Great portable Inverter/generator

I'm very pleased with the purchase of this model Generac Inverter. Really like the dual fuel operation and its low noise level. The other features that did NOT disappoint is its mobility to move around with the clever pull up handle, makes it very easy to maneuver as I'm a senior citizen. Also, pleased with having both the electric start and pull start option should the battery get weak/fail. I purchased this to have an emergency backup for electric to our home in case we lose power during stor...

Bought at Menards used for the first time 30 days after and it would shut down when any load was applied, had to get it serviced not replaced. Works fine now but would have preferred a new one not waiting 4 weeks fir a repair

The inverter generator works as advertised. I thought it would start better than it does. It takes at least 4 pulls to get it started. My Briggs lawn mower starts on 1 pull and the generator takes 4 or more. Could be bettered engineered.

Hard cranking

I bought this well over a month ago for use if we lose electricity. Have set it up and started it but nothing else. I hope it works as an inurance policy and prevents us from loosing service. If that is the case, I am pleased I made the purchase. The electric start was a must and that was an important feature when making the purchase. If and when I use the generator, my overall rating could change.

Super disappointed

I bought this on Friday for our tailgate on Saturday. Put oil in it that came with it, filled it with ethanol free gas and never would start. After 3 hours of trying to get it to start we just gave up. Have never been more disappointed in purchasing a product as buying this portable generator. Ruined the entire tailgate

Great for camping!

[This review was collected as part of a promotion.] This was perfect for camping! It powered everything we needed and was surprisingly very quiet compared to other generators I have seen used. Highly recommend!

Efficient and easy to use

[This review was collected as part of a promotion.] The generator is somewhat heavy and I definitely needed my husband’s help to get everything all set up. Once it’s all put together, it is easy to roll around. My dad has a very old generator and compared to that this generator is pretty quiet. It runs smoothly and doesn’t burn through fuel. The panel is easy to read in the instruction manual was helpful. This is a solid unit and I’d highly recommend it as it is easy to use as well.

Camping

[This review was collected as part of a promotion.] This is a smaller capacity generator - best for camping or just keeping the lights on during a power outage. It is heavy, but pretty easy to move with the handle and wheels. It has several different power outlets. We plan to use it mostly for our family's camper.
