Style: GM2800iSAC
I couldn’t be happier with the GENMAX GM2800iSAC! I bought it for camping trips and to use as an emergency backup generator, and it’s honestly been a game-changer. What I Love About It: ⚡ Plenty of Power – This little generator has more than enough juice to run my 5,000 BTU AC, lights, and all my small electronics (phone, laptop, etc.) simultaneously without breaking a sweat. The clean inverter power means I can run sensitive devices with zero worries about damage. 🎒 Super Portable – Weighing only 45 lbs, I can easily carry it from the car to the campsite. The handle is solid and makes it easy to transport, even when it’s fully fueled. 🔇 Surprisingly Quiet – It’s definitely quieter than traditional generators! We were able to have normal conversations standing right next to it. It’s not “silent,” but for the power it provides, it’s impressively quiet. ⛽ Great Fuel Efficiency – The runtime is awesome! I’ve been getting around 6–8 hours on a single gallon of gas at partial load. That’s perfect for longer camping trips or power outages without constantly needing to refuel. 🛡️ Awesome Safety Features – The CO Detect sensor gives me peace of mind when using it indoors or in semi-enclosed spaces like the garage. I love that it automatically shuts off if unsafe CO levels are detected. Final Thoughts: For the price, this generator punches well above its weight. It’s powerful, portable, and built with safety in mind. Whether you're camping, tailgating, or just want some peace of mind during power outages, this generator is a fantastic choice. I couldn’t be more satisfied with my purchase—highly recommend it!

The media could not be loaded. UPDATE 2: It has now been 2 years and 6 months since the purchase of this generator and it still runs great. It still only has about 80 hours on it, averaging my use to 32 hours per year. This unit is now at an even LOWER price than when I bought it making it a better deal. I make sure to use ehtanol free gas, run it for 30 minutes a month with load and change the oil every 40 hours. I would still purchase again. UPDATE: I bought this generator in April of '22 and it is now November '22. The generator has been great all summer and went on several trips to power our 22' camper. With the hour meter I installed, I've racked up 40 hours of run time and its worked great, running the trailers AC and anything else we've needed. I still recommend this unit for the money. I'm also getting about 4 hours of run time with heavy load. I’m going to compare this to the Honda eu2000 I’ve had experience with and a Wen4500 that I recently bought. -You wont find more generator for less money than this right here- This gen will run 2800 watts continuously (on the upper end) and will surge 3000(or 3200) depending on if you’re looking at the box or the machine. If you’re curious what it will run, look on YouTube. Gavin’s garage has a great video of its capability. This thing is quiet - my Apple Watch shows around 59-61db at 23’ in grass. Mind you this is on eco, but it’s about as loud as a window AC from that distance. It’s touching Honda territory with more wattage. For this price and wattage, you can’t get any better. I’ll be using this at camp grounds to run a 13,500btu camper AC and some other items. This is also a nice backup in case power goes out. My previous gen, an open frame Wen 4500, had all the power I’d need and about 20 more db’s. Most campgrounds don’t like that so this genmax is perfect. As far as portability goes, full of gas it’s about 56lbs and is easily totable with the handle up top. If you’re looking for a strong and quiet generator for any occasion, this should be on the list. Granted, it’s cheap price may mean parts are not as durable compared to a Honda, but most of the internals on these generators are made in bulk and just rebranded. I’ve had zero issues yet. One thing I do wish this gen had was a display with some info. I went ahead and installed a runlead hour meter (8$) on the top. This allows me to see how much runtime the machines had for break in and oil changes. I did a lot of research over a two month period to find the right gen for my needs and this fits the bill in almost every way. If you’re on the fence, buy it!

My Genmax 1200i was delivered yesterday. The packaging was in good condition. The generator was securely packed. Everything was in the box that was listed. I added oil and gas. It started I believe on the 3rd pull. Ran great with the eco on and off. Plugged in some test devices. It shut off after about an hr. Checked the oil- good. Checked the gas- good. Made sure the gas was turned on, I'm old, I forget lol. Started right up. Would run 15 min - 2 hrs and shut off. Contacted Amazon for product support. They referred me to the manufacturer after some stupid unrelated questions from their customer service. Contacted the manufacturer. Waiting........... I will update when or if anyone gets back to me. Right now I suggest you not buy a generator from Amazon. They don't care. Update: Still no response from manufacturer. I have not been able to talk to a live person, only leave messages. Update: It's been 4 days I didn't hear from the manufacturer. Called Amazon again 1st person transferred me, 2nd hung up after telling me nothing they could do. I called back, transferred. I was given a different number for the manufacturer. I finally got a real person. They are going to send me a new CO sensor. Nothing as of today. I guess I'm on my own. Received nothing. 3/26/2024 I suggest no one buy a generator from Amazon. They don't allow returns on any generator. You have a 50/50 chance of getting a generator that works. I can't afford them odds. I'm still able to charge my batteries, sometimes for 10 minutes sometimes I get an hr+. That's unacceptable. Will not run! This has been a piece of sh*t since day 1.
