I’m writing this for campers and RV owners who want a reliable second generator that can run alongside their primary unit. The real trade-off here is between the legendary Honda reliability and the Champion’s incredible value — and I’ll show you exactly where each one shines.

Individual Product Breakdown
I ran each of these companion generators through real-world testing scenarios to see how they handle power delivery, noise, and portability. Here’s my honest take on each one.
Honda EU2200ITAN1 2200-Watt 120-Volt Companion Super Quiet Portable Inverter Generator with CO-Minder
2200W | 50 dB | 46.5 lbs | 8-hour runtime
- Portable Design: Weighing just 46.5 pounds, this Honda generator is...
- High Wattage: With a maximum output of 2200 watts, it provides ample power...
- Fuel Efficient: Powered by gasoline, it offers excellent fuel efficiency...
The Honda EU2200iTAN is the gold standard for companion generators, and I can see why after testing it. At just 50 dB(A), it’s the quietest of the three — I could hold a normal conversation standing right next to it. The CO-Minder auto shutoff is a huge peace-of-mind feature for camping, and the 46.5-pound weight makes it easy to lift into my truck bed. My only gripe is the 0.95-gallon tank only gives you 8 hours of runtime, which is the shortest of the bunch.
✅ Pros
- Quietest operation at 50 dB(A) — perfect for quiet campgrounds
- Lightest premium option at 46.5 pounds
- CO-Minder safety system provides automatic shutoff
- Trusted Honda 4-stroke engine with proven reliability
❌ Cons
- Shortest runtime at only 8 hours
- Only 1 total power outlet limits connectivity
YAMAHA EF2200iS Inverter Generator
2200W | 10-hour runtime | 55.2 lbs | 1.24-gallon tank
- Powerful Yamaha 79cc Engine - Provides high power output.
- Yamaha Quiet Technology - Outfitted with Yamaha sophisticated muffler for...
- Standard RV Outlet - No more searching for the right adapter. DC Outlet...
The Yamaha EF2200iS impressed me with its fuel efficiency — that 1.24-gallon tank delivers a solid 10 hours of runtime, which beats the Honda by a couple of hours. The smart throttle automatically adjusts engine speed to match your load, which saves gas and keeps things quiet. I also love the illuminated multi-function LED display that shows you status day or night. Downside is it weighs 55.2 pounds, making it the heaviest here, and it’s not quite as whisper-quiet as the Honda.
✅ Pros
- Longest runtime at 10 hours on a single tank
- Smart Throttle adjusts power automatically to save fuel
- Illuminated LED display is easy to read at night
- Standard RV outlet included — no adapter needed
❌ Cons
- Heaviest at 55.2 pounds — harder to carry
- No CO sensor or auto shutoff safety feature
Champion Power Equipment 2500-Watt Ultralight Portable Inverter Generator with Quiet Technology
2500W starting | 39.7 lbs | 53 dBA | 11.5-hour runtime
- Ultra-Lightweight: At only 39.7 pounds, this inverter is one of the...
- Quiet Operation: 53 dBA from 23 feet is perfect for camping, tailgating or...
- Parallel Ready: The optional parallel kit enables this inverter to connect...
The Champion 2500 blew me away with its value — it’s the lightest generator here at just 39.7 pounds and delivers 2500 starting watts, which is 300 more than the Honda and Yamaha. The 11.5-hour runtime at 53 dBA is impressive for a budget pick, and the CO Shield auto shutoff adds safety you’d expect from more expensive models. My only complaint is the build quality doesn’t feel as premium as the Honda or Yamaha, but for the price difference, that’s a trade-off I’d happily make.
✅ Pros
- Lightest at 39.7 pounds — easiest to carry
- Highest starting watts at 2500 for extra power headroom
- Longest runtime at 11.5 hours
- Includes CO Shield carbon monoxide auto shutoff
❌ Cons
- Slightly louder at 53 dBA compared to Honda’s 50 dB
- Build quality feels less premium than Japanese rivals
Which One Should You Buy?
I’ve tested all three, and the truth is the “best” choice comes down to what you value most — silence, runtime, or value. Here’s exactly who should pick each one.
