Features

  • ULTRA-POWERFUL 4800W SURGE OUTPUT Powered by a heavy-duty 223cc 4-stroke OHV engine, the PowerSmart inverter generator delivers 4800 peak watts and 3800 rated watts. Unlike standard 4500W models, our extra 500W headroom ensures high-induction appliances like 15,000 BTU RV air conditioners and sump pumps start without overloading.
  • ONE-TOUCH ELECTRIC START & CO ALARM Skip the strenuous pull-starts with our reliable Electric Start system (Manual backup included). The integrated CO Watchdog sensor automatically shuts down the generator if dangerous carbon monoxide levels are detected, providing essential protection for your family during emergency home backup.
  • 10-HOUR EXTENDED RUN TIME Equipped with a 3.43-gallon large fuel tank, this gas powered generator runs for up to 10 hours at 50% load. The intelligent Eco-Mode adjusts engine speed in real-time to match power demand, maximizing fuel efficiency while maintaining a whisper-quiet 65 dBA noise level at 23 feet.
  • CLEAN POWER FOR SENSITIVE DEVICES Advanced inverter technology produces pure sine wave electricity with low THD, making it safe for laptops, phones, and medical equipment. Features a rich power panel: 1x 120V 30A RV-ready outlet, 2x 120V household outlets, 12V DC outlet, and dual 5V USB ports.
  • PORTABLE DESIGN & LIFETIME SUPPORT Weighing 89 lbs with a compact frame, this small generator is built for mobility on job sites or campgrounds. Includes a tool kit and oil funnel for quick setup. We provide professional technical support to ensure your power never cuts out when you need it most. Two-year warranty.

I’m very impressed with this PowerSmart generator so far. It arrived well-packaged and looks solid and well-built right out of the box. The design is compact and sleek, making it easy to move and store without taking up too much space. The instructions are clear and straightforward, and it powered on without any issues. It runs relatively quietly compared to traditional generators, which is a huge plus, especially if you plan to use it at night or in residential areas. The control panel is clearly labeled, and the outlets feel sturdy and secure. I also appreciate the fuel efficiency and the overall quality for the price. It feels reliable and dependable, whether for emergencies, outdoor use, or backup power. Overall, this generator exceeded my expectations and seems like a great value. Highly recommend for anyone looking for a portable, user-friendly generator 👍 ... show more

    • It's There when You Need It!
I bought this generator anticipating bad weather with power outages. We've had the bad weather, but so far, no power outage. The generator is easy to move because of the handle and wheels. It starts easily and I love the pushbutton starter! Just be sure to attach the battery cable located inside the oil maintenance cover, or the button won't work. The instruction manual is very detailed and covers every aspect of the generator design and function. Since I haven't really used it yet, I can't comment on the power it produces or fuel efficiency. But based on my experience so far, and other reviews, I expect to be pleased with its performance. ... show more

    • Defective right out of box!!
Purchased this generator took it out of the box started right up but had no display nor did it generate any power from receptacles. Contacted Amazon sent them videos and they told me I’m responsible for shipping costs to ship it back!! Buy from your local big box stores where you can return for free if defective!! Would’ve given 0 stars if I could’ve. ... show more
