Best Portable Generators

As an Amazon Associate, Backyard Gear Pro earns from qualifying purchases.

The best generator for you depends entirely on what you need to power — a few essential circuits during an outage, sensitive electronics while camping, or a full job site. Below are the main categories worth comparing by use case.

We're linking to Amazon search results rather than specific listings, since exact models, prices, and availability change constantly — use these picks as a shortlist to compare current listings and specs yourself before buying.

How we picked: We grouped portable generators by power type (inverter vs. conventional) and output tier, weighing noise level, fuel efficiency, and reported reliability across manufacturer specs and category-wide buyer feedback.

Small Inverter Generator (Under 2,500 Watts)

Best for camping and powering electronics

  • Clean, stable power that's safe for laptops and phones
  • Quiet operation compared to conventional generators
  • Lightweight and easy to transport

Con: Not enough output for whole-home backup or high-draw appliances

Mid-Size Inverter Generator (2,500-4,000 Watts)

Best for partial home backup during outages

  • Enough power for a refrigerator, lights, and a few essential circuits
  • Still relatively quiet and fuel-efficient
  • Many models support parallel connection to double output

Con: Won't run central air conditioning or a well pump alongside other appliances

Conventional Generator (5,000-7,500 Watts)

Best for whole-home backup with a transfer switch

  • Enough output for most household circuits including a well pump or AC unit
  • More power per dollar than inverter models of similar output
  • Widely compatible with home transfer switch setups

Con: Louder and less fuel-efficient than inverter models

Dual-Fuel Portable Generator

Best for fuel flexibility during extended outages

  • Runs on gasoline or propane, useful if one fuel type is scarce
  • Propane stores longer than gasoline without stabilizer
  • Good option for households wanting backup fuel flexibility

Con: Slightly less efficient on propane than on gasoline

Portable Generator with Electric Start

Best for easy starting in cold or emergency conditions

  • No pull-cord struggle during a stressful outage situation
  • Especially useful in cold weather when engines are harder to start
  • Usually paired with a battery that can be charged while running

Con: Adds cost and a battery to maintain compared to pull-start-only models

Frequently Asked Questions

What size generator do I need for my house?
Add up the running watts of the appliances you want to power during an outage, then add the highest single starting-watt surge. For a deeper walkthrough, see our guide on what size generator you need.
Is an inverter generator worth the extra cost?
If you're powering electronics, camping, or want quieter operation, yes. For whole-home backup where raw output per dollar matters more than noise, a conventional generator is usually the better value.
Can I run a generator during rain?
Portable generators should be run in a dry, well-ventilated outdoor location, ideally under a purpose-built generator canopy — never directly exposed to rain and never indoors or in an attached garage.
Do I need a transfer switch?
Yes, if you want to safely power your home's wiring. Backfeeding through a wall outlet is dangerous and illegal in most areas — have a licensed electrician install a transfer switch.
