    • Easy start !
Style: 4000Watts
Wow delivered in Two days. I bought for my camper. It's a 30amp. Does not come with oil. Runs the camper in eco mode with heat fridge and freezer easily. Doesn't kick up in revs. I'm sure with AC on it would. To cold to try.. starts easily.. For the price and quality I'm very pleased.

    • Runs
Style: 4000Watts
It runs. Not the most efficient thing Plug in a car battery charger, to a marine battery. Then use a pure sine wave inverter. This way you have power and your not wasting watts by using one of the two outlets.

    • Great buy would by again fast delivery
Style: 4000Watts
I was suprised when it came so fast it arrived in 2 days from this seller! The generator had 1 tiny dent on the frame but nothing that affected the looks or function of the generator the box wasn't damaged probably done in manufacturing. I put oil and gas in it and it started first pull. Just be aware on the choke for generator is backwards from the way we think the choke operates , off means choke is actually on and on is the run position. ... show more

    • Will not start cold without using starter fluid.
Style: 4000Watts
Will not start cold without spraying starting fluid in the carburetor. Once it warms up, it starts on the first pull, and works fine. Got the extended warranty, thinking about returning it for an exchange if the warranty allows it. Otherwise I am satisfied with it.
