Great Value

Delivered when promised. Truck had lift gate. Driver rolled it into my garage with pallet jack. Robust packaging and banded to a skid. Works as intended with no issues. Surprisingly quiet. I run this on natural gas only. On first attempt to start, It started on 3rd try. When you initiate starting, it will crank for about 5 seconds then stop. I guess this protects the starter. Subsequent starts it fires right up. There is no plastic cover or electrical connection cable included. The 12' gas line hose included is 1/2” diameter. This is the best value I could find for anything comparable.

Very happy

This thing is nice. I bought it because I have natural gas ram to the house. I'm very happy and only done the break in running my camper but have it to back the house up.

Everything I hoped for.

Generator was delivered on time and perfect condition and is everything I hoped for. The tri fuel is the only way to go.

this generator is sweet

I bought this unit after my Champion generator took a dump on me. Just wanted to say this unit has been nothing short of Amazing! It has the necessary outlets and not the typical over complicated amount, as well as extremely portable! Good Job Genmax!

Quiet and provides a lot of power! Great price!

Great generator used for over 200 hours, easy to use, overall quiet and provides a lot of power! Used on our food truck and at times ran for 72 hours straight with short breaks to refuel. Got it on a $750 samsclub discount great deal!

It's a Power Plant

Received on Feb11,2025. Was a little disappointed it came with no pallet because it traveled a long way. Upon opening the box they use sheets of wood to protect the top and bottom of the unit. The unit feels well built and came with a lot of accessories and features. It is big and heavy but is manageable with the handles. Everything is labeled on where everything is. Checked and double checked the unit thoroughly. Read the manual twice, added oil and it started on second attempt on Natural Gas, and will only be used to run on NG. This thing is really quiet and only have 15min runtime so I can not say on the longevity but hope it lasts for years with proper care and maintenance.

This is a neutral bonded generator by default

Only run for one hour break in so far but seems nice and is quiet. Only issue so far is when researching this before buying, the manual stated it was a floating neutral generator with an included bonding plug which is what I wanted for connection to my house as backup power. However, when it arrived it is a bonded neutral and there is no information on the Genmax FAQ page that the manual points you to on where the neutral to ground bond is that you need to remove. Genmax service also still thinks this model is neutral floating by default and I had to send them a picture of my front panel to show them that it said Neutral Bonded. They did not have any updated instructions for this model either.

Disappointed

This generator claims to have 6500 W running and 8500 W start but the generator I just replaced it with had 2900 running 3200 starting but was as powerful as this one. Also, the generator has shut itself off two nights in a row when I was sleeping.
