Our take on the Genmax 5000W Dual Fuel Portable Generator

The Genmax 5000W is an open-frame dual-fuel inverter generator that runs on gasoline or propane and weighs under 60 lbs. It delivers 4,000 running watts on gas and 3,200 on propane, with 5,500 and 4,950 starting watts respectively, plus a 120/240V 14-50R outlet for transfer-switch or RV hookups. A CO shutdown sensor, auto idle and a digital data center separate it from bare-bones open-frame units, though it is louder and heavier than small inverter boxes. It suits RVers, tailgaters and homeowners who want backup power without a permanent standby unit.

Pros
  • Dual fuel runs on gasoline or propane
  • 120/240V 14-50R outlet supports transfer switches
  • CO sensor shuts the engine down on dangerous carbon monoxide
  • Under 60 lbs, light for a 5,000W-class unit
  • Inverter output is safe for electronics
  • Auto idle cuts fuel use and noise at light loads
Cons
  • 65 dB is loud next to closed-frame inverter generators
  • Only 2.11 gallons of gas means short runs at high load
  • Recoil start is listed alongside electric start, so confirm the battery setup
  • Open frame exposes the engine to weather and dust

What reviewers say

  • 4.6 / 5626 ratings

Owners rate it highly, praising the dual-fuel flexibility, the 240V outlet and the CO shutdown for the money. Complaints center on noise and on run time when pulling heavy loads.

What people mention
  • Dual fuelPraisedOwners like switching to propane for storage and long outages without draining the tank.
  • NoiseCriticisedReviewers say it is noticeably louder than closed-frame inverter units at high load.
  • RuntimeMixedThe 8-hour figure holds at half load, but heavy loads empty the small tank fast.
  • WeightPraisedAt under 60 lbs it is easy for one person to move and load.
  • CO sensorPraisedBuyers value the automatic shutdown as a safety backstop for garage and porch use.
  • StartingMixedElectric start works, but some owners report needing several recoil pulls in cold weather.

Questions and answers

Can it run a 30A RV air conditioner?
Yes. The TT-30R outlet and 4,000 running watts on gas handle a typical 13,500 BTU RV air conditioner plus lights and a fridge. On propane, running watts drop to 3,200, so start the AC before other loads.
Does it work with a home transfer switch?
Yes. The 14-50R outlet supplies 120/240V, which suits a manual transfer switch feeding a furnace, well pump or fridge circuit. It is not a whole-house generator, so manage loads.
How long does it run on a tank?
About 8 hours at 50% load on gasoline. At full load expect roughly half that, and propane runtime depends on the size of the tank you connect.
Is it safe to use near a house?
The CO sensor shuts the engine down when carbon monoxide builds up, but it is still a gas engine. Run it outdoors, away from windows and doors, never in a garage or basement.
What comes in the box?
The generator, a tool kit, a funnel and the owner's manual. A propane hose and regulator are typically included for connecting a tank; check the listing for the exact bundle.
Is it quiet enough for a campground?
At 65 dB it is louder than most campground quiet hours allow. Auto idle lowers the sound at light loads, but plan on a remote site or a closed-frame inverter for tent camping.
