Set name: 4400W Dual Fual InverterGenerator 2026


Features

  • Dual Fuel Power Gasoline & Propane (LPG) Delivers 4400W surge / 3600W rated watts (Gas) and 4000W surge / 3300W rated watts (LPG). Use gasoline for maximum output, or propane for cleaner combustion and longer engine life. For best performance, keep continuous load below 2800W (80% of rated power) and always connect the highest-wattage appliances first. The built-in overload protection will safely shut down the generator if total load exceeds limits, protecting your devices.
  • Extended Runtime with Real-World Usage Equipped with a 1.6-gallon fuel tank, this generator offers up to 11 hours of runtime at 25% load (lights, phone charging, small appliances) and 5.1 hours at 50% load (fridge, freezer, sump pump). Actual runtime varies based on load, fuel type, and altitude. For longer runtime, use economy mode and keep load below 1500W.
  • Quiet 76 dB Operation Residential-Friendly Operating at only 76 dB(A) from 23 feet, this generator is significantly quieter than traditional models. Perfect for use in neighborhoods, campgrounds, or RV parks you won't disturb your family or neighbors while keeping your essentials powered.
  • Reinforced Recoil Start & Durable Build Built with a heavy-duty pull cord and reinforced recoil spring mechanism, designed for repeated use. To ensure long-term reliability, pull the cord smoothly and fully extend it before recoil avoid jerky or snap-back pulls. Weighing 65 lbs with a compact footprint (19.3" x 16.9" x 16.5"), it's easy to transport and store.
  • Safety First CO Detection, Low-Oil Shutoff & Overload Protection Powered by an EPA-compliant 223cc OHV 4-stroke engine. Includes carbon monoxide (CO) detection that automatically shuts down the unit if dangerous levels build up, plus low-oil shutoff and overload protection.

  • Decent generator for the price
Set name: 4400W Dual Fual InverterGenerator 2026
No complaints so far. I completed the break-in process then used this for a several hour picnic event requiring power to multiple electric cooking devices and some other equipment. Worked very well & is relatively quiet even when under heavy load powering multiple items. The only time it has failed to start within 3 pulls was when I tried starting it with the engine switch in the off position or didn't have choke lever set properly. Nice generator for the price. ... show more

  • Don't!
Defective out of the box. Sounds like a bad governor. Runs 10 seconds. Overspeeds. Stalls.

  • As advertised and more!
This generator arrived 2 days after a massive storm power was out for 7 days.When it arrived it took about 30 minutes to assemble,set up,and run.First time using an inverter gen set and was surprised! Clean stable consistent power it ran for 7 days powering my essential circuits and the neighbors minus the air conditioners as the start and surge amps are not high enough unless you have a soft start kit on the compressor. Reduces the start/surge amps by 70 percent. It held steady at 6000 watts for days and averaged in eco mode 8 gallons of fuel every 16 hours. No oil consumption during its first 20 hours.The oil was easy to change took 5 minutes and after it did not use any either. I am no proffesional in regards to gen sets but this one is from my observations underrated as to what it can actually output and hold. I would definitely recommend buying this if you need a medium sized portable it did not let me or my neighbor down. ... show more

Set name: 4400W Dual Fual InverterGenerator 2026
I bought this for my aunt during the blackout, because she's on oxygen and has this huge oxygen machine that runs 24/7, it worked great. Plus a small freezer, refrigerator, and fans downstairs to keep the basement dry.

  • Loud
Set name: 4400W Dual Fual InverterGenerator 2026
Bought it for our RV and took it to a NASCAR race as they only do dry camping, no hook ups. According to the description it was supposed to be quiet. It was louder than any other generator there. I was embarrassed to even run it during the day
