Portable Generators: Complete Guide

How it works

A portable generator runs on gasoline or propane, sits outside on wheels or a stand, and connects to select circuits via extension cords or a manual transfer switch. You start it yourself when the power goes out.

Cost range

$500–$3,000 for the unit; add $500–$1,500 for a manual transfer switch installation if you want it wired to specific circuits.

Pros & cons

Pros: much lower upfront cost, no permit required for basic extension-cord use, can be taken elsewhere (camping, job sites). Cons: manual start, limited to a handful of circuits, needs to be refueled manually during extended outages.

Is it right for you?

Best for homeowners on a budget who only need to power a few essential circuits (fridge, some lights, a sump pump) during occasional short outages.
