Great product .loved
I am very happy with my purchase. The box was a little beat up, but that's not the shippers fault. I fired it up right when I received it, and just like it was advertised, Very Quite.
This generator has helped & saved us in so many ways already.
I bought this generator after reading the reviews on the duromax generators. I recieved the generator in 4 or 5 days after i ordered it. I was impressed with the packing and the clean detail look of the unit. I was really impressed when it started on one pull. I ran my shopsmith with it and it didn't even miss a beat. Real smooth and quiet. I like it!!!
Big generators are fine, if you have lots of gas to keep them running. I like smaller generators that use less gas. I have a 2 stroke 1000W that runs a full sized fridge and a few low energy lights. I wanted another generator as a backup and to run some larger items, especially a pump motor. I also bought the wheel kit and cover as the generator will be stored outside.
Put the wheel kit on immediately before you add gas and oil, because the directions tell you to turn the generator upside down to do the installation. Make sure you know where the handle will bolt on so you know to put the wheels on the opposite side. The bolt holes line up on both sides and I had to reverse the wheels which took some extra time. The hardest part was taking off the rubber feet. Otherwise it is an easy installation of the wheels and handle.
Next I added the oil and about a quart of gas. The generator started easily once I felt around and found the choke lever. It runs quiet, and with little vibration. It powered several items that took about 2500W with no issues. There is a bit of an odor coming from the muffler as heat burns off some oil left over from the manufacturing process.
The cover is a nice fit and the unit rolls very easily on the wheels. Without the wheels I'd say it is a two man operation to move the generator comfortably. One strong guy can handle moving it, but the position is awkward and risks back injury.
My generator shipped cross country (from CA to PA) and the box arrived in good shape. It just took a few days to make the trip. Free shipping makes a good deal into a super deal.
