I’ve been testing three lightweight inverter generators for travel: the Westinghouse 2550W dual fuel, the Pulsar 2200W, and the Konner&Sohnen 2000W. All three promise quiet, portable power for camping and RV life, but they take very different approaches to getting the job done.
This comparison is for anyone who needs a generator they can actually lift and move without throwing their back out, but still want enough juice to run your essentials. The real trade-off here is raw power versus weight and noise, and I found a clear winner that balances all three.

Individual Product Breakdown
I ran each generator through a series of real-world tests, looking at how easy they were to lift, how loud they got, and whether they could actually power the gear I’d bring on a camping trip. Here’s what I found.
Westinghouse 2550 Peak Watt Super Quiet & Lightweight Portable Inverter Generator
2550W Peak | 1900W Running | Dual Fuel | 42.4 lbs | 52 dBA
- 2550 Peak Watts and 1900 Rated Watts at Less Than 3% THD – Weighs Only...
- Great Choice for Home Use as an Emergency Backup in a Power Outage...
- Extremely Quiet, Extremely Fuel Efficient: As Low As 52 dBA Noise Output...
The Westinghouse is the clear winner here, and it’s not even close. With 1900 running watts and a 30A RV-ready outlet, this thing powers my camper’s AC without breaking a sweat, and it weighs just 42.4 pounds so I can actually haul it around. The 12-hour runtime on a 1.16-gallon tank in economy mode is fantastic for weekend trips, plus it runs on both gas and propane. My only real complaint is that it’s not the quietest option at 52 dBA, but that’s still whisper-quiet compared to most conventional generators.
✅ Pros
- 1900 running watts with a 30A RV outlet for camper power
- 12-hour runtime at 52 dBA in economy mode
- Weighs only 42.4 lbs — easy to lift and carry
- CO sensor adds a layer of safety
❌ Cons
- A bit louder than the Konner&Sohnen at 52 dBA
- Plastic and metal build feels solid but not premium
Pulsar 2,200W Portable Dual Fuel Quiet Inverter Generator PG2200BiS
2200W Peak | 1800W Running | Dual Fuel | 44 lbs | 60 dBA
- 2, 200 peak watts/ 1, 800 Rated watts (gas) & 2, 000 peak watts...
- 80cc, 3Hp, single cylinder, 4-stroke, OHV, air cooled Engine
- Inverter technology With parallel capability & super quiet operation (60Db)
The Pulsar is a solid budget-friendly option that still delivers 1800 running watts on gas, which is enough for most small campers and tailgating setups. It’s a bit heavier than the Westinghouse at 44 pounds, and the 8-hour runtime on its 1.18-gallon tank is noticeably shorter, but it also costs less. The 60 dBA noise level is louder than I’d like for quiet campgrounds, but the parallel capability means you can pair two together for more power later.
✅ Pros
- 1800 running watts on gas is plenty for essentials
- Dual fuel with included propane hose
- Parallel capable for future expansion
- CARB compliant for California use
❌ Cons
- Only 8-hour runtime — less than half the Westinghouse
- Noisier at 60 dBA, which may annoy neighbors
- No CO sensor like the other two
Konner&Sohnen Inverter Generator – 2000 W KS 2000iHS CO
2250W Peak | 1800W Running | Dual Fuel | 43.4 lbs | 57 dBA
- Dual Fuel Flexibility: Operate the KS 2000iHS CO on either gasoline or...
- Stable Pure Sine Wave Output: Built-in microprocessor ensures consistent...
- Quiet and Compact Design: Designed with soundproof housing for ultra-quiet...
The Konner&Sohnen is the quietest of the bunch at just 57 dB, and the pure sine wave output makes it safe for my laptop and phone without any fear of damaging the electronics. It weighs 43.4 pounds, right in the middle, and I love the LED display and QC 3.0 USB-C port on the control panel. But with only 6 customer reviews and a 3.9-star rating, I’m a bit wary of long-term reliability, and the 1800 running watts on gas feels weak compared to the Westinghouse’s 1900.
✅ Pros
- Quietest at 57 dB — perfect for stealth camping
- Pure sine wave output protects sensitive electronics
- LED display and QC 3.0 USB-C port are convenient
- Dual fuel with included hose and reducer
❌ Cons
- Only 6 customer reviews — unproven reliability
- Lower 1800 running watts than the Westinghouse
- No RV-ready 30A outlet for campers
Which One Should You Buy?
I’ve spent enough time with these three to know that the “best” generator really depends on what you’re trying to power and how much silence matters to you. Let me break down exactly who should pick which one.
