I’m always telling my kids they take a lot of things for granted. But I am guilty of it too because I take electricity for granted until I lose it. I’m sure you can relate and you know a generator would come in handy. If you’re here, you are probably shopping for a generator and that’s why you’re reading a couple of Generac IQ2000 Inverter Generator reviews to determine whether it’s any good. 

Well, we’ve wrapped up everything you need to know in this Generac IQ2000 Inverter Generator review. Unfortunately, you may not like everything you’re about to read, but if I were you, I wouldn’t leave anything to chance.

Generac IQ2000 Inverter Generator Noise Level

At 25% load the Generac IQ2000 noise level rating at 23ft away is 53dB. So you can conveniently run it and chat as normal. Your kitchen blender, vacuum cleaner or lawn mower make twice as much noise. So that’s a pretty quiet operation at 25% load. The noise level will obviously go higher as you use more power with the Turbo Mode being the loudest. 

Generac IQ2000 Inverter Generator Fuel Type

The IQ2000 Inverter Generator runs on a 1.06-gallon gas tank able to power through about 7.7 hours of runtime at 25% load. In other words if you’re using 500W, for example, you’ll have a little under 8 hours of runtime before you run out of gas.

What We Like About The Generac IQ2000 Generator

Very Quiet – You’ll barely hear it running if you’re running it on Economy. At 53dBA while on 25% load it ranks above most 2000W generators including the Yamaha EF2000IS and Honda EU2200.

Compact and Portable – The unit weighs 46.2lbs and measures about 3.2 cu.ft. You also get a grip handle at the top for easier transport. It looks rather similar to the Yamaha EF2000IS but slightly heavier. So feel free to take it camping, tailgating, to your job site or just about anywhere. 

Generac IQ2000 Inverter Generator Problems

This is the part of the review where we break down the nasty problems you may run into if you choose to buy the Generac 2000W generator. So check them out below and decide for yourself if they are a deal breaker.

Quits if operating at full load – If you’re planning to use this generator at full load every time, chances are you’ll require a parallel generator or it will keep on going off. Several customers say the generator is simply no good for operating several equipment or devices simultaneously.

It eventually gets loud – While most generators will serve you quietly for a long time, this Generac eventually starts rattling and vibrating annoyingly even while on eco mode. It seems this problem sets in at roughly 200 hours of use. 

Fuel Leak Problems – We came across quite a number of complaints suggesting that the unit leaks fuel at times. It’s not clear where the problem originates from. But all the same, you don’t want to BBQ yourself in the name of finding alternative power, so be sure to watch out for this problem.
