    • A Must-Have for Outdoor Adventures and Backup Power!
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! ... show more

    • No support from Amazon or Manufacturer
Style: GM1200i
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. ... show more
