Our take on the Flex Power Super Quiet Portable Inverter Generator with CO Auto-Shutoff

The Flex Power Super Quiet Portable Inverter Generator is a dual-fuel (gasoline or propane) inverter unit rated at 5,500 watts peak, with electric and remote start and CO Auto-Shutoff that kills the engine when carbon monoxide builds up. It is aimed at RV, campsite, tailgate and home-backup use, and its inverter output keeps power clean enough for sensitive electronics. At 139 lb and 29.5 inches deep it is a heavy, bulky unit that suits a cart, truck bed or permanent install more than hand carrying. Its best new price is $849 at Flex Power as of November 5, 2026, with 4 stores listing it new.

Pros
  • Inverter output is clean enough for laptops, TVs and RV electronics
  • Dual fuel runs on propane when gasoline is scarce or you want to avoid stale fuel
  • CO Auto-Shutoff shuts the engine down if carbon monoxide rises
  • Electric and remote start save pulling a cord
  • Quiet operation is National Forest Service approved for campgrounds
Cons
  • 139 lb and 29.5 inches deep make it a two-person lift at best
  • Peak rating is 5,500 W with no separate running-watt figure given, so plan loads conservatively
  • Remote and smart start add electronics that can fail or need a battery kept charged
  • No wheel kit or handle is listed, so moving it means lifting or a cart

Questions and answers

Is $849 a good price for this generator?
It is the best new price found as of November 5, 2026, at Flex Power, with 4 stores listing it new. Compare against those other stores before buying, since inverter generators in this class often sell for $900 to $1,200.
How loud is it really?
Flex Power markets it as super quiet and National Forest Service approved for campground use. Owners back that up, though no decibel figure is published here, so expect normal conversation-level noise at close range rather than silence.
Can it run on propane only?
Yes. It is dual fuel, so it runs on propane or gasoline. Propane avoids stale fuel and carburetor problems, but it produces less power than gasoline, so check your load against the lower propane rating.
What can 5,500 watts run?
That is a peak figure. Expect to run an RV air conditioner plus lights and electronics, or a few home circuits such as a fridge, furnace fan and lights. Add up running watts, not just startup watts, before relying on it.
Does it come with a wheel kit?
No wheel kit or handle is listed. At 139 lb and 29.5 inches deep, plan on a cart, ramp or a fixed install rather than carrying it.
Is it safe to run near a house or tent?
The CO Auto-Shutoff shuts the engine down when carbon monoxide rises, which adds a layer of safety. It is still a fuel-burning generator: run it outdoors, away from windows, doors and tents.
