    Purchased this unit at the Grisham OR store in September of 2014. Brought it home tested it (all OK), used during a power failure this winter worked fine. I got it out to go camping and it would not idle. Called Champion and was told it was a fuel problem, not covered by warranty. I would have to pay for all repairs, TWICE. I own many gas operated items and have never had a problem even my 50 year old Evenrude outboard still fires right up. All I can say is, don't buy this unit without an extended warranty from someone you trust because you will probably need it.
    Cons: Bad Instructions

    After a disastrous bout with a off brand, it wasn't a hard choice to come back to Champion. My main power plant is the 4000/3500 that has started and ran flawless at every temp from -40 to 95 degrees, using 10w30 synthetics, Altitudes from 5000 to 9800 feet above sea level. Needed a smaller unit to back our camping and emergencies. Again, chose Champion to take care of our needs. An as expected, this little unit 2000 watt inverter easy to set up 10w30, treated fuel, started first pull, love the eco mode, whisper quiet for our needs, full throttle is friendly. Powered up our camper with no signs of peaking wattage (lights, fridge, microwave batteries water pump). Don't expect it to run your 13-15000 btu cooler, it won't, so don't bother trying. Don't like how you need to change the oil, but I will get over it! Bottom line is, Champion just works. Very reliable and cost efficient. Camping World staff in the Idaho Falls area was great, I will be back to their store again! Happy RVing to all.
    Pros: Quiet, Easy to Use, Light Weight, Reliable

    Excellent quality generator

    I expected it to be cheaper quality but was pleasantly surprised. However there was a slight issue with the unit right out of the box...after I took the side cover off to add the oil to the engine I noticed that the inverter unit was crooked, it had fallen out of its mounts. Looked like it might have gotten jarred in shipping which could have caused the rubber feet on the inverter to pop out of the mounting slots. Anyway, it was an easy fix to loosen up the enclosure screws and place the inverter back into its place, screw it down and button everything back up. The controls and switches appear to be good quality and the unit overall seems to be well-engineered. The inside of the enclosure is well-insulated to provide maximum noise control. I also liked that included was an oil filler funnel, a spark plug wrench, a USB plug and a pair of battery charging cables included with the generator. After adding the oil (not included) it started right up and ran smoothly. Hooked it up to a couple of lights for a load and let it run for 30 minutes, all was well. I bought this for backup power for my home heating system and it should do nicely running my gas boiler and a couple of circulation pumps. Even in non-eco mode the unit is very quiet, in eco mode almost unnoticeable from 25 feet away. I would recommend this to others who, like me, feel like layout out a kilobuck for the Big Red brand of generator is way too much! I gave this unit 5 stars. The long term reliability is unknown at this time, so I'll revisit and update when I've used it for awhile.
    Pros: Quiet, Light Weight, Features, Price
    Cons: Lower quality

    Louder then expected

    Bought to replace the Yamaha 1000 we had. I went with Champion because I had very good luck with another champion for years. The non inverter type 4kw. It is 4 years old and still starts 1st pull every time so I purchased this hoping it would suit my needs and be just as reliable. Just as with my other champion it started 1st pull and ran clean and sharp. However, it was louder than I expected. We were looking for something very quite just to run a few lights and a TV in the trailer. I really do not want to hear a generator at night while watching TV or sleeping but this one I could certainly hear running but of course nothing like the 4KW unit we have. If I turn on more than a couple lights it would rev up pretty loud. It also would not run the microwave which was a disappointment because the only reason i moved up to a 2000 from the Yamaha 1000 we had was to run the microwave from time to time without starting the main generator. Overall it looks to be a good product and should be reliable it is just is too big ad too loud for my needs. And I do not think the rating is accurate since it would not run the microwave.
    Pros: Easy to Use, Price
    Cons: Loud, Just a little on the loud side sometimes

    Great generator

    I bought this generator a little over a week ago. I have a 36 ft travel trailer in a storage facility where there is no power to clean after trips. Since we live in central CA and summer days can be over 100, we wanted something that I could run the main air conditioner and a vacuum to clean. I originally looked at new Champion 3500 carried by Camping World but was not sure if it would run both. I emailed Champion and they recommended 2 of the 2000 watt inverters paralleled together. I have only purchased 1 so far and I am very pleased with it. It is light weight and far quieter that I expected. After following instructions it started right up. I had a chance to try it at trailer this last weekend and vacuumed using a Dyson canister vacuum. I am looking forward to getting the second one. Today is supposed to be our first over 100 degree day of the year. I highly recommend this to anyone looking for a light weight quiet generator.
    Pros: Quiet, Easy to Use, Light Weight, Exceeded Expectations

    Beware of high elevations

    Please don't make the same mistake I made. I currently own the 3,500W/4,000W Champion generator but was looking for a lighter/quieter generator that could power our microwave and charge the house battery on our travel trailer as a back up to the solar panels in case of cloudy weather. Based on all the positive reviews of the Champion 2000W Inverter and recent reviews/questions on multiple forums, I pulled the trigger. Upon the first camping trip at 9,000 feet at Big Lake, AZ, the first day was mostly sunny but turned to overcast the remainder of the trip. I started up the generator and let it warm up before I flipped the 20 amp breaker on to power the microwave and charge the house battery. The generator never made it to full rpm (out of Econ mode) with only the converter on. It only idled in Econ mode. I switched off the converter and turned on the microwave which overloaded the generator, even on the lowest power setting on the microwave with the converter breaker switched off. Giving up on the microwave I wanted to charge the house battery using the Progressive Dynamics converter. Upon flipping the converter breaker on, the generator strained and struggled, but could not rev up. Fortunately, the solar panels were enough to keep the house battery at 11.50 volts the rest of the trip during overcast skies. When I returned home back to 1,175 feet, I tried the microwave and battery converter which the it ran but not at the same time. I spoke to a Champion rep and was told that there was not a high altitude jet available and that for every 1,000 ft in elevation you lose 3% power. Too bad that's not listed under product specs or in the users manual. I ended up selling it for $400 and plan on buying the new Champion 3,400W inverter generator model. Bottom line, if you plan on using this above 5,000 feet, plan on buying another 2,000W inverter and parallel kit or buy the larger 3,100 or 3,400W inverter.
    Pros: Quiet, Easy to Use, Light Weight, High Quality
    Cons: Not for high elevations
