Portable Power

Nothing beats portable power! I have a 12 amp corded leaf blower/ vacuum, and several areas that need my equipment, unfortunately they are just too far for extension cords so I needed portable power, and this is exactly what I needed. It’s not too heavy to move around and it’s very easy to use, Excellent product!

Works very well and is QUIET.

Our power was out for four days and my generator failed. I purchased the GP2500i and filled it with oil and gas. It started on the first pull of the cord. I ran it for the next day and a half to power the refrigerator, TV and some lights. It ran for at least 8 hours on a fill up. I never let it run out of gas but I know it was more efficint than my previous generators.

Awesome Generator

We purchased one of these for our son to use in his bow fishing boat used it all last summer with no issues. We brought it with us up to Lake of the Woods on an ice fishing trip. Temperatures were -25 to -35 degrees below zero. Not one issue. Took it on our next trip to same lake a couple of weeks later. Temps were even colder. This thing purred like a kitten. We have since used thos generator for 4 trips up to the big lake. It runs for 4 days straight on each trip. Not even 1 hiccup Excellent product. Have since purchased one for ourselves so my son could have his back. Also, quieter than the Honda.

Quiet yet powerful!!

[This review was collected as part of a promotion.] We originally didn't plan on opening up this generator until our Memorial Day camping trip next weekend but a downed tree on our power lines at home this passed week changed that plan! We were without power for just one day but with the help of our flashlights on our phones, my husband and I were able to put it together. The Generac iq3800 Dual Fuel portable generator comes fully assembled but we had to make sure the battery was connected, add oil, and then add gasoline. We didn't have a propane tank which can also be used. It was surprisingly easy to assemble since this is our first generator we owned, we assumed it may be more difficult. On the contrary, it took us about 20 minutes to get it ready to go. It weighs a little over 100 lbs but the wheels and handle make it very easy to move around. The digital display makes it easy to see how much fuel we had in there and all the controls are very easy to read and use. Start up is very simple my husband was able to do so on his first try. I like that there is a carbon monoxide detector along with auto shut off if the levels reach danger. That makes it very comforting when using a generator. We used high quality extension cords to thread thru the house and plugged in the fridge, two lamps, one TV, and charger for our phones for the night. Our local electric company had the power back on in about 8 hours and it lasted the whole time. I am very impressed! Especially since the noise level is fairly quiet and we had it on overnight (didn't disturb our sleep or neighbors at all!). Definitely a lifesaver in this instance and we can both highly recommend this generator!

Efficient and easy to use

[This review was collected as part of a promotion.] The generator is somewhat heavy and I definitely needed my husband’s help to get everything all set up. Once it’s all put together, it is easy to roll around. My dad has a very old generator and compared to that this generator is pretty quiet. It runs smoothly and doesn’t burn through fuel. The panel is easy to read in the instruction manual was helpful. This is a solid unit and I’d highly recommend it as it is easy to use as well.

Lasted as long as the warrantie

Did my research and decided to buy a gp3000i, mainly to run the AC on my 28 foot rv. Used it a few times during power outages, etc did fine. Kept a log on how many hours, when it ran last, etc. trying to maximize my investment so the gen would last. Made a cover to keep it clean and protected. Took the trailer on a 5 month trip this year and was using just to run the ac during the heat of the day. It started failing by just quiting. It would restart ok and keep running for a while till it died again. This went on for a week or two. Some days it would work fine, others it would fail several times. Then it would start fine and would die when the ac kicked on, like it didn't have enough power... but we managed to get it running and keep the trailer cool. Then all it broke loose. I heard it cough like a carb issue, then die. Went to restart it and as I pulled on the cord, I saw and heard big sparks inside the cover. Even with the switch on off, when you pulled the cord sparks would fly. 2 years and 2 months after my purchase I called support. They opened a service ticket. Gave me the number of 2 places in phoenix where I could have it looked at. Neither place works with generac anymore. Called service again, 5 location in phoenix would not handle generac service anymore due to issues. Finally one place would look at it, they took my gen and shipped to Tucson where they had a certified tech... Long story sorry, tech calls back said the circuit board is fried, like I didn't know that, and the kicker... it cost more to buy the part then to get a new gen. Also, I'm 2 months over the warranty... The tech , very nice and honest with me, said the gen wasn't worth anything so I decided to discard it.. He recommended I buy a different brand, one more reliable if you can read between the lines. Bottom line, it worked fine, did what it was supposed to do, but was not reliable, then died. For 800 bucks I expected much much more...finding a service dealer was a pain.

Excellent and can be better.

I am a event rental company owner. We rent generators for many different applications. Purchased us to run our restroom trailers which have RV generators. What we really liked about it is that one person could move it. It is very quiet. We would love to see this with an EFI option.

Lots of features

Starts and runs great. Very quiet. However, there is a slight “ticking “ or “ knocking” noise at times. Also it squeals when I plug in a 500watt ceramic heater. No squealing with a heavier load.hoping the noise goes away with use as we don’t have any Generac service in this area. I may take it apart myself. Otherwise I quite like it.

good unit, started first pull out of the box!

It would be usefull to have known the derate info before purchase. The info is on page 5 in the book. 3.5% per 1000ft above sea level is significant at 10,000 ft. If I had known to reduce the expected output by 35% I would have considered a larger unit. I'll still put it to good use and the portability is wonderful.
