Zoom on the Generac iQ3500

In a nutshell, the Generac iQ3500 is a compact portable inverter generator mostly geared towards:

  • RV travellers looking for even more independence
  • People occasionally participating in outdoor fairs, festivals or events
  • Amateur DIY lovers
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Camping and tailgating hobbyists looking for a portable power source

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Generac iQ3500 in use

The Generac iQ3500

The Generac iQ3500's design includes a gasoline-fueled 212 cc Generac OHV 4-stroke engine. With a 120V output, it gives a running wattage of 3000W and also a peak wattage of 3500W. Additionally, as the generator is parallel capable (Generac 7668 Parallel kit (opens in a new tab) not included), it can be linked to a second unit for more power.

This inverter generator can be started via a conventional pull-start mechanism, or a convenient and easy-to-use electric starter (battery included). It features Generac's PowerDial™, an easy-to-use dial with three operation settings.

The iQ3500 can operate for up to 14.1 hours with a full tank (fuel consumption around 0.18 GPH), due to its fuel capacity of 2.6 gallons.

As the iQ3500 produces a clean sine wave, with a <3% Total Harmonic Disruption (THD), sensitive electronics may be plugged in the AC outlets safely.

Outlets

The control panel includes the following 3 AC outlets:

Duplex 120V 20A (5-20R)
120V 30A (L5-30R) receptacle

It also sports 2 DC outlets: there's two 5V USB ports allowing you to conveniently charge electronics such as mobile phones and tablets.

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

The Generac iQ3500's characteristic encased inverter generator design (L23.7 x W18 x H21.7 in), provides an esthetical advantage over any ordinary, open frame product. The featured design follows the latest trends and is ideal for easy and recreational use.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 109.1 pounds. Thus, you may also want to consider purchasing a wheel kit for this generator, similar to this one (opens in a new tab).

Features

Panel of the Generac iQ3500

The iQ3500's control panel

To help you monitor the iQ3500's status and activity, its control panel is equipped with a digital data center, giving you information on the power output, lifetime run hours, remaining run time and fuel level.

In addition to this info, the light indicators show you if the generator is ready, the generator is overloaded and the oil level is too low.

As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you use it with a peace of mind.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Generac iQ3500 also comes with several accessories, including: funnel, tool kit and oil.

Emissions

The Generac iQ3500 is CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

Moreover, it features a spark arrestor and therefore, can be used in forested areas.

Product Videos

The Generac iQ3500 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Generac iQ3500 compare to generators of similar power (between 2500 and 3500 W).

  • Having a dry weight of 109.1 lbs, the Generac iQ3500 belongs in the expected weight range for generators which produce 2500 to 3500 rated watts. In terms of weight, one of the champions in their power range is the Generac GP3300i, standing at just 59.5 lbs.
  • The iQ3500, falls within the average autonomy range compared to generators of a roughly same power, with a run time of up to 14.1 hours at a 25% load and a full tank. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Champion 200914, boasting with 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 reaches an estimated fuel consumption of 0.18 GPH (gallon per hour) at a 25% load, making it average, for the previously mentioned wattage range. If fuel consumption is your top priority, we suggest to check out the Energizer eZV3500P, which has a fuel consumption of only 0.13 GPH and thus, is one of the most efficient devices in our database.

Price comparison

As you can see from this interactive chart, when compared to other 2500-3500W generators, the Generac iQ3500 is on the expensive side of the price range.

While certainly not the cheapest of its kind, purchasing it would most likely also mean enjoying the reliability of a high-end product.

    Fired right up, out of the box, battery connected, oil and fuel added. two quick pushes on the electric starter swithch and it was up and running.

    + PROS:
    • Simple to set up, start and test.
    - CONS:
    • None so far. It hasn't been stressed tested, yet. Once I get three more extension cords to share power with the neighbors in our condo, once the grid goes out later this fall, will be the real test.
