When Power Makes the Difference

An average family of four spends between $150 and $300 on groceries each week. Now imagine that food rotting in a refrigerator or melting in a freezer when the power goes out. Having the Generac iQ3500 handy can save the day and keep those groceries from going bad.

By having a Generac iQ3500 on the jobsite, excessive cords can be eliminated, tools can be operated where they’re needed, and no one needs to suffer the frustration of another dead battery.

More than 40 million Americans go camping each year. While it’s great to get away from the hustle and bustle of the city, being completely disconnected can be a real challenge. The Generac iQ3500 will charge your phone, run your fan, or power your whole camper with ease, and its quiet motor won’t disturb your neighbors.

Generator decibel comparison

Even short-term exposure to high decibels of noise can cause tinnitus, or a ringing in your ears. Repeating this effect, like when running a loud generator on a job site or at a camp site can make this condition permanent and can even cause hearing loss.

When you look at a generator decibel comparison, you will see that with the Generac iQ3500, there is no need to fear. Its quiet inverter keeps the volume to a minimum. In fact, it’s even quieter than most conversations.

You can run your Generac iQ3500 without worrying about disturbing neighbors, disrupting nearby wildlife, or damaging the hearing of any of nearby loved ones.

Fuel & Safety

With a 2.6 gallon tank, the Generac iQ3500 has the perfect balance of a long run-time without adding unnecessary weight.

There’s no need to worry about when to refill the tank, either. The Generac iQ3500 comes with a digital display to tell you when your tank is almost empty. It even includes an estimated remaining running time. This makes planning for your fuel usage and power consumption easy and convenient.

Be sure to only use unleaded gasoline in your Generac iQ3500, and remember to store any extra fuel in a certified, safe, gasoline storage container.

Never run your generator without proper ventilation. All generators, even inverter generators are only safe to operate out of doors where there is plenty of ventilation to ensure that dangerous fumes can’t build up.
