these titles.
Why is one generator ranked above another?
Picks are ranked by the number of stated details, then dual fuel before gasoline before fuel not stated, then by the order in the pool file. Prices are shown on the page.
