    • Great quiet inverter generator with lots of power
This is an excellent value generator. I've bought lots of generators and this is my favorite. Small and light but lots of power and the 30 amp RV plug makes it a top choice. Highly recommend!

    • Great buy. Happy with purchase.
Very happy with this generator. Used it for a home renovation where there was no power and it worked wonderfully. Easy to operate. Long lasting power with each tank of gas. Starts up easily. Lightweight. Relatively quiet.

    • My new favorite Generator (Updated)
Review Image by Dan the battery man
Update: I now have 55 hours on this generator and I am beyond impressed. I fabricated a generator mount for the front of my trailer, (See Picture), so I can run the generator while we are going down the road. (Keeps the inside of the trailer nice and cool)- and, yes, I have straps to hold it down when traveling (not shown in photo) I took it on a 3 day dry camping family vacation when the weather was very hot in August. Our Winnebago Voyage travel trailer has 2) 15,000 BTU Dometic rooftop AC’s and we had to have one of them on at all times. The Champion had no problem running one Air Conditioner at a time along with lights, and our large 12-volt RV fridge. It could not run the AC and the microwave oven at the same time. I really like the overload feature: if the generator goes into overload, it keeps running and a red light comes on the control panel, all you have to do to reset it is press the red button and it will start generating again (easy!) I have no concerns about running it all night under load until it runs out of gas, it does not damage the generator and it starts right back up after refilling. I disabled the CO detector (Thanks YouTube!!!!) it was easy and the generator has no issues with a hyperactive CO detector. On our trip running 24/7, It went through about 5 gallons every 24 hours, (the AC’s ran all day and most of the night) It didn’t burn any oil, started easily and was very quiet. I am more impressed with the quality of this generator every time I use it. So far no negatives, this is a quality generator especially for the price. Here is my original review: I have run it through its paces and it came out with flying colors! What I love about this generator: 1. It came really well packaged - no damage 2. It came with oil and a funnel 3. The door to check/add the oil has quarter-turn fasteners (no tools required) 4. Starts easy…I mean really easy ! 5. It is very quiet 6. Very light weight (47 pounds) 7. Very powerful - 4000 watts What I don’t like: 1. So far..nothing…. I did a 7 hour break-in and ran my 27 ft travel trailer with it. It started the 15,000 BTU Air conditioner with no problems. I ran the AC for 7 hours on one tank of fuel (the blower ran all 7 hours..the AC compressor ran for two hours) After the break-in period, the oil was pretty dark (not black, just grey) I changed the oil and put in Full Synthetic 10-30 oil. The oil change is easy if you buy one of those oil change suction devices. The controls are easy to understand, it seems like a very quality generator. I expect it to last many, many years. ... show more

    • Champion Power 4000 watts, an excellent investment
I bought this 4000-watt Champion Power power plant to send it to Cuba, that's why I don't have photos of the product with me. Even so, I wanted to share my experience because it has been an excellent purchase. The plant has proven to be powerful, reliable and very economical with fuel. In my case, with approximately 6 liters of gasoline and using it about 4 or 5 hours a day, connecting only the essentials, it can perform up to several days. It has been of great help during blackouts and fulfills its function very well. I am very satisfied with the quality, performance and low fuel consumption. I totally recommend it. ... show more

    • Would recommend especially for price and durability.
No worse than any other. Turning exhaust away from campsite really helps.

    • Highly recommend!
We purchased this generator for our camper for when we boondock. We used it many times last year and it worked perfectly. It’s definitely much quieter than other generators we’ve heard. It’s very easy to start. This was a great value for the size and money. Highly recommend!

    • Amazon Customer Service came through!
Review Image by Oddthing
When I received my first generator I noticed a small defect in the case enclosure. Having read the instructions, as always, it was recommended to put oil and gas in the unit and run it for a break-in period. While running it and connected it to our travel trailer, I noticed a small defect in the case (see picture below) that would allow water, dust, bugs into the generator. I could have easily fixed this with black caulk & duct tape, but after spending nearly $600 on this unit I didn't feel like fixing their QA defect myself. Fast forward 72 hours: I called Champion Customer service and since I put oil/gas in the unit, per instructions, I could not return this. They suggested I notify Amazon Customer Service, and after speaking with a very nice agent I was told I could keep the unit and get a full refund, or they will ship a new unit out, no charge, and I could keep both! I received my new unit within 48 hours The generator works perfectly and fulfills all our needs. Would recommend this unit. ... show more
