Great Generator with tons of power

Bought this generator to power four refrigerator/freezers in the event of power loss. It performed like a champ for two days straight. More than enough power for the four plus lots in reserve. It is a heavy generator (200+ lbs) to move, but I can live with that considering the fantastic oversized wheels and well designed handles to move it around. After putting together and filling with oil and gas (approximately 30 minutes), it took only two pulls of the rope to start. Electric start was not used because battery was low. Charger for battery did not seem to charge enough to use electric start. I would recommend having a portable jump starter if you plan to use the electric start. Quieter than I expected when running. Hobbs meter to view total operating time is a great plus to know when to service. Well designed circuit breaker for the multiple outlets. Bottom line -- this is a great value generator that I would recommend.

Power to spare

I bought this during the power outage of August. Setup was easy, the generator worked flawlessly. It powered half of my house with extension cords. 2 refrigerators, a chest freezer, sump pump, ceiling fans and lights. Had my cable modem and wifi running as well as 2 8,000 BTU air conditioners. The only issue I ran into was that the cushions for the handlebars were missing. All it took was a few emails and Generac took care of that for me.

Pleased with our purchase

We lost power due to severe storms that roared through our area. The sump pump was flooding out into the basement and we had just filled our freezer so we needed electricity. Because of the widespread damage from the storms it was evident we were not getting our power on anytime soon. Purchased a Generac 8000 watt unit and we were able to get through the blackout! The generator supplied more than enough power and ran several hours on a tank of gas - very pleased with our purchase!
