Champion dual-mode generator # 100155 $799

Hello!

Looking at Champion portable generator # 100155 dualfuel unit from Costco for $799. 7K run watts Gas 6k watts propane and 74 dba.
Hoping for informed opinions about this brand/model’s reliability and performance especially as it pertains to 30 Amp RVs. Would also serve power tools and back up power for some household items in power outage. It is large at 225 lbs which I prefer to think of as a Theft Deterrent;)?

Question: The sign at Costco states “Clean sine wave 5% THD”, although the Champion website makes no mention this model being an Inverter Generator. What does that “5% THD” mean relative to other units that are clearly marketed as “Inverter Generators?”

Thank you in advance!

  • I agree that generator is too large, both in output and weight. Since your profile is incomplete, we don't know what you're trying to power?

    Our Costco has the Champion 2800 watt running / 3100 watt peak inverter gas only generator for $699.99. It has a 30A RV outlet and will run a single 15,000 A/C. The weight is less than 99# and they can be daisy chained together.

    I'm looking at one of these since my Honda 2000s won't run my single 13.5 A/C

    In looking at the generator you mentioned, I really don't see any advantage of the dual fuel option and using propane. It states it will only go 5.5 hrs on a 20# tank at a 50% load. If you run it at full load, it may only get 4 hrs on a 20# tank. You may need to only stay at campgrounds that sell propane.

    In reading one of the Costco reviews the writer who used it during a five day power outage was disappointed in the propane consumption and said this about the noise: "It's loud, like seriously loud, even in the house... at the other end of the house". In looking at the pictures, it is not an inverter generator.

    You mentioned it produces <5% THD for clean power. The smaller generator I listed above does <3% THD.

    If you have two 15,000 A/Cs you do need a larger generator, but the one you're looking at doesn't have a 50A outlet, only 30A outlets. I'm assuming you saw that and will assume you don't have two A/Cs? If that's true, the smaller generator will run your A/C. weigh less, cost less and use less fuel.

  • To clarify for the OP, this is NOT an inverter generator. It is simply an alternator powered by a gas engine. This simple design makes them very reliable, and Champion has the best reputation for reliability out there.

    As said, champion also makes inverter gennies, and they are highly thought of. But none that come anywhere near this size.

    Again, I would get two smaller gennies. This giant gennie is tough even to wheel around.
  • I have used this gennie for home backup, a task for which it is ideal, IMO. This gennie weighs 250 lbs, IIRC, and it was a struggle for two men to lift the crate down out of the back of a truck. Is this the kind of camping gennie the OP desires? I would get a smaller gennie--or two of them.

    It is louder than the champ 3500/4000, but the tone has none of the "clanginess" of the smaller gennie, and is actually much easier on the ears. While I ran it briefly on gas, I ran it for the better part of a day on several occasions on LP, and its performance on LP has opened my eyes to the potential of LP gennies.

    While it is a rotational generator, there is so much rotational mass that heavy startup loads do not affect it one bit. I stood next to it with TWO 1500 watt heaters and flipped them on and off in unison and neither the voltage nor the frequency did more than flicker briefly.

    The sine wave of these rotational generators is very good, owing to the rotational nature of the wave creation. I haven't scoped it, but we did use it on sensitive electronics (giant TV, reciever, cable box, DVD plaer, etc) and nothing complained one bit.

    I would HIGHLY recommend this gennie for home backup, and I am confident the OP will come to his senses regarding camping use once he sees this giant hunk of iron in person. It is way too big for transport, and yes there are quieter gennies out there.
  • I recently purchased the Champion 3500 watt inverter generator. It handles 15k AC and other small electric items in RV with no problems. It is very very quiet. Recently neighbor and I standing within 4 ft and having a normal conversation. Longest run time I have had is about 6.5 hours with AC and lights, TV and small fan running in RV during low 90's temps. I known CW has them on sale now for $1099. Might also check Cabela's or Lowes as they offered them online with free ship to store. I am probably near 100 hours use and very happy with purchase. Also has electric start.
  • From Champion site

    6300 Watts running propane

    74 dba @23 feet

    EDIT: And the same also from Costco site
  • That generator, and all like it, are not suitable for camping unless you are completely alone. It's way too loud.
