Portable Generators for Backup, Job Sites, and Off-Grid Power

Portable generators give you dependable power wherever you need it: during an outage, on a job site, at the campsite, or off the grid. Krato Power carries portable generators from trusted brands like DuroMax and DuroStar, from compact recreational units up to 13,000-watt dual-fuel and tri-fuel workhorses and 16,000-watt inverter models that can back up an entire home. Every order ships free with no sales tax, a price-match guarantee, and free replacement parts for life.

Shop portable generators by fuel type

• Gasoline generators: easy-to-find fuel and strong starting power for backup and job sites.
• Propane generators: clean-burning fuel that stores for years, ideal for emergency preparedness.
• Natural gas and tri-fuel generators: run off your home's natural gas line for unlimited runtime, or switch between gas, propane, and natural gas.

Many DuroMax and DuroStar units are dual-fuel or tri-fuel, so you can run on whatever fuel you have on hand.

What size portable generator do you need?

Sizing comes down to the running and starting watts of what you want to power. A few essentials like a fridge, lights, and phone charging may need 3,000 to 5,000 watts, while running a well pump, furnace, and air conditioning together can call for 10,000 to 15,000 watts. Our 13,000W dual-fuel and tri-fuel units handle heavy loads and whole-home transfer switch setups. Not sure what you need?
