Portable Generators

When the power goes out — or the job site has none — a portable generator is the fastest answer. This collection stocks Generac's portable lineup, the brand that defines the category: from the GB2000 power station for silent, indoor-safe device charging, up through the PM series workhorses at 4,500, 7,500, and 9,400 watts for homes, job sites, RVs, and events.

Current models cover the real-world range. The PM4500 and PM7500 come in dual-fuel versions that run on gasoline or propane — critical flexibility when gas stations lose power too — with CO-sense automatic shutdown that protects against carbon monoxide buildup. The PM9400E adds electric start and enough output to run a home's essentials through a manual transfer switch: refrigerator, furnace blower, sump pump, lights, and outlets. Every model here is 49-state or 50-state/CSA compliant as listed.

Sizing rule of thumb: add the running watts of everything you want to power, then add the largest motor's starting surge — refrigerators and pumps triple their draw for a second. Our team sizes portable generators daily; tell us what you need to run and we will match the unit, the inlet box, and the cord set. Pair any portable here with a Generac power inlet box and manual transfer switch from our transfer switch accessories collection for a safe, code-compliant home hookup.

What Is a Portable Generator?

A portable electric generator for home is a movable power source that converts fuel into electricity. Unlike permanently installed standby units, portable models can be easily relocated, stored when not in use, and deployed quickly when power is needed.

They come in various sizes, fuel types, and output capacities — making them suitable for both small devices and entire households.

Why Every Home Needs a Portable Generator

Power outages are unpredictable and can cause major disruptions. A portable generator for house backup provides:

• Peace of Mind – Never worry about spoiled food, dead batteries, or medical equipment failure.
  
• Versatility – Power tools, electronics, and outdoor gear anywhere.
  
• Emergency Preparedness – Stay safe during storms, wildfires, or grid failures.
  
• Affordability – Portable models cost less than whole-home standby systems.
  
• Mobility – Use one unit for home, worksite, or recreation.
