    • My new favorite Generator (Updated)
Review Image by Dan the battery man 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

    • Fired right up.
Fired up on the second pull. Tested with meter and all outlets worked. Did 5 hour break in. Powered my rig just fine. Was able to run 2 air conditioners with no problem. One has soft start the other does not. With some power management it also ran my electric fireplace and electric water heater. Did another 5 hours and changed the oil again. More power, less weight, and smaller size than my old 3200 that weighed in at 80lbs. If there were two things that would improve this: make it a little quieter under load and put counter on it so you know how many hours it has run. ... show more

    • Quiet, easy to start and maintain.
Very well made and a lot of thought was put into sound attenuation and ease of maintenance and servicing. Starts easy and fast and operates well.

Im sitting here actually laughing writing this review. I’ve been wrenching on cars for 28 years, and was a small engine mechanic before that. I remember when these guys came out, and I’m a brand name b*****d. As we all know, quality in a product nowadays is NOT what it was a decade or more ago especially from familiar names. This thing really is an engineering marvel. I know my stuff, do my research repetitively, and I’m humored that this company crammed a 149cc engine in this with a considerable punch, while making an a$$ out of the biggest brands in portable power. The unit I looked at was 3300 starting watts, no fuel shut off, no gauge for the fuel, 10 pounds heavier, only 2500 watts running and bigger. And significantly more expensive. 799 that is, plus not having a good rap for customer service. This one boasts considerably more power, a fuel gauge, lighter, longer run time, better build quality and I can keep going. It’s exciting to see. Do your research, this company really has something when it comes to build quality, ease of use, maintenance, and very clear instructions along with 24 hour customer support. Good luck finding anyone that offers that nowadays. In a world that quality and service is not what it used to be, I suggest you look very closely at this company, you won’t regret it. ... show more

    • Nice Generator for Camper
This is a great RV generator; it's light (68 lbs) and quiet (think of the level of quietness of a vacuum). We love this generator. Starts easy also. 3500w - runs our a/c in the camper all day without a problem.

    • A quiet beast
My second bite at the apple with a champion generator. Wasn't that happy with the first one that is duel fuel and 4500/4000 watts but I have used my new portable champion generator 2x now and I love the ease of the pull start and how quiet it is. This is my new go to. I ran it for 4hrs with not a moderate load and I only went through maybe half a tank. Do with it would tell me my load use ... show more

    • Good purchase.
Easy start and light weight. Very quiet at idle but does get a little louder at full draw which is expected and still within reasonable levels.

    • Excellent quality small generator completely works as advertised.
So far so good. Starts on first pull runs smooth, steady power and pretty steady on the RPMs too. I used it for eight hours a few days ago when we had a planned power outage. I put it through its paces I plugged in four devices at once. But when I plug in a small ceramic heater that pretty much absorb all the amperage available. I do wish I had gotten a 6500 W version. But I bought this basically for emergencies and mostly just to keep my food and meats good in my refrigerator and upright freezer. I also found out in that eight hour period I did burn about 2 1/2 hours of gas, pretty much as advertised. It ran smooth the whole time it’s a very good quality little generator. Definitely worth the price of under $600 that I paid. I have to give it a 10 out of 10, I have no complaints except I wished I had gotten 6500 Watts. 🥹 ... show more
