Needs a load meter

during recent power outage, the generator work efficiently, running 9 hours on about half a tank of gasoline. However, lacking a load indicator, I had to closely monitor gas usage because I didn't know how much load was being carried so I couldn't know how long the tank of gas would last (based on the literature noting the tank of gas would last approximately 9 hours at half load) This is a great machine, but without a load meter it must be monitored nearly constantly lest it run out of gas...

I cant give a review since I have not been able to check the equipment.

Gas tank leak right out of the box. As soon as I poured gas into the tank it start running out.

Verified Purchase

Fantastic Generator, Great Price!

Absolute beast! This powered everything I needed to stay warm, and use our essentials during a winter power outage.

Generator Review

so far, the product has met my expectations. the setup was fairly easy. It would be nice if the manual print had a larger font. It would also be nice if the generator came with a wattage meter.

Reliable and Powerful generator.

[This review was collected as part of a promotion.] This generator came almost fully put together. Super simple instructions for putting together/use and I love how powerful it is. It's easy to fuel up and set up the controls aren't to complicated. We used it with multiple bad snowstorms this last year and it never let us down. Would absolutely recommend and it's worth every penny.

It starts and runs great. The only problem is it is missing a pin for the handle. I called Generac and talked to a person and he said he would ship one pin and never did.

Awesome

I bought this after a heavy rain storm that knocked out the power. No power, no sump pump. Heavy rain forecast for the next day. Fortunately the storm passed without any issues. I am ready for the next storm.

Great machine, choice of running on three fuels

This has been the best generator I have ever owned, so far have run it only off propane. No gas going stale in the tank best choice I have ever made!!

I purchased my Generac generator at Ace Hardware in North Webster IN on March 13th, 2026. I have used it 3 times since then. I am extremely happy and satisfied with my purchase. Thank you.

The real deal!

This is the real deal. My 16 year old Storm Responder was getting tired after many hurricanes and power outages then Beryl hit us hard. Time to upgrade, Picked this thing up from Sam's on sale. Had to drive to to Lake Charles to find one in stock but Curb Side pick up worked flawless. I pulled up, they tossed it in back of my truck and I was on the way back home. Took about an hour to assemble because directs were poor at best. Started instantly the first time. Ran the next 100 hours strait stopping only for fuel and oil changes. I have a 30A transfer switch on my breaker box. Running a 12k BTU window AC unit and the rest of my 1800SF house minus the central AC unit was a breeze. Fuel usage was about 1 gallon every 2 hours. About 6 gallons each 12 hour fill up. The only feature I wish it have was a usage/demand meter to see what the load is but it NEVER struggled. Buy this one!
