    • Excellent Portable Generator

Review Image by johnathon clarke
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

    • Very Impressed
Set name: 4800 Watts CO Protect
Very Impressed. From the owner of two Harbor Freight Predators and a Honda EU. This unit exceeds my expectations for a Honda clone inverter. I was in the need for a mid sized higher output unit for my truck camper to carry on my front aluminum rack and this thing is perfect. I have ran in so far to break in and check voltage and test how it works with my camper. My Honda 2000 was too small and my Predator 9500 too large I figured give this one a go and it is working out well run in a/c, fridge, and batt chargers on my Travel Lite while fishing. WARNING!!! Be aware same as any Honda clone from over seas do several oil changes for break in period during the first few hours of operation. My first couple of oil changes came back very metallic and shiny. This gets all the manufacturing shavings ect. Out of the crankcase to extend the life of the engine. DO NOT just fill with oil and run to 50-100hrs this will significantly reduce the engines life with pre-mature wear! Also get rid of the Chinese spark plug for a BPR6ES it starts one pull every time. ... show more

Set name: 4800 Watts CO Protect
Have been able to run a few tools on it with no issues. All you need to do is add gas and oil. It is easy to move due to having wheels. Easy to use and compact. Highly recommend!!

    • It's There when You Need It!
Set name: 4800 Watts Electric Start & CO Protect
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

    • Good generator, bad battery!
Runs great, very quiet other than the wheels rattling. Battery for the auto start died after the first use.

    • Very bad Generator. Dont ever buy this.
Set name: 4800 Watts CO Protect
Hey all......Matthew from Santa Paula, Ca. I bought this gernerater about 5 months ago, and I never took it out of the box till just recently, and when I did i put in gas, & oil, and tried to start it. It would not fire up. I followed all the directions to get it working, nothing. So I contacted the seller and they were having me jump through hoops to get this started. I was not going to do all that. I took the product right out of the box and it should work. Nope. So I reqested to return it, with a full refund of $ 800.00 and some. So I am having Amazon to step in. Then the seller offered me 50% of the total price just to move on and shut me up. Nope. Unexceptable. So bottom line never ever deal with a 3rd party seller it is the worst. And never buy this product. Oh I did order it with electric start never came with it. I am a Amazon loyal customer. ... show more
