Rated 4.0 out of 5 by 25 reviewers.
Rated 5.0 out of 5.0 by Great Value for the price I bought this for use on camping/hunting trips after getting rid of another generator that provided too much variance in voltage output. Wanted a high-end inverter-generator that put out a steady current without paying high-end prices. This one fit the bill and my pocketbook. Starts on the first pull, runs great, powers a refrigerator, vacuum sealer and 12-volt battery charger all at the same time, consumes less than a gallon of fuel in six plus hours and is whisper-quiet. I couldn't be happier with this product. April 10, 2012
Rated 5.0 out of 5.0 by This generator is all it's advertised as. The first thing that caught my eye was this generator is powered by a Yamaha engine. From previous research, I knew Yamaha generators were rated #2 on noise and #1 on durability. The second thing was the price. At least $300 less than a Honda or Yamaha. I took it out of the shipping box, filled it with gas and oil (Don't just blindly dump the whole container supplied in the crankcase as it will overflow and make a big mess), read the quick start instructions and started it up. From the first try to every subsequent try, it was 1 pull to start. I have taken it camping with me on 3 seperate occasions now and I couldn't be happier. I used to own a motor home with an Onan Generator that brought noise complaints from my neighbor campers every tme I fired it up. All I get when I fire this one up is compliments. I really like the fuel pet cock valve that allows you to shut off the flow of fuel so the generator starves itself to a stop. This eliminates any fuel from collecting in the fuel line or carburetor between uses. May 14, 2013
Rated 5.0 out of 5.0 by Product works as advertized This is equal to the Yahama generator that sells for $300 more. All the same features and very quiet. Starts on the first pull and handles 1600 watts of devices. Better features than the Honda, especially fuel shutoff for storage. Put out 19 volts trying to charge a dead battery. Excellent. Smarter Tools tech group very knowledgable and helpful prior to purchase. HD should put these on their shelves. Mine was delivered within 5 days with no shipping charges. Will bring to the boat soon to charge batteries, make coffee, run the microwave, heat 6 gallon HWH and maybe run the 1/2 ton AC unit (doubtful) in aft berth. Will see how it does in the salt water environment of FL September 22, 2012
Rated 5.0 out of 5.0 by works nicely with UPS backups, keeps office/server equipment running smoothly, & purrs like a cat! This generator works perfectly with a variety of UPS backups. I tested it with both my cheaper TrippLite Omni900 UPS, and with my more expensive APC SmartUPS 1500RM UPS, and contrary to what one person ("mvrm") had written about ECO mode on his APC 1000 & 1500 UPS, neither of mine had any problems. My guess is that he had not seen the "sensitivity" switch on the back of some APC models, and inadvertently set it to "high sensitivity"... or he was trying to run a heavy load in ECO mode! I wanted to be absolutely sure that I could use ECO mode to extend the run time on my UPS during the hurricane season, so I ran several tests with loads ranging from 150W to 300W and the generator just purred quietly in ECO mode, with no issues on either UPS, and no issues on my TV, internet or computer equipment. Just as a point of reference, my TrippLite UPS has stepped sinewave with sluggish AVR response & no sensitivity switch, while my APC has smooth sinewave output with instant AVR response, set the defaults for "medium" sensitivity & 127V cut-off, and both worked without a hiccup. The APC reported 124.8V @60.25hz the whole time. So then I did even more tests, using a meter to watch the voltage while switching from ECO to regular mode & back, and still, it maintained a steady output of 124V despite the changes in speed. I also shut the generator off, then started it back up a couple minutes later, and I had no trouble starting it on the 2nd pull (1/4 choke), and I also confirmed that it is able to start with a small load (300W), so when the manual states to unplug the load before starting, they appear to be referring to heavier loads. In the end, I confirmed this generator will work very nicely in ECO mode, and should be able to power my equipment for 9 hours straight on a mere 1 gallon of gas... that's fantastic! By the way, I also took a very good look inside, and when they say "work smarter, not harder" they seriously know what they are talking about. The electronics have been dipped in epoxy to improve heat dissipation, the case is sealed like a computer to drive air-flow over sensitive parts, the engine is wrapped in heat shielding with a second case layer channeling air flow from the generator intake fan back around & over engine's cooling fins & over the exhaust to improve cooling, and the case is lined with rubber cushioning to deaden noise. At nearly half the price of a Honda, its a nice little generator & worth every penny! July 13, 2013
Rated 5.0 out of 5.0 by Filled with Oil, started right up. As Quiet as I had hoped. Brews Coffee from our 10 Amp Electric Perk. I had an Excel sheet with dimensions features displacement power etc. Smarter Tools came out on top for Noise (51db) Displacement (75cc) Max Power ~16 amps , Weight 44lbs and similar dimensions. It's price was positioned well between the well known Honda and Yamaha and the cheaper, louder versions. After I figured out that I had to pull fairly hard to get the side panel off everything went well. Oil fills very slowly but it was in and fill level seemed appropriate. Turn on gas valve, switches in recommended position, pull on choke and a couple of pulls and it started right up. We used it to brew some coffee and marveled for a few moments on how nice and quiet it is. April 16, 2013
Rated 5.0 out of 5.0 by first impression I got this as an inverter generator to use for portability and quietiness. It has the Yamaha engine rated for long life! smart control to slow down idle with steady load. The gas cap was broken on shipment; email to company and I had a new one in two days; no charge. runs nice and quite. Have not really loaded it at this stage. no official power outage to test it with yet. It has two 110 V outlets or one battery charging outlet . No twist lock plugs like some bigger generators have. About 44 lbs makes it easy to move. August 14, 2012
Rated 4.0 out of 5.0 by AS good As good as the Honda 2000, but $200+ cheaper. The rating is the same as Honda. As from as my RV, run's everything ,but the AC, so I would need 2. March 21, 2013
Rated 2.0 out of 5.0 by not as quiet as claimed I bought this unit mostly because of it's name brand engine and it's claim of 51 decibel sound level. First time I tried it the gas cap broke. They admitted there was a problem and sent me another. The unit is not as quiet as they claim. It is not as loud as a regular generator, but it is not as quiet as the name brand unit of the same size. The second time I used it the gas cap was broken again. When Hurricane Sandy hit I tried to use it again and the red overload light came on and I shut it down to reset the internal breaker( according to instructions). I was never able to get it to run properly after that. To their credit Home Depot allowed me to return it to the store even though I bought it online and it was a few days after the return period. I will definitely continue to shop with Home Depot, but I will spend the extra money and get the name brand generator. December 16, 2012
