Review: I own a Honda EU2000 which cost $1200 and love it but I wanted a 3500 and didnt want to spend $2000+. So I bought a Generac 3500iO last year, used it on my farm that does not have electric and it worked great. Strong generator. I put it in storage for a year in 2021, then came back to my farm in 2022. Filled it with fuel, and it started easily on the 2nd pull. I put about 10 hours on it this year and still works perfect and starts very easy. Love it just as much as my Honda so far. And its very quiet, super pleased with this product. Its easy to carry with the medal frame. Love it. I like the open frame so that the engine gets plenty of air and runs cool. Perfect balance and design and function. So I just ordered a 2nd so I can run parallel for more power when needed. Highly Recommended. 2 generators for twice the power and half the price. This is the only brand I could take a chance on other then Honda. Generac did a great job with this model.
Review: It is small enough to fit in my truck bed with the tonneau cover on and light weight enough (74 lbs) to manage. It provides as many watts (3,500) as much heavier generators, is relatively quiet, and it started with the first pull of the cord. It has a 30 amp input, which is perfect to use it to power my travel trailer, but it does require an adaptor to connect them.

## Questions & Answers

**Q: Generac 30 A for RV?**
A: I have a Coleman Mach 8 RV AC - 13,500 BTU. This generator alone will not start the AC Compressor. It can run everything else in my AC including the fan, but not the cooling of the AC. My solution is to install a softstart to the AC, there are YouTube videos showing this generator able to start a 13,500 BTU AC when it has a softstart on it.

**Q: Where is it made?**
A: Made in China and is the same generator as the Pramac iq3500 in Europe. It is an excellent quality generator with very quiet operation.  A little heavy so a dolly or wheel kit is mandatory.  Im not sure why they decided to forgo the wheels as standard equipment. This has the same internals as the H.F. 3500 Predator down to the Hemi head 212cc engine made by loncin.

**Q: What is the dB rating on this unit?**
A: <1 dB at 3 miles and >50 dB at 1/2”.  That is what the manufacturer is saying.  Without a standard it is worthless information.  I can claim mine is 47 dB but that measurement is at 30’ from the quietest side another claims 57dB but that is at 10’ Reporting the max reading from any side.  Guess which one is quieter?  Every generator is 0dB if you stand far enough away.

**Q: Can you parallel this with a 2200 series?**
A: A Generac GP3500iO cannot be paralleled with a GP2200i and should only be paralleled with another GP3500iO.

### ⭐⭐⭐⭐⭐ Review
*by M***E on 20 February 2024*

These are great little generators. I work with a non-profit that does disaster response and the other small generators that we have used for years are no longer being manufactured. When we started looking for replacements, I wanted something with a good brand name behind it, small and compact, powerful, and easy to transport and maintain. These are usually used when there are disasters and people need them to provide temporary power for their homes. I ordered one of these to test it and then ordered nine more once I determined this was what we wanted. These are compact and have the frame all the way around them for ease in carrying and for protection. They are super easy to start and run smoothly and efficiently. One great thing about these is that they come with everything you need to get started (sans gas) in that there is a funnel and a bottle of oil that contains the exact amount you need. I wish there was somewhere to store the funnel and tools that come with it, but I'll likely tie a mesh or other bag to them. I'm very pleased so far and will use these for our next disaster. One tiny little thing that could improve these is if they would include holes for your hands in the box so they would be easier to grasp and move. That's a very small thing but when you are moving lots of these just a little handhold on each side would be so helpful.
