Solid Heavy Unit

I bought this unit last year to run my new 24 ft. concessions trailer G-Dub's Grub which I opened 2 weeks ago. I have worked 2 large events with 20 hrs on meter. It runs the 30 amp service easily-- lights, water heater, water pump, fridge etc. All filters, oil drain, spark plug easy to get to, which is a big reason why I bought it. Getting ready to change to Mobil 1 10W-30 synthetic w/ extra Generac filter sent with unit. I use 89 grade non-ethanol fuel. Multiple power options here folks. Heavy USA made unit. My problem with this unit is it's too heavy for me and staff (female) to handle 390 lbs. Overkill on my part. Just bought extended warranty plan last month. Weighing my options.

Easy setup

It was very easy to setup and it started immediately. I bought this as a backup to use for sump pump and refrigeration. I feel Generac was the safest way to go because if reputation. I can feel at ease when we need it. The sticker with product info needs to be moved to make it easier to see.

General Portable Generator

[This review was collected as part of a promotion.] Living in South Georgia, I need to be ready for hurricane season, and the Generac GP9500E Tri Fuel Generator gives me that confidence. With 12,500 starting watts and 9,500 running watts (on gas), it’s powerful enough to keep our home running smoothly during an outage. I love that it runs on gas, propane, or natural gas—great flexibility when fuel options are limited. The maintenance is straightforward with clear instructions, and the electric start makes things easy. It’s not whisper-quiet, but for a generator of this size, the noise level is very reasonable and not disruptive. The COsense® safety feature gives added peace of mind, and the 7.5-gallon tank provides over 10 hours of runtime at 50% load. This generator is a wise investment for any household facing severe weather. I’m so thankful for this.

This generator is very reliable, started up first time and used during hurricane last summer and 2 times since on short power outages.

Compared several modals, sizes, features, the generac was the best overall. Very reliable, easy to use. Had power through hurricane for refrigerator, window a/c , most house lights, made a 4 day power outage tolerable. Had a 12 hour outage recently, I had just come home from a triple bypass, instructed my wife how to start and she got power to house in matter of minutes. Would not want to be without it.

Great product

We used this generator less than 50- hours. When we needed it again summer of 2020 we discovered the generator burned!!! Very DISAPPOINTED We had to use an older 10- year old Briggs and Stratton that started up right away. We are currently waiting on new generator to be ordered and delivered , due to Covid reasons it’s taken this long. We pray once a new generator is installed it will work great for us for years to come.

Bring on Winter

[This review was collected as part of a promotion.] We live in the country and we have had some hard winters when the electric has been out. We have been wanting a generator for a good while, and finally got one. I didn't know anything about this brand, but "wow"! It had very little assembly out of the box. It is very sturdy and came with large wheels and a handle that uses both hands to keep it balanced, which makes it easy to maneuver. The handle locks in place and folds down when you don't need it. I was really surprised at the features it had. It had 4 plugs, and a 220 volt plug for larger appliances, like a washer or stove. Of course it's not winter, but when the power goes out we will be ready! We hooked it up to our power washer and was able to go beyond what we can usually do around the house. It started with the first pull and had the power to run various items that we tested it with, such as the power washer, welder and we even plugged it into a small camper to run the lights, etc. We are almost wanting a hard winter, just so we can use it. I am very happy with this generator and feel that it will last a lifetime. There is nothing flimsy about it and I think they thought of just about everything with this. I realize we didn't get to try it out for very long, but I can't think of any cons to this generator.

Great job, but heavy and loud

I have used one of these for a back up generator for my house for 5 years and it does a great job, but I have recently purchased and installed a stand by unit 22kw which is awesome., There are a few things that you need to know before purchasing this unit, it is heavy and I have to use a tractor to haul it from my storage shed to the meter to hook it up, also if it is raining I have to wait until the rain slows down because the connections are open to the elements. the only other thing that pushed me to get a stand by is this unit is really loud. I think if you know these things up front and are ok with them then this unit does a really great job providing constant power when in use.

great machine

This is a great machine. I purchased it to run my whole house in the event I need it. It is portable and large and heavy. I bought a small trailer to mount the generator onto for easily moving around, hook it to my truck or ATV. Trailer has room for the big power cord and other extension cords. I purchase a bigger interstate battery to start it. I also use the battery for other things.
