Generac iQ 3800 Starting / 3000 Running Watt Gas and Propane Dual Fuel Inverter Generator

Reliable and quiet

We were without power for 11 days And our generator did a fantastic job

Good generator - poor warranty/service

Overall happy with the generator however, battery was defective right out of the box, to have it replaced under warranty was very slow and required me to drive 30 minutes to the closest dealer... Twice

We purchased a few months hoping to be somewhat prepared for extreme heat in case power goes out as usual. This time we were ready. I got a little excited when it went out the first time. Plugged in the refrigerator, TV, cable box, 3 fans and one light. If I only had a way to connect the AC. Power has gone out twice, one for 3 hours, one for 9 hours. The unit did not miss a beat AND my neighbors did not know I had been running a generator

Great Purchase

My old generator died on a camping trip. My forced upgrade to the Generac Generator was a welcome addition to our setup. Quiet, easy to use, and light.

electric starter and pull start combo, ease of use

before I purchased your product, I did my homework. it filled my needs of an inverter. not to much but just what I need for my purpose. it exceeded my expectations. the dual fuel, and the whispering sound!! awesome product

Pretty good but seems to need high octane fuel

Initially I was extremely pleased with the GP2500i portable inverter generator during my first 5 day outage in June 2026. It was relatively easy to start and I used it to recharge my lithium power supplies which were supporting my essentials (fridge, sump pump, a few lights). Then in August we had an 11 day outage due to a derecho resulting in a multiple county widespread damage and power loss. It worked fine for a couple days but then started struggling, even shutting down. Oil was fine, ca...

Couple Issues

I bought it in May 2026, i have had a couple of issues. The electronic start button stopped working. When I use the propane system it shuts down are a while for no reason.

CO sensor works great

Purchased the iQ5200 several months ago. Nice quiet generator, just remember to point the exhaust away from the walls or the CO sensor will shut it down I finally figured that out ever since it’s running like a CHAMP.

Barely Adequate Generator

Many problems. First generator I got from the store was horrible. Nearly impossible to start, died 10 minutes after starting it, then when I tried to restart it the starter cord broke on the first pull. Returned that one and got a second one. It runs but lags heavily on the voltage increase and doesn’t manage to get up to its minimum rated voltage. Forget the peak voltage, it cannot peak at the minimum. Then let’s talk about the instructions. It has two different ways listed to measure the oil, ...

Disappointed

I thought the peak power would allow my generator to start my AC unit but it did not.
