Rated 1.0 out of 5.0 by Would have been a 4.5 star except.... Liked generator, would have been a 4.5 star , except..... Getting it repaired less than a year later has been a problem. January 20, 2015
Rated 3.0 out of 5.0 by Here's what you should know about the Generac GP3250 that the sales literature doesn't tell you: 1) There's no hour meter (the claim on the home depot website is false). 2) The unit comes with a 14Amp fast-blow circuit breaker. Consequently, it WILL NOT provide the full 3250 Watts to a single 120VAC load (such as the furnace blower I'm trying to run). Not even close. My furnace only needs 6 Amps to run, but it needs 22 Amps (2640 Watts) for the first 2 seconds upon startup of the furnace. The generator's 14 Amp breaker trips before the furnace starts. Strange that the furnace works on a 20 Amp hydro panel circuit - it must be a slow-blow breaker. It might provide 3250 Watts to several 120V devices spread over its 2 circuits, but I haven't tested it. In all other respects, it seems like a good generator. February 2, 2014
Rated 5.0 out of 5.0 by Great Product Great Product start on the first pull very eazy to handle and assembly. Runs all my DJ equipment for outsides tailgating events. No matter what team you are cheering for you can always depend on the Generac to start. It rans for more then 8 hours without putting fuel in it. I would reccommend this product to any one who as an outsides event that needs power. Nothing runs like a Generac. The best thing it not nosiy at as others I have heard. October 22, 2015
Rated 4.0 out of 5.0 by Just unpacked and started right up Brought home from the store today. Easy assembly. Started after a few tries and we ran it for a while too test. Good product for the money. Electric start would have been a plus. But bought as a backup for home, probably will run it once a month to excursive it. October 14, 2015
Rated 4.0 out of 5.0 by Works great This was bought for business. I would purchase one for personal use as well. October 13, 2015
Rated 4.0 out of 5.0 by easy to use! Works great! Easy to put together and started on the first pull! October 3, 2015
Rated 5.0 out of 5.0 by Great product A quiet and provided enough power to run all the power tools needed in the woods. September 30, 2015
Rated 5.0 out of 5.0 by Reliable . Easy to maintain. Starts everytime. All outlets give excellent power generation. Seems very efficient on gas. Cons: 1. Does not have a voltage regulator for connection to furnace. 2. Fuel gauge is very hard to see at any level. 3. Is not powerful enough for interface to Main power line with special interfaces. Requires 4000watts min. September 10, 2015