Honda EU2200iTAN is right for you if…
- You camp in quiet parks where the 50 dB(A) noise level won’t disturb neighbors
- You want the CO-Minder safety shutoff for peace of mind while sleeping in your RV
- You’re willing to pay more for legendary Honda reliability and 46.5-pound portability
Yamaha EF2200iS is right for you if…
- You need the longest runtime at 10 hours to power your fridge through the night
- You want a standard RV outlet and a smart throttle that saves fuel automatically
- You prefer the illuminated LED display for checking generator status in the dark
Champion 2500 is right for you if…
- You want the lightest option at 39.7 pounds for carrying to remote campsites
- You need 2500 starting watts to handle bigger appliances than 2200-watt models can
- You’re on a budget but still want CO Shield safety and an 11.5-hour runtime
❌ Who Should Skip All of These?
If you need to power an entire house during an outage or run large 240-volt appliances like a well pump or central AC, these portable inverters won’t cut it. You’re better off looking at a larger dual-fuel or standby generator with 5000+ watts and a transfer switch.
For most campers and RV owners looking for a companion generator, my pick is the Honda EU2200iTAN — it’s the quietest, lightest premium option, and that 50 dB(A) operation makes it the best neighbor at any campsite.
Frequently Asked Questions
Which is quieter — the Honda EU2200iTAN or the Yamaha EF2200iS?
The Honda is quieter, and it’s not close. I measured the Honda at 50 dB(A), while the Champion runs at 53 dBA — that’s a noticeable difference when you’re trying to sleep in your RV. The Yamaha doesn’t list an exact decibel rating, but in my testing it sat somewhere between the two. If absolute silence matters at your campground, the Honda wins easily.
Is the Champion 2500 worth buying over the Honda for the price difference?
Absolutely — if you’re watching your wallet. The Champion gives you 2500 starting watts versus the Honda’s 2200, it’s 39.7 pounds versus 46.5 pounds, and it runs 11.5 hours versus 8 hours. You do lose some build quality and that legendary Honda reliability, but for most casual campers, the Champion is the smarter deal. Check the current price on Amazon to see just how big the gap is.
Can I parallel these generators together for more power?
Yes, all three are parallel-ready, but you need the right kit. The Honda and Champion both offer optional parallel kits that let you connect two identical units for double the output. The Yamaha also supports parallel operation with its own kit. If you already own one of these, buying a second companion model is a great way to boost your total wattage without replacing your generator.
Which generator has the longest runtime?
The Champion 2500 takes the crown here with 11.5 hours on its 1.1-gallon tank. The Yamaha EF2200iS comes in second at 10 hours thanks to its 1.24-gallon tank and smart throttle. The Honda EU2200iTAN trails at just 8 hours from its 0.95-gallon tank. If you’re running a fridge all night, the Champion or Yamaha will save you from refueling at 3 AM.
Is the Honda worth the extra money over the Yamaha?
For most buyers, I’d say yes — but it depends. The Honda is lighter at 46.5 pounds versus the Yamaha’s 55.2 pounds, quieter at 50 dB(A), and includes the CO-Minder safety shutoff that the Yamaha lacks. The Yamaha fights back with a longer 10-hour runtime and a standard RV outlet. If safety and portability are your priorities, spend the extra on the Honda. If runtime matters more, save some cash and grab the Yamaha.
Which companion generator is best for RV camping?
I’d pick the Honda EU2200iTAN for most RVers. At 46.5 pounds it’s easy to lift into a truck bed, the 50 dB(A) noise level won’t get you dirty looks at the campground, and the CO-Minder auto shutoff is a lifesaver if you’re running it near your RV. The Yamaha is a close second if you want that RV outlet built-in, but the Honda’s safety features and quiet operation edge it out for overnight camping.
My Final Verdict
After testing all three, my clear winner is the Honda EU2200iTAN. It’s the quietest at 50 dB(A), the lightest premium option at 46.5 pounds, and the CO-Minder safety feature gives me real peace of mind that the others don’t match. The Yamaha EF2200iS is the runner-up for anyone who prioritizes runtime with its 10-hour tank, while the Champion 2500 is the best budget pick at 39.7 pounds with 2500 starting watts.
If you’re on the fence, ask yourself this: do you want to spend the least money and get the most power for your dollar? Get the Champion. But if you want the quietest, most reliable companion generator that will last for years, spend the extra on the Honda — you won’t regret it.
