Small generator big power!

Genmax generator company is staying ahead of the game with this unit! I needed a unit in a small form factor design that would pack a punch for my 2 acre lot where power was a needed. After doing some homework I settled on this generator. You can’t beat the value and quality of this machine, especially since it can output 28 amps!! It pushed my Jack hammer rated at 15 amps with ease. Super quiet too. The best part is that they have live customer service agents answering their phones out in California! Good job Genmax!

A Lifesaver During Power Outage!

I recently had the opportunity to use Genmax generator during an unexpected power outage, and I couldn’t be more impressed! The generator started effortlessly and provided steady power throughout the duration of the outage. We primarily used it to keep our refrigerator running, and it performed flawlessly—ensuring none of our food spoiled. The fuel efficiency was outstanding; a single tank lasted much longer than I anticipated. It’s relatively quiet for its size, and setup was a breeze even for someone like me, who’s not very mechanically inclined. It conveniently came with the oil and all the parts and accessories needed. What stood out the most was how dependable it felt in a stressful situation. The peace of mind it gave us was invaluable. I highly recommend this generator to anyone looking for a reliable backup power solution for their home. It’s a solid investment in preparedness and comfort during emergencies!

Well built generator!

Generator was packaged well. Delivery was quick, received in 2 days. I purchased generator for travel trailer but I recently needed to weld landing gear on my work trailer and my breaker at home was popping. I hooked up welder and grinder to my new Genmax and I was able to weld and fix landing gear on trailer. Was not sure if generator was going to be able to handle welder. Genmax did a great job with this product and for the price you cannot beat it.

Genmax Your Winning! Extremely Satisfied Customer

Amazing Unit. Just what I needed. A compact generator that packed a mighty punch. I love the fact that I can use both propane or gas. I will mostly use this generator using propane while camping with my family. The unit comes equipped with a 30A outlet, perfect for my 20ft travel trailer. To perform a quick test of the unit, I used my air compressor. In full disclosure, I am not the most technical person, so I did have to call tech support and actually spoke with a live person from the United States! The tech support guy's name was Oscar and he let me know that I had all of the settings correct, except I forgot to turn the propane tank in the open position. Oh Boy.. It's always the little things that I forget to do. Anyway, the unit fired right up on first pull. I let the unit run a little, maybe 2 minutes, before I plugged in my compressor. The compressor fired right up the second I flipped the switch. I could not be happier. This unit gives me all of the functionality that I need at an amazing price point. Genmax your Winning!

So easy for a first time user

We purchased this for a small side business for washing cars. So impressed with the power you get from such a small machine, and really quiet. We used our pressure washer and small vacuum, and it worked great! We’re not familiar with generators but this was so easy to set up and get started right out of the box. Added the oil it came with and connected to our propane tank and was up and running in a few minutes! This thing is so great!

Pretty quiet, very lightweight

Solid Generator, very compact and lightweight... i was a bit skepitcal on the price considering the comp units are around 700 but the bang for buck on this is hard to beat. its my go to camper unit, lightweight and not too loud, its not the quietest out there but its definietly not loud or noticibly quiet. pretty solid and great buy. i keep my onboard gen off and utilize this throughout the night and it runs 8-10 hours easy for me.

Generator- Solid unit but not the quietest

I purchased this generator to use with my 34' RV. I currently have a Harbor Freight Predator 3500 gasoline only. Regardless if I ran on gasoline or propane, it was 10dB louder than the Predator when running the AC on the RV. On the plus side, it is compact and can be moved with one person.

Wears out very fast

Aluminum wear dust in oil at every oil change even when changing every 30 hours of use. On off knob became VERY difficult to turn after just a few uses.
