    • Just what doctor ordered...as say.
Set name: 4000 Watts
6/16/2026 put in oil gas, put in choke, 3-4 pulls and cranked right up, in about 5 minutes turned off choke ran smooth and surprisingly quiet. Tested plugged in ran 1500 watt hand drier and frig and freezer no strain no problem. Son has open frame 4500 watt very heavy and loud. This one can pick up and load in vehicle or carry short distance. Perfect quiet running for my house in subdivision with small lots so won't disturb neighbors. Fast free 4 day delivery to NC. Great buy and product. ... show more

    • Quiet and efficient
Set name: 4000 Watts
Runs my RV off grid without any problems. Runs almost 9 hours on less than 1 gallon of gas at night. Really quite so sleeping made easy.

    • It'll be great for camping
Set name: 4000 Watts
Right out of the box, they already had it full of oil and gas for me.... 🤣 Jk, I added oil and gas, fired it up, was instantly happy with how loud it was, barely had to yell over it ... jk, we could hold a normal convorsation over it easily, tested it on an oven I had sitting outside, worked fine, tested on a dehydrator, a pressure washer, with my phone plugged into it the whole time, works great. Now mind you ive has this product for all of an hour, but Im already confident I'm not guna have any real issues with it. About to change generally they say run it for an hour and change the oil, I already threw the Manuel to my fire pit as soon as I opened it, so maybe not copy me, but I'm sure it'll be pretty standard stuff. I think this was a good idea. ... show more

    • Quiet and easy to operate, but wattage rating is misleading.
Set name: 4000 Watts
I really like the design of this generator and it works great other than wattage rating is very inaccurate. It is nice and quiet and easy to operate. I have an AC unit that draws 1,600-2000 watts and this generator that is sold as a 3600 w Dies and gives overload status on the control board when I turn on the AC unit. Additionally, after purchasing the generator for this AC unit on my trailer, I find out that it is not returnable... So I guess I'm stuck with it and still have to buy a bigger one to run my AC. So beware of the wattage rating and buy something more than twice what it calls for if purchasing this brand. ... show more

    • Works every time and great on gas per hour. I would definitely order this again
Set name: 4000 Watts
Don't wait until you need it to get it. I've had mine for a little while now and I have to use the heck out of it. It has run flawlessly. I'm thinking about it ordering another one for my dad.
