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.

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.

defective, had to have it repaired with less than 1hr run time- disappointing!

although this unit is the perfect size and wattage for camping, I had problems from the start. Literally the second time I started the unit, it would not shut down when switching to off position. I had to choke to shut down. After returning from its maiden camping trip, I was lucky enough (with Generac's help) to find a repair shop that replaced the defective part. A lot of waisted time and effort to repair a brand new generator. I will probably never buy another Generac product. Colorado Camper .

Realibility

I bought this generator because of its realizability. We lived in NJ, during both hurricane Irene in 2011and hurricane Sandy in 2012. In both storms we relied on a Generac generator for solid performance for over two weeks without electric. This was huge, as we owned a dog kennel in which we were able to keep going, helping a lot of our customers care for their pets. Tom

Very quiet

I purchased this to use at an off the grid tiny house and really wanted something quiet. This works perfect for a quiet power source. The only thing I’d like to see addressed is having the oil drain out of the bottom instead of the side. The side drain isn’t very user friendly.

Overloads for no reason.

I bought this unit for a month long trip. This thing turns off after a very short time displaying"overloaded" no matter what you do. I tested it with just a 1500 watt coffee pot and same result... "overloaded" Very dissatisfied with this product as it left us without power for a majority of our trip which was 80% dry camping. Don't recommend

Good features and quiet running.

Love the new generator, with an easy start electric starter. I went thru the process of adding the oil, etc. The generator arrived with a dead battery. I charged the battery , it started and ran quietly and efficently. l started the generator once a week just to keep ths system operational. My only problem is I need to charge the battery every time I go to start the generator. The battery does not hold a charge. The battery arrived needing a charge, and every time I go to start the generator I still need to charge the battery again.

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.

Love this generator

I was on the hunt for a generator for my RV. I wanted one that would easily run my AC in my camper and not be maxed out. I found this one. It’s exceeded my expectations. I ran the generator in the bed of my truck while I slept in my camper in the parking lot of a cracker barrel’s parking lot. It was so quiet that I only heard the generators from the Motor homes around me. It kept my AC running all night. I expected to wake up to a generator that was out of fuel. I was surprised to see that I still had 50% fuel remaining when I woke up, and the generator still running. I love that you can’t hear it when you’re 10 feet away from it inside the camper. This is why quietest little generator I’ve ever owned. It’s powerful and efficient. I couldn’t ask for more in a small generator.
