Works every time

This Generator starts every time and I have had no problems in 2 years. Shortly after I got this unit I had shoulder surgery. The design of the unit allowed me to set a couple short pieces of 2x4 on top to straddle the fuel line and set the 5 Gallon gas can right on top over the fill hole using only one arm. The only problem I had with this unit was when I let the oil level get too low and the unit would not start without enough oil....good safety catch! I put oil in it and off it went without a hitch. I ran a refrigerator, small freezer, sump pump, well pump, furnace, TV, garage door opener, and some lights with no problems. I have used it several times now when we loose power here in the country and it has never failed me.

BIG....REALLY BIG

This generator arrived in perfect condition. Great packaging and easy to unpack. Assembly of the handle, wheels and rear prop are required. Also the battery hook up and adding oil. Caution (I had to drain some because I rushed the fill and by the time it all settled it was over the fill line) Take your time. There is a replacement air filter and pre-filter as well as a new oil filter provided. Break in period of 30 hours. I have yet to run it but it is really well put together and I will write another review after the break in period. The recommendation is to run the unit for one hour every 30 days. This will keep it charged and ready to go. I would recommend this unit to anyone who wants a whole house generator as it is the largest wattage available in a protable and I don't have propane/lp in my neighborhood. The permanent gas or diesel units of this size are much more expensive.

Runs rough right out of the box

This looks like a good unit. Easy to assemble and started up with no problems but ran very rough and stalled. Needed to call for service to come tune it up. Im sure its something minor like bad gaps in the plugs or something like that but a brand new unit should run for a few years before giving you problems. Don't know what this means for long term reliability.

This product had all i needed for what i needed it for .

Dealer was great (electric generator direct). i would have given this item 5 stars but pull cord did not work correctly after 5 to 6 pulls . i had to get it fixed (for free) but little bit of a pain ,but runs all that i need to run ,best part is its on wheels so i can take it any where .

If it works it works. But that's if it works

After long storage battery dead. Customer service said had to disconnect battery we will ship a bra one. Well off days off storage so it should cut off the battery. I read the manual says on will drain it turn off. Nothing about discount. That was last fall. Took battery out Month ago one start was great left battery in month later won't start. Even with new battery. Plug is super dirty and chipped. Got a new one to put in this weekend. I am sure it's going to be a tough start. Now does a plug get so dirty on 38 hours of use? Going to change oil too. Don't know where fuel filter is either manual won't say and it doesn't look like a car filter. Also that list the part number for the plug but can't find out what type. I thought generac was a good brand. I was wrong. I wish I got a different brand that just starts up. I lost everything in the fridge because this refurb can't start past 38 hours of run time. Right now it turns but doesn't turn over

Good value

Bought for emergency use only, to power a sump pump and maybe a gas fired heating system in winter. Used only once so far, to help a friend during power outage. It started up easily. They were able to run their heating system (hot air), which was nice because temp was down to freezing at night. Since then I tested it one other time during mid-winter, to make sure it would work in cold weather, and it started up no problem. This unit has one duplex outlet with 15 amp breaker. Only enough power for essentials, but that's all I wanted. It is relative small, and one able bodied person can move it if required.

I spit in Hurricane Sandy's eye!

This is a good unit for the money as it ran well with no hiccups. The only issue of significance was the 5-gallon tank, so we had to run the unit in intervals while we searched for gas. But this unit has good features with a clear fuel gauge, the electric start with pull-cord back-up, the included battery, charger & the wheels (some co.'s sell units with wheels as an option) and a run-time meter. Minor inconveniences included the needed oil change after a short run and having to play with the choke on start-up.

Excellent quality and features for the price

I bought this generator on the recommendation of a friend who has this same one and from all of the positive reviews that I have seen online.Upon receiving the generator,the only thing that I had to do was (easily) install the wheels and handle,connect the battery and fill the oil(included) and gas.It started right up.I really like the electric start feature,my wife will be able to start it if I'm not home.I haven't had to use it yet in a power outage but now I'm ready.

Very good product - easy to setup and use

I compared several different generators and chose a GP6500E - which I am very happy with! The intial setup took under 30 minutes, and it started right up. The durability and ease of use seem very good, and the electric start option was well worth the money. I would highly recommend this product.

Very powerful!

[This review was collected as part of a promotion.] This generator was bought to power my house during a power outage. It is easy to set up. The directions are simple-you don't have to be a handyman in order to put it together. It comes with the first supply of oil. You just open it up and pour it in! I am extremely happy that it has a push start. I am a very small framed woman and I was afraid that in an emergency situation, I would not be able to start it on my own.(with a pull start) I was able to push a button and bam power! It is quite heavy, but it's not hard to wheel it where you want it to go...and with the never flat tires, you won't have to worry about getting it stuck with a punctured tire. This generator is very powerful. I was able to power our refrigerator, the neighbors refrigerator, two TVs, a deep freezer, a computer, two fans and lights. It's not as loud as I thought it would be. About as loud as a lawnmower. This thing ran for TWELVE STRAIGHT HOURS! That's impressive! Bottom line is... buy this Generac! Don't buy a knock-off brand to save a couple of dollars. It will not have all the features of this Generac. It will not be as durable or as reliable. You will not be able to power the amount of things this Generac does and it will not run as good or as long!
