This portable 4,000W gas inverter generator delivers clean power with under 3% THD and runs up to 14 hours at 25% load. It has a 30A outlet for heavier loads, and its portable roll-frame design makes it easy to move for camping, RV trips and home backup power.

A gas generator makes its own power from fuel, so it can run for as long as you keep it fueled, with no wall outlet needed. Always run it outdoors and well away from windows, doors and vents.

Good to know

Add up the wattage of everything you plan to power at the same time and keep it below the generator's output rating. Motors and compressors briefly draw more power when they start. A portable generator is not designed to run an entire home.

Who this is not for

Anyone who needs to power an entire home, central air conditioning or other heavy loads at once, or who needs to run power indoors or in an enclosed space.

Safety and care

  • Run it outdoors only, at least 20 feet from the house, with the exhaust pointed away from windows and doors
  • Never run a generator in a garage, shed or any enclosed space, even with the door open
  • Let the engine cool before refueling, and store fuel in an approved container away from heat
  • Check the oil level before each use and follow the manual for maintenance

Frequently asked questions

What can it run?
Add up the running watts of the items you want to power at the same time and keep the total below the generator's 4,000W rating.

Can I use it indoors?
No. Gas generators produce carbon monoxide and must only be used outdoors in open air.

What does under 3% THD mean?
THD measures how clean the power is. Lower is better, and under 3% is good for sensitive electronics such as phones and laptops.

Can I bring it on a plane?
No. Gas generators cannot be transported by air.