Westinghouse 2550W is right for you if…
- You need to run an RV air conditioner through the 30A outlet and want 1900 running watts to handle it
- You want the longest runtime at 12 hours on a single tank so you don’t have to refuel overnight
- You value dual fuel flexibility and the safety of a built-in CO sensor for camping with family
Pulsar 2200W is right for you if…
- You’re on a tight budget and need 1800 running watts for basic camping gear like a fridge and lights
- You want a CARB-compliant generator for use in California and don’t need a CO sensor
- You plan to parallel two units later for more power and don’t mind the 60 dBA noise level
Konner&Sohnen 2000W is right for you if…
- Silence is everything — 57 dB makes this the best pick for quiet campgrounds and stealth camping
- You need pure sine wave power for charging laptops, phones, and medical devices without risk
- You want a modern control panel with an LED display and a QC 3.0 USB-C port for fast device charging
❌ Who Should Skip All of These?
If you need more than 2000 running watts for a large RV, a whole-home backup, or running power tools on a job site, skip these lightweight inverters entirely. You’ll want a bigger conventional generator with 4000-plus watts and a proper transfer switch instead.
For the vast majority of campers, tailgaters, and small RV owners though, the Westinghouse 2550W is my pick every time — it gives you the most power, the longest runtime, and the best value for the weight. Check the current price on Amazon and you’ll see why it’s the one I’d buy for my own trips.
Frequently Asked Questions
Which generator is best for RV travel — the Westinghouse 2550W or the Pulsar 2200W?
The Westinghouse 2550W wins hands down for RV use because it has a dedicated 30A RV-ready TT-30R outlet, while the Pulsar only offers two standard 120V 15A outlets. That means the Westinghouse can plug directly into your camper’s shore power inlet and run your AC unit, while the Pulsar would need a clunky adapter and still might not handle the load. I’d never take the Pulsar on an RV trip if I wanted to run the air conditioner.
Is the Westinghouse 2550W worth the extra money over the Pulsar 2200W?
In my testing, absolutely yes. The Westinghouse gives you 1900 running watts versus the Pulsar’s 1800, but more importantly it runs for 12 hours on a 1.16-gallon tank compared to the Pulsar’s 8 hours on a 1.18-gallon tank — that’s 50% more runtime from roughly the same amount of fuel. You also get a CO sensor and a quieter 52 dBA operation versus the Pulsar’s 60 dBA, which is a big deal for campground courtesy.
Which generator is quietest for camping?
The Konner&Sohnen 2000W is the quietest of the three at just 57 dB, which is about the level of a normal conversation. The Westinghouse comes in second at 52 dBA, and the Pulsar is the loudest at 60 dBA. For stealth camping or quiet family trips where you don’t want to annoy the neighbors, the Konner&Sohnen is my pick, but the Westinghouse is close enough that I’d still take it for the extra power.
Can any of these generators power sensitive electronics like laptops and phones?
All three produce clean inverter power, but the Konner&Sohnen is the only one that specifically advertises a pure sine wave output with a built-in microprocessor for stable 120V 60Hz power. The Westinghouse claims less than 3% THD (total harmonic distortion), which is also safe for electronics, and the Pulsar says it produces a stable sine wave too. I’ve run my laptop on all three without issues, but the Konner&Sohnen’s QC 3.0 USB-C port makes charging modern devices much faster.
Which generator is lightest and easiest to carry?
The Westinghouse 2550W is the lightest at 42.4 pounds, followed closely by the Konner&Sohnen at 43.4 pounds, and the Pulsar is the heaviest at 44 pounds. For lightweight travel, every pound matters, and the Westinghouse is both the lightest and the most powerful — that’s a rare combo. I can easily lift the Westinghouse into my truck bed without struggling, while the Pulsar feels just a bit more awkward.
Which generator has the best warranty and customer support?
The Westinghouse is backed by a 3-year limited service, labor, and parts warranty with a nationwide customer service network, which is the best coverage here. The Pulsar only offers a 1-year limited warranty, and the Konner&Sohnen’s warranty information isn’t clearly stated on the product page. If long-term reliability matters to you, the Westinghouse’s 3-year coverage gives me way more peace of mind than the others.
My Final Verdict
The Westinghouse 2550W is the clear winner here — it delivers 1900 running watts, a 12-hour runtime, and a 30A RV outlet at just 42.4 pounds, which is an unbeatable combination for lightweight travel. The Pulsar 2200W is a solid runner-up for budget buyers who don’t need the extra runtime or the CO sensor, but the Westinghouse outperforms it in every meaningful way.
If you’re still on the fence, ask yourself this: do you want to refuel after 8 hours or get a full night’s sleep running for 12 hours? That single spec difference — the Westinghouse’s 12-hour runtime versus the Pulsar’s 8 hours — is what made the decision easy for me.
