Best for Quiet and Longevity
Honda EU2200i
- Starting / running watts: 2,200 / 1,800 W
- Weight: 47.4 lb
- Noise at 25% load: about 48 dBA
- Runtime at 25% load: 8.5 hr on 0.95 gal
Bottom Line : The quieter, smoother, longer-lived of the two.
Pros
- About 48 dBA at a quarter load
- Smoother and quieter under heavy load
- Starts first pull after months in storage
- Two in parallel ran a 30 amp RV panel
Cons
- No RV outlet: needs an adapter
- Premium price
Under medium and heavy loads the Honda was clearly the quieter of the two, with much better engine vibration damping. John's older Honda is on year 8 with zero issues.

Head-to-Head Results
Scores out of 10 are from our best inverter generators guide, where both rank in the top ten.
Quietness
Where we tested it. Side by side on the trip, at a quarter load and under medium to heavy loads.
What separated them. At a quarter load the Honda read about 48 dBA and the Champion about 53. Under medium to heavy loads the gap grew: the Honda was clearly quieter, and its engine vibration damping was much better.
What it felt like. The Champion's note is raspier and easy enough to tune out; the Honda you mostly forget is running.
Portability & Weight
Where we tested it. Carried in and out of camp.
What separated them. The Champion is lighter, at 39.7 lb against the Honda's 47.4. Both are one-person carries; the Champion is the one you take down a steep trail with a cooler in the other hand.
What it felt like. The 8 lb difference shows on long carries, not on the walk from the truck.
Runtime & Efficiency
Where we tested it. Hours per tank at a quarter load.
What separated them. The Champion ran 11.5 hours on 1.1 gallons, the Honda 8.5 on 0.95. Per gallon they are close; the Champion carries a little more fuel.
What it felt like. Either one lasts an evening and a night of light camp loads.
Power & Capability
Where we tested it. Camp loads and motor starts.
What separated them. The Champion has the bigger starting surge, 2,500 W against 2,200, though owners report it still trips on a 13,500 BTU AC without a soft starter. The Honda ran a 15,000 BTU AC with a soft starter, and two in parallel ran a 30 amp RV panel.
What it felt like. For tools and short surges the Champion has the edge; for long, heavy running, the Honda is the calmer machine.

Honda EU2200i vs Champion 2500-Watt Ultralight FAQ
Is the Honda EU2200i worth the extra money over the Champion 2500?
If you run it often or near other campers, yes: it was clearly quieter under load and far smoother in our side-by-side. For occasional use, the Champion gives you more surge and less weight for less than half the money.
Which is lighter, the Honda EU2200i or the Champion 2500 Ultralight?
The Champion, at 39.7 lb against the Honda's 47.4 lb.
Can the Champion 2500 Ultralight run an RV air conditioner?
Not on its own: owners report it trips on a 13,500 BTU AC without a soft-start kit. Fit a soft starter, or pair two units with Champion's parallel kit.
