  • I can’t kill it
Size: 1200W
I have to say, I am thoroughly impressed with this 1000w generator. I mean, I bought it for mobile detailing with the intent of upgrading later on. However, I never expected it to be the Nokia phone of generators. I've been beating the crap out of it for two years now and it just keeps going and going and going. I've used it with tools that far exceed its wattage rating, incorrectly mixed fuel, rarely let it warm up before putting maximum load on it, and I haven't serviced the air filter or spark plug once. And yet, it still runs like a top. Even in sub-freezing temperatures, it starts with only a few pulls. It frightens me. I’ve been intentionally trying to kill it, but every night it whispers threats to me in my dreams. It knows when I’m trying to overload it and instead psychologically terrorizes me to the point of sobbing and runs off my tears only to output the energy of the Sun and reliability of a Honda. I'm convinced this thing is indestructible. I'm thinking of putting wheels on it and entering it in a demolition derby just to win the coveted first place trophy desired by rednecks across the globe. Overall, I highly recommend this generator to anyone in need of a reliable and durable power source. Just don't expect to have the luxury of it having a lifetime shorter than yours. It's like the cockroach of generators. On a serious note, it has only had two problems: 1. The power supply wire came loose from vibration and wouldn’t supply power. It was a quick fix (5 minutes). 2. It leaked fuel between the tank and feed line. Again, it was just from all of the hours of harsh vibration. Just needed to take off the front panel and secure the line. This whole generator is very easy to work on in case anything goes wrong and uses universal parts. I highly recommend it. ... show more

  • Feel good I have it
Size: 1200W
Small. Easy to use. Just a few things to attach...took 15 minutes while on the phone. Order oil for the mix with it.

  • Early testing results
Size: 1200W
This cost double what they were a couple of years ago, but still may be worth your purchase. I've only ran it for testing purposes so far. Here are my thoughts. * relatively light weight and small size (what I needed) * a bit louder than higher-end generators. Less noise than a lawn mower, but... * seems to run okay (but it is NOT broken in, yet. I think 5 hours is the break-in period) When I first got it, I took out the sparkplug and shot a little WD40 into the cylinder and gave the starter cord a few pulls to lubricate the cylinder. Added the fuel/oil mixture to the tank then put the ignition switch on and the choke on "start". Gave it a few more pulls to get the fuel into the bowl, then tried to start it. Took 7 pulls to start and ran really rough (as expected). I moved the choke to 1/2 off and let it run another 15 seconds, then slowly moved the choke to "Run". While idling, the rpm's weren't steady at all. I had heard that you may need to adjust the idle screw (which you can see near the pull-start handle, but don't know how you get at it to adjust. Anyway, it settled down, mostly. After letting it idle for about 5 minutes, I ran a 10 watt load just to test the AC power. I then ran a 600 watt load (I couldn't find anything smaller). The motor sags, at first, then revved up to handle the load. I ran it for about 8 minutes, then turned off the load and shut off the fuel. It ran for another minute then quit. I ran the same test today, using my digital watt/voltage/amp meter. Ran the same load as before. Running a 600 watts/5 amps vacuum cleaner, it seemed to run just okay. It was almost, but not quite a steady idle. The voltage fluctuated between 118 and 124 mostly. Near the very beginning, it was really hunting and was between 110 and 130 volts but settled down after a couple of minutes. I'm taking it out for an extended trip, so I hope to get some more experience with it and will update in the future. Cheers! ... show more

  • Get one!
Size: 4400W-Open Frame
I did watch many review videos on different ones and this one is not only excellent pricing, but it is a serious work horse! I use it to plug all my small items in like flashlights, 5 phone chargers, phones, 4 car battery chargers, and this generator is barely working! I'm so happy I got it since I'm homeless and want to get a small fridge as well as other small appliances. I would have taken pictures or a video, but they only allow 30 seconds and my tent is a bit messy right now due to saving for a new tent and set up. ... show more

  • Complete waste of money
Size: 4400W-Open Frame
If I could leave less than one star I would. I was very excited to purchase this generator for my small camper. I used it for a few hours and it ran great. Then after only a few hours the engine shut off and I thought maybe it’s low on gas or something else. I went to check and the check engine light was on and the motor had completely seized. I looked through the user manual and tried all of the “troubleshooting” options and it did nothing. Let me mention I used the correct gas and oil. I followed ever step for the first time start up. It has been two weeks and I am unable to return this product to Amazon for a replacement and I have reached out to the manufacturer multiple times with no response. I am now out the 330$ sum dollars that I spent and I do not have a working generator. The company that sells this product are thieves that sell a horrible product. ... show more

  • Perfect!
Size: 1200W
It's a 2 cycle generator so let's slip the noise part of it. This is just boondocking insurance when I'm very remote so noise didn't play into the purchase. It's light effective easy to pull out of the box crank it up and go. Poor just about 10 mL of two cycle oil into the spark plug hole before you crank it up the first time just to protect the pistons. I used some of the nice premixed fuel and it started right up. Tested multiple different loads including two e-bike batteries simultaneously a very high powered drill and angle grinder and various other appliances that all used 1500 watts or more. You don't want to do it continuously obviously but this little baby can crank out the juice in short bursts or a nice even charge over time. The little DC battery charge attachment is a real nice addition as well. If there's a spot you don't feel like a complete jerk running this thing for 3 to 5 hours you can operate almost anything not to mention power up your batteries for under 200 bucks. ... show more
