    Good Points: Easy start, runs smooth, not hard to move around, lots of output options, VERY fuel efficient


    Bad Points: Loud, oil sensor.


    General comments: I feel the Generac 9777 is good value for the price, works for what I need it to do, and very fuel efficient. It is pretty loud, and my oil pressure sensor went bad, drove me nuts till I just disconnected it, runs fine now.

    It's good on fuel consumption and gets the job done. It's a little to loud for camping or a boat. Overall the Generac Portable Products 9777 4000 Watt Extended Life Premium Generator is a great generator. I have recommended it to friends.

    Starts easy and carries the load. Very reliable although the gas gage doesn't work. The Generac Portable Products 9777 4000 Watt Extended Life Premium Generator got us through a number of several day outages.

    Bought the Generac 4000 EXL generator a few years ago when the local power went into it's third day of being down and I got tired of being in the dark. The unit works as advertised, it always starts fine and the engine, with it's pressurized lubrication and spin-on oil filter (same size and type as the one used on the Mazda Miata and the Yanmar engine on my John Deere Garden Tractor) is a real fuel sipper and it looks like it will last a long, long time. It's big enough to run all the necessitie ...

    My Generac Portable Products 9777 4000 Watt Extended Life Premium generator ran for two hours and died. Metal in the oil pan. Shop fixed it under warranty, but it took 30 days to get the parts from Generac/Briggs.

    I have had the Generac Portable 9777 4000 watt generator for a week now. I am in the middle of the break-in period. To be fair I have not needed to contact customer support. Mine has run flawlessly. I am a contractor in California, and have been using it to power my saws and tools. Today when I went to start my truck, the battery was dead. I was far from any help. Happily this thing has a built in DC port, which charged my truck while I continued working. When it was time to go, my truck ...

    Generac Portable Products 9777 4000 Watt Extended Life Premium Generator - I recently purchased a 4000EXL for Hurricane Francis and Jeanne at Home Depot. I had a problem within the first hour of use. The first thing I did was fill the Engine with oil to the proper level, pull start it through to fill the oil filter, check the oil level again add some oil to top it off, then added the fuel stabilizer and fresh gas. I then turned on the "ON" switch, put it on full choke, hit the start button, and ...

    Generac Portable Products 9777 4000 Watt Extended Life Premium Generator - I don't share the other reviewer's opinion on this piece of junk. Right out of the box the DC voltage was in the 8-9 range. Had it for service twice already with less than 30 hours on it. Totally responsible for blowing our 1hp well pump when it was the only load on the genset.
    Output intermittently crashes under load.

    Difficult to procure oil filter that you don't even know you need until you open the box (which by t ...
