Description
Zoom on the Generac GP3500iO
In a nutshell, the Generac GP3500iO is a compact and lightweight portable inverter generator mostly geared towards:
- RV travellers looking for even more independence
- People occasionally participating in outdoor fairs, festivals or events
- DIYers who wish to improve their efficiency with tools
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
- Tailgating and campground aficionados with the desire of enjoying power anywhere they go
In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.
Power & Run Time
The Generac GP3500iO's design includes a gasoline-fueled 212 cc Generac OHV 4-stroke engine. With a 120V output, it gives a running wattage of 3,000W and also a peak wattage of 3,500W. In addition, the device is parallel capable (GP3500iO Parallel Kit not included) and thus, can be linked to a similar or compatible unit for added power.
The inverter generator features a conventional pull-start mechanism. It features Generac's PowerDial™, an easy-to-use dial with three operation settings.
The GP3500iO can operate for up to 11 hours with a full tank (fuel consumption around 0.22 GPH), due to its fuel capacity of 2.37 gallons.
The GP3500iO produces a clean sine wave: thanks to a <3% Total Harmonic Distortion (THD), your sensitive electronics can be safely plugged in the AC outlets.
Outlets
The control panel provides the upcoming 3 AC outlets:
Additionally, it features 2 DC outlets: there's two 5V USB ports with which you may charge electronics, for example mobile phones or tablets, conveniently.
This Generac generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor. However, it is still not quite RV ready.
Portability
With its dimensions of L19.3 x W16.9 x H16.4 in, the conventional, open frame design of the Generac GP3500iO offers stability and allows the generator to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.
As the GP3500iO's weight is only 74.3 lbs, it can follow you and your power needs anywhere. Additionally, the generator’s mobility is also improved by its open frame design, as it can be easily grabbed and shifted.
Features
One of the many GP3500iO's features is the data center, included in its control panel, which conveniently provides information on the lifetime run hours and thus, helps you monitor its activity and status.
In addition to this info, several light indicators serve to show you when the generator is on overload, the oil level is too low and the generator is ready.
As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.
Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Generac GP3500iO also comes with some accessories: oil, funnel and tool kit are included.
Emissions
The Generac GP3500iO is CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.
Moreover, it features a spark arrestor and therefore, can be used in forested areas.

The Generac GP3500iO versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Generac GP3500iO compare to inverter generators of similar power (between 2500 and 3500 W).
- As for its weight, the Generac GP3500iO weighs only 74.3 pounds, making it one of the lighter inverter generators in the 2500-3500 rated wattage category. If weight is your top priority, one of the champions in this power category is the Pulsar PGD40iSCO, weighing just 46 pounds.
- As far as autonomy is concerned, providing up to 11 hours of runtime with a full tank at a 25% load, the GP3500iO falls into the low end in comparison with other inverters of a comparable power output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Champion 200914, reaching up to 22 hours.
- Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This inverter generator is not fuel efficient compared to devices of similar output: its estimated fuel consumption stands at 0.22 GPH at a 25% load. If you wish to acquire one of the most gasoline efficient products of this power range, the Energizer eZV3500P, with a fuel consumption of 0.13 GPH could be in your good books.
Here's a list of the most popular specific comparisons:
Price comparison
As you can see from this interactive chart, when compared to other 2500-3500W inverter generators, the Generac GP3500iO is on the cheap side of the price range.
It can therefore be a really good buy if you're looking to acquire a budget generator.

What is the noise rating of the GP3500iO?
Due to the lack of standardization in noise emission measurement, Generac does not provide their units' noise levels.
Does it have an eco mode? (Asked March 19th, 2020)
There is an economy switch that can be put to "ON" when running appliances or equipment that are resistive loads (non-motor starting), such as TVs, lights, laptops, etc.
I want a fuel shut off valve where do I find it (Asked September 24, 2020)
The "OFF" position of the PowerDial Switch stops the engine and shuts off fuel flow.
This unit is a inverter generator ,why do you say it isn't for RV . Is it good for Small 24 ft. Travel trailer? 1 small roof air conditioner? And tv outlets few other things ? (Asked March 20, 2021)
We did not say it's not for RV. We said it's not RV-Ready, since it does not have a TT-30R outlet. This does not mean that the unit is not suitable for an RV. You may read our definition of RV-Ready and use our wattage calculator to estimate your appliances power needs.
