The media could not be loaded. Item shipped and arrived four days prior to projected delivery date. I ordered this generator on a Tuesday, after finding no generators were available locally. The January Ice storm was forecasted to hit TN on Saturday, January 24th. Projected delivery was Wednesday the 28th. But I ordered it anyway as we live in the woods at the end of the power distribution grid. To my complete enjoyment, my two German Shepherds woke me at 8 AM Saturday morning... I made it to the front door just in time see a young lady plop this generator on my front porch and march away. In a fortuitous turn of events, I had the day prior located generator cords that I had made for the ice storm of 1994, so I was somewhat ready. I brought the generator inside, unpacked it and breezed through the owners manual... I am pretty familiar with generators having retired from a long career of maintaining generators at remote telecom sites. The biggest prep with this generator were the small shipping brackets on the bottom of the generator. What a pain. The four inside bolts are hard to reach as there is not enough room to get a socket on them, an open end wrench is the only thing that will work and one is supplied but i used my own. And unless you have very strong fingers, these bolts have to be wrenched to whole way out, and you are lucky to get a quarter turn on a wrench due to the tight quarters. But after that, things went well. Be prepared to have a quart of 10W-30 oil on hand to fill the crank case. You need about two third of that quart, roughly 20 ounces. An offset funnel is supplied for oil fill, its awkward but it works. I filled it up with gas and it started right up on the third pull. (!) I ran my double male ended extension cord from the generator to an outlet near the TV and wood stove blower motor circuit and waited for the power to drop. At 4:02AM Sunday morning we lost power. Trees were falling everywhere, sounding like a war zone. I killed the main breaker, shut off all 220V breakers and tried to start the generator. It was so cold that you could feel the thickness of the oil in the crankcase, but it started on the second pull. Be sure to have your cord disconnected prior to starting. The choke lever is a little awkward, a little hard to find and feels a bit fragile but you get used to it. Once running smooth, I plugged in my extension cord into a 120V generator outlet and then went inside to plug it into the wall outlet. Twala, we ended up having power to the wood stove blower, TV, refridgerator, microwave, a small space heater and more than enough lights. All running smooth. We did turn off the space heater when using the Microwave just in case it proved to be to much of a load. We ended up using this generator non stop for over four full days, even doing "in flight" refueling methods. We ran the power cord through a window and used painters tape to keep cold air from coming in through the window crack, this worked nicely. One time at night in the wee hours I lost track of run time and it ran out of fuel...outside temp was in the low teens. I refueled the generator and it started back up on the first pull. And it pulls pretty easily. One thing to note is that this generator is a bit on the loud side, so I moved it to behind my truck about 25 feet away from the window and this proved to be the hot setup for sound level. The exhaust output port on the generator muffler is threaded, so additional mufflers could probably be added with minimum hassle. Note that all generator outputs are 120V. I had it in my head the the twist lock plug was 220V but it is 120V. This little generator made it just in time to make this ice storm a whole lot easier to deal with and I would but it again. This may not be a Honda or Predator unit, but it makes just as good power - and better priced.. As for run times, this of course depends on the load. We averaged around 5.5 to 6.5 hours. We could get close to 8 hours run time when the TV was turned off. Not too shabby. I think you will be satisfied. And I really need to mention the seller, who got this shipped out quickly! Thank you.

This generator is exactly what I was looking for. It feels sturdy and well-made, with a strong metal frame that looks like it can handle regular use. Everything arrived in good condition, and setup was simple. It starts easily and runs consistently without any hiccups. Power output is stable, and it handles basic appliances and tools without a problem. I also like that the fuel tank is easy to access and refill, and the overall layout makes maintenance straightforward. Noise level is what you’d expect for this type of generator, not silent, but not overwhelming either. For the price, performance, and reliability, this is a great option for backup power, outdoor work, or emergencies. Very satisfied with this purchase and would recommend it to anyone needing a dependable generator

This portable generator is an excellent purchase! It’s reliable, easy to use, and starts up quickly without any hassle. The power output is strong enough to run essential appliances, lights, and electronics with no issues. I really appreciate how compact and portable it is—easy to move around and store. It runs smoothly, isn’t overly noisy, and feels well built and durable. Perfect for power outages, outdoor use, or backup at home. Definitely worth the money and highly recommended!

So, I purchased this generator 4 months ago. I finally used it for my first tailgating opportunity and it was only running one 24 inch TV. After about 5 hours it started shutting down. After restart it would shut down again in 10 minutes with the overload light flashing red as it shut down. When I called Amerisuninc on September 7th to ask them about this problem, I was told that running it for 5 hours was a long time and that I shouldn’t run it so long as it gets hot. Really? It’s a generator and many generators around me on the same day I was tailgating ran for 10 hours or more with no issues. So, if my power goes out and I wanted to run my refrigerator, I better tell the power company that I only have 5 hours and they need to have my power back up by then. What a joke, I have never heard a manufacturer say that about their product - in this case a 2200W generator. Worse response ever and worse product I have ever bought. Please get a Ryobi, or Honda, or some other more reputable brand than Amerisuninc. I would like my money back as no where in their brochure or in the description do they ever mention this limitation. The brochure even says at 1/4 load it can run for 10.5 hours. Go figure, that’s a straight up lie! This happened again with using it outside to run my electric chainsaw. After running it for a few hours (on and off) it started shutting down again. It is truly a worthless generator.

Machine is very portable which is handy. Overall for the money I’d say it’s a good value but since there was not a decent review to help me make my purchase I figured I would write one: Very sensitive to completely clean gas. Used fuel from old gas can and started dying and cutting out until I cleaned carburetor, does not appear to have an inline fuel filter which would probably help. I use it with an adapter to power my 34ft camper. It will handle all of the lights and everything just fine, will run one of the AC units, but can not do AC and run the microwave or coffee maker at the same time (which was to be expected). Stayed running for about 9 hours per tank of fuel. Only reason I am not giving it 5 stars is because of the lack of fuel filter and I do not think it actually puts out the listed wattage.

The media could not be loaded. Great purchase, powers the entire house. I washed in the machine with it. It burns gas and oil really good. It isn’t as loud as I would have imagined, it is easy to operate I can start it and turn it off on my own. I even ran it longer than 6.5 hrs. I would recommend to purchase it!
