Fuel logistics
Stored fuel is the real backup plan.
Propane keeps indefinitely; gasoline needs rotation. Compare fuel strategies and storage practice before the first outage tests them.

Our research approach
Documented watts, admitted limits.
Our comparisons use listing-documented specifications and public review data. They are not hands-on product tests.
We explain which loads a generator class may suit and what still needs checking. Confirm current details with the manufacturer and seller, and keep installation questions with a licensed electrician.
