    • The best all around generator for the price.
Output wattage: 3800 Set name: 4800W-CO Sensor
Straight out of the box it started up. One easy pull. The wheels and handle makes it easy to move. It’s nice and quiet and will be perfect for power outages and to take camping.

Output wattage: 3800 Set name: 4800W
I've owned several generators over the years, but the PowerSmart 4800-watt stands out as the best by far. I picked it up shortly after moving to Florida, knowing I’d need a reliable backup for household essentials during power outages. Right out of the box, it was ready to go — no assembly required. After adding oil and gas, it started with just a few pulls of the cord and ran much quieter than any generator I’ve had before. I placed it about 10 feet from the house, and with the door closed, I couldn’t hear it inside at all. Just three weeks after the purchase, a nasty tropical storm knocked out our power. Thankfully, I had also bought two 75-foot, 12-gauge extension cords and two 50-foot, 10-gauge cords — each with three outlets, giving me 12 outlets total. I ran the cords through the house and plugged in three standing fans, three lamps, a full-size Samsung refrigerator, a Primo water cooler, a TV, a modem, a portable air conditioner, and my laptop. With everything running, the generator used a third of its available wattage. We also interchanged a stand-alone 2-burner electric range for boiling water, a Gourmia toaster oven/air fryer, and a coffee maker when needed. The generator ran continuously for over 24 hours, powering all 12 sockets without any issues. The PowerSmart 4800 is solidly built, easy to operate, and it delivered reliable electricity when we needed it most. If you're looking for a dependable generator to keep your essentials running during a blackout, this is it. ... show more

    • Re Power SM generator.
Output wattage: 3800 Set name: 4800W-CO Sensor
Great unit!! Live in remote area with no public utilities, so this is sole source of power. Handles varying loads (lights, TV, A/C) perfectly. Quiet, easy to start - even a woman can start it easily. Would buy again.

    • Generator
It works well and is nice and quiet. This was important as I use it camping. I wish the fuel capacity was bigger as is does not quite last the night when running the heater and other appliances.

I am general contractor, we need the power generator for a project that has no electricity. The crew said can't go wrong with a Honda Brand, however the price is $2000ish for the similar features and load. There are many generators available from AMZN, I narrowed to 7 different brands, my final 2 were this and the Champion Brand, I picked this over the Champion due to it is slightly more efficiency and the look. This unit runs very smooth, and pretty quiet. Especially with its ECO mode, one tank of gas can last for few days. The down side for me is that the unit is about 70lbs, which is fine, however with oil and fuel it has over 100lbs. So for me to upload and unload from my work truck is a bite challenge. Otherwise, this is a outstanding generator. I am happy with the purchase. ... show more

    • A great generator for camping
Output wattage: 3800 Set name: 4800W
My power smart 4800 W startup inverter generator has been very dependable, the only thing I wish I would have gotten would have been a remote start but other than that it powers my entire 26 ft motorhome with no issue, we use it for boondocking.
