    • Best Value in a mid-range Inverter Generator
Color: red
This generator is a great deal. Small size and runs on propane or gasoline. I was able to get it set up and running very quickly. I have not run it on gas yet, but it runs great on propane, which I prefer to keep.the carburetor clean and minimize maintenance. It has a slightly lower power rating while running on propane, but that is true with any dual fuel generator. It runs much quieter than I expected. Once it has run initially, it has started on a single pull of the chord. So far I've used it to test output and under load it does very well. When running a small load such as amateur radios and two operate battery chargers, it is very efficient. The power output is very clean as well with almost no variation in voltage or amperage. I would recommend this generator to anyone looking for a good value and for reliable starting and operating. It is light enough to haul around when needed and quiet enough for outdoor needs where it can run without being annoyingly loud like my other generator tens to be. Just get one! ... show more

This is my very first generator I’ve ever owned. For me it’s a little bit heavy but when I watch videos, those guys just pick it up like it’s nothing. I bought a cart for it and a cover. When it’s a yucky day out and my solar isn’t working this thing does fantastic. I’m also running my portable air conditioner with it just to try to beat some of the Consumers Energy costs. I like it. It’s easy to use and it is pretty quiet. ... show more

    • A lot of bang for the buck.
Color: red
After extensive research I bought this generator for emergency use because of its price point and many features. Unfortunately, we got hit by a tornado last week and my generator decided NOPE, I'm not going to co-operate. This arrived in three days and setting it up was pretty straight forward. Added oil and I decided to use gas for the initial break-in. Two pulls on the rope and we were off and running. I plugged in two things that I thought were essential, the refrigerator and an electric fireplace. The refrigerator had little effect, but it really kicked in when I turned on the fireplace. I checked the display and I was only drawing 1475 watts, so I still had plenty of power for a couple of lamps, the internet, the computer and maybe the TV. With only half a tank of fuel I unplugged everything and let it run with eco mode off. Three hours and forty-five minutes later it ran out of fuel so I could do an oil change. My initial thoughts and some drawbacks. * The machine is heavy. Specifications say it weighs 50 lbs. It feels heavier although I don't have a scale to confirm my suspicions. Shouldn't be a problem moving it around, but I sure wouldn't carry it down the street. * Access panels on both sides and the oil change door require a Phillips screwdriver. * It gets loud. Eco mode is fine but as the load increases, so does the noise, but that can be said of most generators. * Small gas tank at only 1.3 gal. If you need to run it all night better use propane otherwise, you'll be getting up early. * The display. Although it's explained in the manual it doesn't go into great detail. You have to use it to finally understand it. If the generator is on the ground, you have to get on your knees to read it. Bluetooth would be a great option here. That being said, I am very happy with this generator. For the price (I bought it on sale), but even at full price, it stands out from other more expensive generators. It has more than enough power to run the essentials, an RV plug, a display that actually tells you how it's performing, and the ability to run on gas or propane. I would definitely recommend this generator. ... show more

    • Generator that handles real household loads
Color: Red
I’m very satisfied with this generator. I bought it mainly for backup power and for occasional outdoor use, and so far it has performed better than expected. It starts easily, runs smoothly, and the noise level is noticeably lower compared to other generators I’ve owned. The build quality feels solid, and the setup was straightforward even for someone who isn’t a mechanic. I tested it during a short outage with several appliances running at the same time. I plugged in my refrigerator which draws around 150W while running, a 700W coffee maker, a box fan at about 50W, and some LED lights that used around 20W. All together the load was well within the 2500W capacity, and the generator handled everything without any power drops or hesitation. My only complaint is that the fuel tank feels a bit small for longer use. It works great, but if you plan to run it for many hours, you will need to refill more often than with larger models. Overall, this generator has proven strong, quiet, and dependable for real day to day situations. Even with the small downside, I would still buy it again with no hesitation. ... show more

    • Amazing generator for the price.

Blown away for the price point. Pulled it out of the box, added oil, hooked to propane, and started on third pull. Ran it for 30 minutes hooked to my RV running my 8000watt A/C AND my 110v mini fridge/ lights etc. no issues whatsoever. You could definitely hear it spike when AC kicked on, but handled it well and ran impressively smooth and quiet. Will be perfect for tailgating, weekend camping, or as a backup when we lose power at the house. Would definitely buy another. Very happy so far. ... show more

    • Good generator
Color: red
I love my Powersmart generator. I am a 61 year old woman who has had heath issues, but I am able to load this generator into my pickup bed without any help. I use it exclusively with propane, because filling it with gas makes it too heavy for me to lift. I had to figure out the trick to getting it to start on propane, which is to make sure there is no air in the propane line by releasing a bit of propane before hooking it to the generator, and then very slowly opening the propane valve. Once I got that figured out, I’ve had no trouble at all with this generator. However, I did have to get a new oil plug for it because the first one was screwed on incorrectly, and the threads were stripped out. ... show more

    • Reliable Power When You Need It Most!
Color: Red
I purchased the PowerSmart 2500 Watt generator and couldn’t be happier. From the moment it arrived, setup was straightforward and easy to get it up and running. It’s compact yet powerful, perfect for home backup, camping, or powering tools in remote locations. The generator runs smoothly and quietly, and I was impressed by fuel efficiently. The build quality feels solid, and it started up effortlessly right out of the box. I’ve already used it during a brief power outage and it kept my essentials running without a hitch. Plus, the price point is unbeatable for the performance it delivers. Highly recommend this generator to anyone looking for dependable, portable power. Great value, great product! ... show more

    • Impressed
Color: red
Genuinely impressed. Bought to ensure we had power in an outage, even though not often. Added oil, hooked up to propane and ran a fridge, a medium chest freezer, lights, TV - to be safe, I unplugged the freezer while I ran a large toaster oven combo and separately, a Keurig. Thought I'd run out of propane based on reviews at the 4 hour mark (not eco) and swapped tanks. The new tank ran for 9 hours and still had propane left. Ran the first tank for another 4 hours for a total run time of 21 hours. Had backup gas and never needed it. Only annoyance is the screw holding the panel on the oil. Screwdriver didn't work and had to find a socket to loosen it. ... show more
