    • Delivers just as advertised and very quiet, but don't expect more than 2000 watts at 5000 feet
Style: 3300-Watt Inverter - COsense - 49 ST
This Generac 3200i (2500-continuous watts) should do the trick the next time power goes out at our home. I wanted to buy a Honda EU2200i because of its quietness and reputation, but at 5500 feet altitude I didn't think its 1800 continuous watts was up to running the gas furnace, the fridge, and a few lights and battery chargers. The Generac was $500 cheaper and nearly 40 percent more powerful. Out of the box, I had to run at half choke for nearly a minute before it started to run normally. Otherwise, subsequent starting is a breeze. It's wonderfully quiet as well; it definitely won't bother us or the neighbors. And I'm glad I got the bigger wattage. I tested it with several combinations of current draw. It will run two circular saws simultaneously, but the engine bogs way down and my in-line watt meter indicated supply reductions of several hundred watts. That's not a problem for making a single cut but it would definitely be bad for the motors long-term. It powers either circular saw or a 1500-watt milk house heater just fine, but add any two in combination and it bogs down and doesn't recover. The best it could do was to run a milkhouse heater on the low setting (1320 watts draw) and a 6-amp drill (630-watt draw) for a total draw of 1950 watts. That's about right, given a 4 percent reduction in engine output per 1000 feet above sea level. The Generac 3500XL I bought 35 years ago ran great until the plastic gas lines rotted out. I could have repaired the gas lines but I worried about how clean the power would be for electronics these days. This new 3300i isn't pure-sine-wave output, but at 3 percent THD, it's close enough. Thus far, it delivers exactly as advertised. My only wish is that it came with the switch to turn the eco mode off. That might help with starting in colder weather. Maybe that won't be a problem, but I won't know until our first winter comes along. ... show more

    • Power up
Style: 3300-Watt Inverter - COsense - 49 ST
Just purchased. Set up was fairly easy, although you have to remove the side cover to access the oil fill tube. Not a big deal, only 4 screws involved. I filled with ethanol-free gasoline. The choke dial is easy to use. It started fairly easily - second pull on first start. Subsequent starts required just one pull. The generator is very quiet and fairly portable for a 60 pound box. I have not had to use it yet for a power outage, but I feel confident that it will deliver good performance. ... show more

Style: 2500-Watt Inverter - COsense - 49 ST
Living in remote Alaska, a generator is a necessity. We chose this generator due to its well known name. Worked great at first using a few hours daily. Fast forward 3 months....3 MONTHS....no notice, no start! Closest "authorized dealer/repair" 4 hours away!! And no guarantee the repair will be covered by warranty. This is NOT what I would expect from this brand!! Honda will be our next stop!! ... show more

Amazing generator! When I say quiet, I mean QUIET! We use it in conjunction with our solar system to power up our off grid homestead. Our last generator could be heard a mile away!

    • Quiet
Style: 3300-Watt Inverter - COsense - 49 ST
I have a whole house generator by Generac, that comes on automatically when the power goes out. I’ve been very satisfied with its performance. Had it two years now. So when I went looking for a generator for my RV, I looked at everything out there. And decided on this Generac. I must say I’m thoroughly impressed with this small generator. When they say quiet, they really mean it, I’m very impressed. In fact, the air conditioner is louder, much louder. I highly recommend this product. ... show more

    • Just as quiet as the competition
Style: 3300-Watt Inverter - COsense - 49 ST
After adding oil and gas, it took one and a half pulls to start this generator. I was absolutely in shock at how quiet it is. I then started to test the generator. I plugging in a portable air conditioner, a grinder and a 3 amp battery charger. No problem. I then took the generator to my boat and plugged it into the shore power for my AC. It ran my AC with no problem. I will plug in my battery charger for my electric outboard. ... show more
