How we picked
This guide compares 15 portable generators from a pool of 16 listings whose titles say portable and not inverter or standby. The picks are ordered by the number of details each title states: type, fuel, watts group, electric start, RV ready and CO sensor. Most details come first; among equal counts, tri fuel ranks before dual fuel before gasoline, and then by the order in the pool. Each generator is compared on these stated details and on its live price. No generator is started, run, loaded, fueled, heard or measured; the catalogue holds no such data.
How to choose
Inverter, open frame or standby
Portable generators in this guide are open frame units whose titles say portable or open frame, and not inverter or standby. Inverter generators are a separate type, and standby units are installed by a professional. The title is the only source of type in this catalogue.
Which fuels the title names
The titles name gasoline, dual fuel (gasoline and propane), or tri fuel (gasoline, propane and natural gas). Propane alone or natural gas alone is not stated in this catalogue. The EIA fuel pages in the sources describe each fuel.
Starting watts and running watts in a title
The first power figure a title states is often the starting (peak) figure, and the running figure is lower. This guide groups picks by the first figure; it does not print a running figure. The maker's page states the running figure.
Electric start, RV outlets and CO sensors as listing words
A title may name electric start, an RV ready outlet (30A or 50A) and a carbon monoxide sensor or shutoff. When a title names them, they are listed; when it does not, this guide writes 'not stated by the seller'. RV ready means an outlet for a trailer or motorhome, but check the outlet against the vehicle's plug.
Who connects a generator to a house
Connecting a portable generator to a home is for a licensed electrician, the maker and the local permit office. This guide does not cover wiring.
What this guide leaves out (and why)
The catalogue holds no measured output, fuel use, tank size, noise level, weight, durability or warranty data. This guide compares only the details stated in each title and live prices. Read the maker's manual and the CPSC, CDC, EPA and NFPA pages for safe use.
Questions
What does this guide compare?
This guide compares 15 portable generators on the details each listing title states: type, fuel, watts group, electric start, RV ready and CO sensor, plus live prices. It does not compare noise, runtime, fuel use, or measured output.
Can this guide tell you how long a generator will run?
No. The catalogue has no runtime or fuel use data. The maker's page or manual states runtime and tank size.
What does the first watts figure in a title mean?
It is the seller's first figure, often the starting (peak) figure. The running figure is lower and printed on the maker's page. This guide uses the first figure for grouping.
How do you connect a portable generator to a house?
This guide does not cover wiring. A licensed electrician, the maker and the local permit office handle generator-to-home connections.
