Review: Excellent Generator - 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: Well worth the investment - This unit is well worth the money. I’ve used it an entire season powering my 30’ camper trailer. It’s only got a 25amp plug, but will run a 30amp RV trailer with ease. Note, not to run water heater on electric and AC at same time. You will pop the generator breaker. But one without the other and it works absolutely fine. We just waited the 15-20mins it took for the water heater to satisfy then we’d turn on the AC. Definitely recommend. We’ve got we’ll over 300hrs on ours now and has never been a problem. We used this extensively from April-September as we cleared our property to build our house. You won't be disappointed. Starts first pull every time. Love this thing. ## Features - PowerRUSH Technology - Delivers over 50% additional starting capacity, allowing you to do more with less. - Up to 50% quieter, ideal for noise sensitive environments, up to 25% lighter, for better portability. - TRULY POWERFUL TECHNOLOGY - Clean power for delicate electronics. - Caravan Friendly - Connect directly to a caravan to power most caravan air conditioners up to 15,000 BTUs. - USB & Parallel Outlets - Connect 2 units together to double the power. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B079KRLHBT | | Additional Features | Portable | | Brand | Generac | | Brand Name | Generac | | Color | Orange-Coloured | | Customer Reviews | 4.5 out of 5 stars 343 Reviews | | Engine Displacement | 418 Cubic Centimeters | | Engine Type | 4 Stroke | | Frequency | 60 Hz | | Fuel Type | Gasoline | | Fuel type | Gasoline | | Ignition System Type | Electronic | | Included Components | Generac 7128 GP3500iO Portable Open frame Inverter Generator | | Is Electric | No | | Item Dimensions L x W x H | 50L x 41.9W x 41.7H centimeters | | Item Weight | 74.3 Pounds | | Item weight | 74.3 Pounds | | Manufacturer | Generac | | Manufacturer Part Number | 7128 | | Material Type | Steel and plastic | | Model Name | GP3500iO | | Model Number | 7128 | | Output Wattage | 3500 | | Power Source | gas-powered | | Power source | gas-powered | | Recommended Uses For Product | Camping | | Recommended uses for product | Camping | | Running Wattage | 3000 Watts | | Runtime | 11 hours | | Starting Wattage | 3500 Watts | | Tank Volume | 2.37 Gallons | | Total Power Outlets | 2 | | UPC | 696471072020 | | Voltage | 120 Volts | | Wattage | 3500 watts | ## Product Details - **Brand:** Generac - **Fuel type:** Gasoline - **Power source:** gas-powered - **Recommended uses for product:** Camping - **Wattage:** 3500 watts ## Images ![Generac GP3500iO Portable Electric Open Frame RV Friendly Inverter Generator, 3500 Starting Watts with PowerRush Technology - Image 1](https://m.media-amazon.com/images/I/61iPVBN+BbL.jpg) ![Generac GP3500iO Portable Electric Open Frame RV Friendly Inverter Generator, 3500 Starting Watts with PowerRush Technology - Image 2](https://m.media-amazon.com/images/I/51F9l3St67L.jpg) ![Generac GP3500iO Portable Electric Open Frame RV Friendly Inverter Generator, 3500 Starting Watts with PowerRush Technology - Image 3](https://m.media-amazon.com/images/I/61NXXkHtmvL.jpg) ![Generac GP3500iO Portable Electric Open Frame RV Friendly Inverter Generator, 3500 Starting Watts with PowerRush Technology - Image 4](https://m.media-amazon.com/images/I/61dJSRAdLCL.jpg) ![Generac GP3500iO Portable Electric Open Frame RV Friendly Inverter Generator, 3500 Starting Watts with PowerRush Technology - Image 5](https://m.media-amazon.com/images/I/61iqxf9EBCL.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent Generator *by J***M on 27 December 2022* I own a Honda EU2000 which cost $1200 and love it but I wanted a 3500 and didnt want to spend $2000+.
