A steal

It is well built and arrived in good condition after coming from California to South Carolina. Assembly was very easy although the manual needs come correcting. I will always run mine on propane as I have had experience with hurricanes and emergency generators and finding and storing gasoline before. Propane can be stored indefinitely without deteriorating and you don't have to clean out the tank and carb. after each use. The only thing I feel that is missing is an idle position when the generator is unloaded. I run 2 refrigerators and switch off to an A/C unit if needed but these all cycle on and off and it seems wastful for the genset to be turning 3600 rpm when unloaded.

Other than that it started on the first try with propane fuel, handled the loads I put on and never went above 69 db noise level (according to the app on my cell). It is put away and I hope I never have to use it. Just have to remember to charge the battery every few months if I don't want to crank it by hand.

very good generator

was hard to get the shipping plate off as we are older and not much strength but friend helped and it is very quiet running and easy to start my husband thinks its great and he is 80 yrs.old

Don't be shy about the quality of this produce

Product arrived in four days via FED EX Ground in great shape. Well boxed for shipping with padding. Easy to assemble, battery was fully charged, added oil, hooked up LP gas and it started right up. Very quiet compared to past units I had. It is nicely finished. I wanted something for storms to run my side by side and a window ac unit and this fits my needs. Like the fact that it used three types of fuel. Customer support was terrific when we checked order/shipping since we had a storm coming at us. Do not overlook this dandy unit.

Everything I expected (well not at first)

Product arrived packed well. Started up easily on propane. I have not gas yet. I plugged my travel trailer in and the generator breaker tripped when the A/C compressor kicked on. I emailed the service department, Matthew told me how to correct the problem and my generator does exactly what I expected it to do! Wasn't a problem with the generator, it was a problem with my adapter cord not being compatible, yet he still helped me through it. Great product and great customer service!


I purchased this generator last week and it arrived within the week. It arrived with some small dents to the frame from shipping, but no structural damage to the main components. Not a issue. Today, I ran some function testing to see how well it will perform on the house during a power outage due to summer storms/hurricanes. Following the manual instructions and using a propane setup, the generator fired on the third attempt from the key start. i used the 240v connection, plugged into the transfer switch. I threw on each breaker 1 at a time so I could see/hear the load. No problems at all. This generator does EXACTLY what I intended/wanted. It will supply power to entire home(2000 sq. ft), with exception to the central ac unit. During an outage it will supply more than enough power to run all my essentials at the same time, the refrigerator/freezer, water heater, lights, tv, a portable ac unit and fans without a problem(my stove is gas). Keep in mind that during an outage, I dont need every light on at once, just the essentials to be somewhat comfortable. I have a 10,000 watt gas generator if i want everything in the house running at once. This generator is definitely quieter than most I've run across. I put it in the storage room, closed the door and can barely hear it running. I can't hear it running from inside the house or from the street(60 ft away), which I like alot. Draws less attention. It also burns much cleaner. I can hear my 10,000 watt generator from the end of the street and everyone for several blocks knows it's running. I am quite pleased with the performance of this generator and I am confident it will satisfy my need for power in the event of an emergency. The wheel attachment makes it very easy to move around and portable enough to just throw it in the back of my truck with a couple propane tanks and take it anywhere. Now, i'll have my propane provider run a line from my large tank in the back yard to my storage room so that I will always hav...
