28000 oh yea
Just used it for the first time on my 42 foot BBQ trailer. Ran everything all day with no problems.

Great buy
I bought this generator to try on our Drone business and didn’t know what to expect out of it. We have had it for 2 months and it works fabulous while powering our chargers and equipment on the job.
Dex56 –
Great Generator.
Bought the Duromax 11000 for my food truck and
Let me just say it did not disappoint, the remote start is my favorite accessory.
AllanShop –
Great inverter
We bought his inverter generator and have been very pleased so far with it
Darin45s –
The backup inverter I’ve always dreamed of
I bought this just a month ago and just recently did a test run on my home. I was able to power my house, literally, my whole house without worry. That is the kind of security with comfort my family deserves.

Duromax 28000iHT
Great machine. Surprisingly how quiet it is. You will need a 6-9 psi regulator for Natural Gas.
DW –
Best natural gas inverter generator in my opinion.
It’s heavy, but love the power. Wish they had pull out handles on both sides like the 16000 watts inverter
Alan T –
Best and most versatile generator on the market.
I purchased this generator to run my whole house and pool equipment. Having the two 50amp plugs was a must. This generator ran flawlessly on natural gas. Best investment I have recently made. Love it!
