Budget · $600 to $900

Best budget generators

Both picks run on gas or propane, have a 240V L14-30 outlet, and will handle essential circuits during an outage. You don't need to spend $1,000+ to get reliable backup power.

DuroMax XP5500EH

DuroMax · Dual Fuel · Open Frame

4,500W running 5,500W peak 240V L14-30 ✓

"The dual-fuel option is the reason I recommend this one. Stockpile a few propane tanks and you'll never deal with stale gas again. At $700, there's nothing better in this wattage range."

Premium · $900 to $1,400

If you're spending $1,000+ on a generator, it should last 15+ years and handle your essential circuits. These three deliver on that promise, and all three justify connecting them to your panel properly.

I've connected hundreds of portable generators to home panels across Greenville, Spartanburg, and Pickens County. I see which generators actually work in the field, and which ones cause problems. The picks on this page are what I'd tell a neighbor to buy, not a curated list of whatever pays the highest commission.
