For Camping

Just bought this generator and I am so pleased. It is exactly as described. Runs my whole camper 13,500 BTU AC all lights etc. Runs nice and quiet. For the money I haven't seen a better product on the market. Comes with all you need to get started including a funnel to put the oil in the generator. I invited my neighbor over to check out my new generator for camping and he's already left to go order one online like I did. I'll come back and update this review after a few months of use and let you know if I am still happy with this generator. Thanks Generac for what I believe is going to be an awesome generator from what I have seen thus far.

Tickled pink!! This generator is awesome!!

generac.com

I like Generac generators they are nice and quiet more or less some of the quietest on the market and then I got one of the 5200s and it is very quiet for its size but then it started having issues I had to take it to the shop a couple of times but Generac came through they actually gave me a new one  was not expecting that but I'm glad they did so I still like Generac if you want to quiet generator that's not embarrassing to run then you need to get a Generac

I'm still glad I got a Generac generator

I got my iq5200df a couple of months ago and have used it once when we had a 16 hour power outage.  I ran it on propane and it performed beautifully 
 It allowed me to run 2 refrigerators and a freezer simultaneously and still watch tv.  I'd unplug a refrigerator and then plug in the microwave or coffee maker,  toaster or whatever so I had all I needed to have running when I needed it. The push button start instructions could be a little clearer but I figured that out. It seems like a top grade machine so far.

Used it once so far,  it did great!

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.

Great Purchase

I am a very senior citizen and have limited strength. I purchased this electric start so I could easily start the generator when needed. Haven't needed it yet but it starts each time I test it. I had a manual start Generac for years that worked always when needed. Very good product.

Ready for the Hurricane Season

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

Been using my generator for about a month now. I use it to power a 5000 BTU camping air conditioner. The only issue I have is that there is no way to turn eco mode off and when the compressor starts it goes into safe mode and shuts down because the automatic eco shutoff doesn't give enough power fast enough. I added a small fan that pulls about 95 watts to increase the idle slightly and now it works great. Also I wish the fuel tank was at least 2 gallons.

Works great after some engineering.

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, cap was not so tight as to restrict gas flow.  We poured out the gas and filled with fresh; no improvement.  I was using regular gas, 87 octane with 10% ethanol.  Non-ethanol gas was not available.  Additives to address possible moisture may have helped a bit but not enough.  I finally switched to highest 97 octane/10% ethanol fuel which did the trick and the generator ran reliably. So in future when needed I will use high octane gas.

Pretty good but seems to need high octane fuel

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, no break-in instructions and is very weak in almost every other category of maintenance. Incredibly minimal for a company with as much history as yours. Maybe you should drop Vietnam production and bring it back to the USA.

Barely Adequate Generator

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

Good generator - poor warranty/service

Purchased a Generac inverter generator on 4/26/2026. Would not operate from the first try. The generator would not run for more then one minute at a time then stall. It has been at the repair shop since.

Disappointing purchase
