Features

  • DUAL-FUEL PORTABLE INVERTER GENERATOR: Runs on gasoline (3,000W / 3,800W peak) or liquid propane (2,700W / 3,400W peak), giving you fuel flexibility for home backup, camping, RV trips, and jobsites
  • CLEAN POWER WITH LESS THAN 3% THD: Inverter technology produces stable sine-wave output safe for laptops, tablets, CPAP machines, and other sensitive electronics without risk of damage from power fluctuations
  • ELECTRIC PUSH-BUTTON START WITH BACKUP RECOIL: Battery-included push-button ignition fires up the 212cc OHV engine reliably; 3,800W starting surge on gas handles RV air conditioner startup loads with headroom
  • UP TO 20-HOUR RUNTIME WITH ECONOMY MODE AND COSENSE SAFETY: Economy Mode extends gas runtime to 20 hrs at 25% load and reduces noise; dual COsense sensors automatically shut down the unit if CO reaches hazardous levels
  • 6 OUTLETS PLUS PARALLEL CAPABILITY FOR DOUBLED POWER: Four 20A GFCI outlets, one 120V/30A locking outlet, USB-A and USB-C ports, and parallel-ready design let you connect a second iQ3800 DF for up to 6,000W combined (kit #7668 sold separately)
  • 107-LB UNIT WITH NEVER-FLAT WHEELS AND FOLD-DOWN HANDLE: Integrated transport wheels and telescoping handle make repositioning manageable; EPA-compliant for 49 states with a built-in spark arrestor for campsite use
  • 3.28-GALLON TANK WITH LED FUEL AND OUTPUT DISPLAY: Intelligent LED panel shows real-time power output and gas fuel level at a glance; fuel selector and shutoff are both located on the control panel for fast switching
  • WHAT'S INCLUDED: Generator with 212cc OHV engine, engine oil, oil funnel, 12V lead acid battery, tool kit, 4 ft LP propane hose, and owner's manual; parallel kit #7668 sold separately

Description

The Generac iQ3800 DF (model 8944) is a 3,000-watt dual-fuel inverter generator that combines clean sine-wave power, multi-day runtime, and quiet enclosed operation into a portable package built for home backup, RV use, camping, and jobsites. How much power do I actually need? The iQ3800 DF delivers 3,000 running watts and 3,800 starting watts on gasoline — enough to simultaneously run a full-size refrigerator, a window AC unit, lights, and charge devices. On propane, running watts are 2,700W and starting watts are 3,400W. Is it safe for sensitive electronics? Yes — inverter technology keeps Total Harmonic Distortion below 3%, producing a clean sine wave that is safe for laptops, CPAP machines, tablets, and smart devices. How long will it run? On a 3.28-gallon gas tank at 25% load with Economy Mode on, runtime reaches up to 20 hours. At 50% load on a 20 lb propane tank, expect up to 16 hours — making extended outages or multi-day camping trips manageable on a single fill. Does Economy Mode reduce noise? Yes — Economy Mode adjusts engine RPM to match the load, lowering both fuel consumption and sound output. Turn it off when maximum starting surge capacity is needed. Is it RV ready? The unit includes a 120V/30A locking outlet (NEMA L5-30R). A TT-30R adapter is required for standard RV shore power connections. The 3,800W starting surge is sufficient to handle most RV rooftop air conditioner startup loads. Can I expand the power output? Yes — connect two iQ3800 DF units using Generac Parallel Kit 7668 (sold separately) for up to 6,000 combined running watts from a single outlet connection. Warranty: 3-year residential / 2-year commercial limited. Professional installation recommended for transfer switch applications.

  • Solid Generator
Style: 3,800 Starting Watts Pattern Name: 50 State
Very happy with the generator. The set up, namely adding the correct amount of oil, was trickier than expected, but the rest of the set up and use was easy. It starts easily. It runs quietly. It is a good value for what we paid for it. We primarily use it at a back up for when the power goes out (e.g., storms, etc.). We haven't had to use it under those conditions yet, but we've tested it and everything works as advertised. ... show more

  • Made with Obsolete Parts and Breaks Down Quickly
Style: 3,800 Starting Watts Pattern Name: 50 State
I cannot say enough bad about these generators. They break down and parts are not obtainable. Don't purchase one of these. Update: Finally got Generac to fix the problems through a service center. They have been drug through mud to get it repaired and they sent the wrong parts. Not reliable, very poor service and extreme repair times. Cannot emphasize enough, DONT BUY. UPDATE: The generator has been out for repair for 3 months and the repair parts are still not available. ... show more

Nothing better. I'm a general person. The battery they sold with the generator was defective and I left a message with Amazon and Not 1 person replied. 80 BUCKS LATER, NEW BATTER GENERATOR WORKS FINE.

  • Will not stay running
Style: 3,800 Starting Watts Pattern Name: 49 State
Worked for 6 hours and refuses to stay running. I’m an over the road trucker so I don’t have time to sit around trying to exchange an item, so I spent a little more money hoping for quality. This thing is a pile of junk. I couldn’t be less satisfied.

Great generator with plenty of power. The propane run is extremely quiet and virtually no smell. Wonderful little unit that has saves me many times already during power outages.

  • Compact, powerful generator but questionable reliability.
Style: 3,800 Starting Watts Pattern Name: 49 State
This generator seem well-made and compact. However the electric starter would not work and the instructions for connecting it do not correspond to what actually needs to be done. The picture in the manual does not show the actuall part of the connections that must be accessed. Had to use the manual pull starter but on the third pull the handle broke off and the rope disappeared into the recoil The mechanism was not accessible without removing several parts from the machine. We could not find a Generac service shop so had to use a local mechanic. It took him 3 hours of work to fix the device. I believe this generator has a basic design flaw. It seems to run well, a bit noisy and significant vibration, but I guess this is somewhat expected with a device such as this. I am reluctant to recommend this particular machine. ... show more
