Description

Zoom on the Generac iQ3600DF

In a nutshell, the Generac iQ3600DF is a portable inverter generator mostly geared towards:

  • 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
  • Camping and tailgating buffs looking to enhance their experience
  • Professionals who want to be able to deliver results, even during a power failure
  • RV travellers who wish to upgrade their experience to another level

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, and the extra features it benefits from.

Power & Run Time

With its dual-fuel technology, the powerful and versatile Generac iQ3600DF provides an output of 120V. While gasoline-powered, it gives a running wattage of 2,800W along with a peak wattage of 3,600W. While propane-powered, it provides 2,500 rated watts and 3,200 starting watts. In addition, the device is parallel capable (parallel kit (opens in a new tab) not included) and thus, can be linked to a similar or compatible unit for added power.

This inverter generator can be started thanks to a traditional recoil pull-start mechanism, but also to a convenient and efficient electric starter (battery included).

As for its running time, the iQ3600DF, along with its 3.17 gallons fuel capacity, can run for around 13 hours at 50% load with a full tank filled with gasoline (fuel consumption around 0.24 GPH). If propane is used, it can operate for around 16 hours (on a 20 lbs tank - propane consumption around 0.29 GPH).

Featuring a <3% Total Harmonic Distortion (THD), the iQ3600DF delivers a clean sine wave, guaranteeing the safety of your sensitive electronics plugged into its AC outlets.

Outlets

The control panel includes the following 5 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120V 30A (L5-30R) receptacle

Moreover, it presents 2 DC outlets: there's two 5V USB ports (1 x USB-A and 1 x USB-C) with which you may charge electronics, for example mobile phones or tablets, conveniently.

Even if this Generac generator isn't quite RV Ready, it still allows for an easy RV connection via an L5-30P to TT-30R adaptor, thanks to its L5-30R receptacle.

Portability

The Generac iQ3600DF's characteristic encased inverter generator design (L24.6 x W20.3 x H22.5 in) provides an aesthetic advantage and contributes to quieter operation compared to any ordinary, open frame product. This type of design is the most modern and convenient way to recreationally generate power.

Despite its weight of 107 lbs, the generator is still considered 'portable,' meaning it is movable, although its heftiness may restrict portability in certain environments or require additional considerations for transportation and setup. Nevertheless, the restricted maneuverability is counteracted by its set of 2 wheels and its folding handle, enabling easy shifting once the generator is set in place.

Features

Featuring a digital data center on its control panel, the iQ3600DF offers you convenient access to essential information about the power output, lifetime run hours and fuel level, facilitating effective monitoring of its activity and status.

In addition to this info, the light indicators show you if the generator is overloaded and its oil levels are insufficient.

In terms of security, the generator features an overload protection (circuit breaker) and an automatic low oil shut-off, ensuring peace of mind during its use.

The iQ3600DF also benefits from Generac’s COsense® carbon monoxide monitoring. This technology senses and manages CO output and shuts down the unit when necessary, to protect you from CO poisoning.

Alongside the standard documentation and an owner's manual (opens in a new tab) for quick setup, the Generac iQ3600DF is bundled with additional accessories: funnel, tool kit, propane hose and oil.

The Generac iQ3600DF versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Generac iQ3600DF compare to inverter generators of similar power (between 2500 and 3500 W).

  • With a weight of 107 lbs, the Generac iQ3600DF sits in the heavier end of the spectrum among inverter generators rated from 2500 to 3500 watts. If you are mindful of weight, the Pulsar PGD40iSCO is among the top contenders in this power range, with a dry weight of 46 pounds.
  • At 50% load, the iQ3600DF achieves one of the longest run times compared to inverters of similar power, sustaining operations for around 13 hours.
  • Run time is crucial, but it heavily relies on the fuel tank's capacity. Thus, considering fuel efficiency alongside is essential. With a fuel consumption rate around 0.24 GPH (gallon per hour) at 50% load, this inverter generator is one of the more fuel-efficient models within the aforementioned wattage range. If minimizing fuel usage is one of your key priorities, the Pulsar PGD40iSCO is one of the most efficient devices with similar power output, with a gasoline consumption of only 0.22 gallons per hour.

Price comparison

As you can see from these interactive charts, when compared to other 2500-3500W dual fuel inverter generators, the Generac iQ3600DF is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
