Beast

this machine is a beast! it is heavy and powerful and should provide the essential back up power my home needs. The manual for the initial set up was small in size which was a shame as a big machine should equal a big picture. the generator is on wheels but is not easy to move as it is soooo heavy. it also would have been nice if generac offered a custom cover for the machine as well.

Fired up first pull!

Had to put the wheels on but after topping off with oil and gas this thing fired up first pull. It is somewhat quieter than the Stanley that it replaced. Excellent generator for the money. Output seems to be on the upper end of rating. We run power tools and air compressor of it at jobs site. Works great.

Best generator I've ever owned!!

Having had 2 other generators over the last 20 years, this one out-performs all the others. It starts so easy, I really do not need the electric start feature. It has plenty of power to operate the house. We seem to have frequent power losses, so having a back-up is a way of life.

Very Good Unit

No big complaints. Strong powerful seemingly well built machine that delivers consistent power. I ran it continuously for 16 hours on 1 tank @ 1500/2000 watts. With cycling stuff on and off run time easily should go over a day. Things I don't like, battery doesn't charge while running the generator and no fuel drain valve.

Performance is good

I have the 7000E and from what I can see other than the covered outlets and uni handle bar, it is the same model? The only issue I have so far with the generator is that the on/off fuel valve tab broke on me when I was turning it on. Now I use a tiny vice grip to turn the valve. Hard to find what part number I need for the generator b/c I can't find a parts list but all and all a solid generator.

Should do the job easily

I bought it for emergency power for when our tree lined street takes out the power lines. I've only run it for a few minutes so far, to test the breaker box connection. It ran the well pump, furnace, and a few lights without issue. There will be enough power in reserve to keep us comfortable if we have another snow disaster this winter.

Small wonder

[This review was collected as part of a promotion.] Generac GP 3600 is a small wonder. The size is perfect for portability to carry with us on our camping trip. Fuel consumption is plus point, and being able to store perfectly when not in use is another advantage. Additionally i can use it for my some project around my house and as backup in case of emergency.

Great value

Bought this product as emergency back-up generator for home to provide power to refrigerator/freezer and well during outages. Excellent value and dependability. Will upgrade to home standby generator next year to power whole home and move this to garage for powering tools.

Great Portable Generator

A portable yet powerful generator that is well suited for home backup power needs. Wheels and collapsable handle make it easy to manuver. Electric start makes it a snap to fire up. Enough output to protect freezers and fridgerators. 240VAC has enough output to power a well pump.

DEAD unit & useless warranty

WORTHLESS. Unit will not start, presumably due to dead battery (as many others have said) that will not take/hold a charge. Generac said they would replace the battery under warranty but after 6 months and numerous phone calls, the replacement battery has yet to be shipped out from the manufacturer.
