DuroMax XP13000HXT Generator vs Generac iQ3800 Dual Fuel Inverter Generator

These are different tools. The DuroMax XP13000HXT is a whole-home backup unit: 10,500 running watts on gasoline, 120/240V output, and tri-fuel so it can run on natural gas from a house line. The Generac iQ3800 is a portable inverter: 3,000 running watts, 120V only, quiet, and light enough for one person to move. Owners of the DuroMax praise the output and the CO shutdown; owners of the iQ3800 praise how quiet it runs and how easily it starts. Buy the DuroMax to back up a house; buy the iQ3800 to take power to a campsite or jobsite.

  • Choose the DuroMax XP13000HXT if you need to run a house during an outage, including a central AC or a well pump, and can connect it to natural gas or a large propane tank.
  • Choose the Generac iQ3800 if you need clean, quiet 120V power for a tailgate, campsite, jobsite or a few appliances, and you want to lift it into a truck alone.

Generac iQ3800 Dual Fuel Inverter Generator

  • 4.3 / 5396 ratings

Owners of Generac inverter generators generally praise the quiet inverter output and the dual-fuel flexibility, and the CO shutdown is seen as a real safety plus. Complaints tend to center on weight and on the lower output when running on propane.

What people mention
  • WeightCriticisedOwners say 107 lb makes it a two-person lift and awkward to move without wheels.
  • Dual fuelPraisedBuyers like having propane as a fallback when gasoline runs out or is hard to store.
  • Power qualityPraisedUnder 3% THD is cited as safe for laptops, TVs and other sensitive electronics.

Questions and answers

Which one can run my central air conditioner?
The DuroMax. Its 10,500 running watts and 240V output can carry a central AC. The Generac iQ3800 tops out at 3,000 watts on 120V, which is enough for a window unit or a small portable AC, not a whole-house system.
Which is quieter?
The Generac iQ3800. Its fully enclosed inverter case keeps it quiet enough for campgrounds and close neighbors. The DuroMax is an open-frame unit rated at 74 dB, which is loud.
Can I run either one on natural gas?
Only the DuroMax. It is tri-fuel and ships with a 15-foot natural gas hose. The Generac iQ3800 runs on gasoline or propane only.
Which lasts longer on a tank?
The Generac iQ3800. It runs about 13 hours on gasoline and 16 hours on a 20 lb propane tank at 50% load. The DuroMax runs about 8.5 hours on its 8.3-gallon tank at 50% load.
Is the Generac worth stepping up to over a cheaper open-frame inverter?
If quiet operation and clean power matter, yes. The iQ3800's under-3% THD and enclosed case are its main advantages, and owners consistently praise how quietly it runs and how easily it starts.
Can I move the DuroMax by myself?
Not easily. It weighs 246 lbs, so plan on two people or a ramp. The Generac iQ3800 weighs 107 lbs and has an integrated handle and never-flat wheels, so one person can move it.
