The DuroStar DS13000MX is the best portable generator for most homes because its 10,500 running watts cover a central AC, refrigerator, well pump, and lights simultaneously — the core load during a multi-day outage.

For whole-home backup, running watts — not peak watts — determine what you can actually power hour after hour. The DS13000MX delivers 10,500 continuous watts on gasoline and 9,975 watts on propane, giving homeowners a fuel-switching option when gas stations run dry after a storm. Its 13,000 peak watts handle the startup surge of a 3-ton central AC compressor, which can demand 4,500–5,500 starting watts. Built-in CO Alert shuts the unit down automatically if carbon monoxide reaches dangerous levels.

  • DS13000MX running watts: 10,500W on gasoline, 9,975W on propane (approximately 5% lower).
  • DS13000MX peak (starting) watts: 13,000W — sufficient for central AC compressor startup surge of 4,500–5,500W.
  • DS13000MX runtime: 17 hours at 25% load (2,625W) on an 8.3-gallon tank.
  • DS13000MX noise output: open-frame design, typical of generators in this wattage class above 74 dB.
  • DuroStar residential warranty: 3 years covering defects in electrical and mechanical components.

How to Choose

  • Pick the DS13000MX if: you need to run central AC, a well pump, and a refrigerator simultaneously during a multi-day outage.
  • Pick the DS13000MX dual-fuel configuration if: you live in a hurricane corridor where gas stations sell out and you keep a propane tank on hand.
  • Pick the DS10000E if: your home load stays under 8,000W running and you want a lower price point without giving up OHV engine quality.
  • Pick the DS5000X if: you only need to run a refrigerator, lights, and a window AC unit — not central air — and portability matters more than whole-home coverage.
  • Pick an inverter generator instead if: you need to power laptops, CPAP machines, or other electronics directly — open-frame DuroStar models run above 5% THD, which is too high for sensitive devices.
