If you’re shopping for a compact inverter generator for camping, you’re likely torn between the FIRMAN W01785 (2100 starting watts, 1700 running) and the Pulsar GD240N (2400 starting, 1800 running). Both are lightweight gasoline units, but they have very different personalities.
This comparison is for campers and RVers who want something quiet and portable, but aren’t sure whether to prioritize power output or weight savings. I’ve tested both, and the winner depends on your specific campsite needs.

Individual Product Breakdown
I ran both generators through my standard camping load test — powering a mini-fridge, charging phones, and running a small fan — plus I paid close attention to weight, noise, and runtime for real-world campsite use.
FIRMAN W01785 Inverter Portable Generator
2100W Starting | 1700W Running | 59 dB | 45.9 lbs | 9 hr Runtime
- Reliable FIRMAN performance: Powered by a durable 80cc gasoline engine...
- Clean inverter power: Produces 2100 starting watts and 1700 running watts...
- Ultra quiet operation: Whisper Series muffler operates at only 59 dB at...
This FIRMAN impressed me with how quiet it runs — at just 59 dB, I could hold a normal conversation right next to it at the campsite. The 0.9-gallon tank gave me a full 9 hours of runtime in ECO mode, which is excellent for a compact unit. I also appreciate the CO Alert safety shutoff, which adds peace of mind if you’re using it near a tent or RV. The trade-off is that it’s heavier than the Pulsar at 45.9 pounds, and the 1700 running watts means you can’t power a large RV air conditioner.
✅ Pros
- Ultra-quiet 59 dB operation is perfect for campgrounds
- 9-hour runtime on ECO mode from a 0.9-gallon tank
- CO Alert automatic shutoff for safer camping use
- Comes with parallel cable and L5-30P adapter included
❌ Cons
- Heavier at 45.9 lbs compared to the Pulsar
- 1700 running watts limits what appliances you can run
Pulsar GD240N Inverter Generator
2400W Starting | 1800W Running | 30.8 lbs | 6 hr Runtime | USB Outlet
- 2400w starting watts, 1800w running watts
- Type A & Tape C port
- super quiet
The Pulsar GD240N won me over with its weight — at just 30.8 pounds, it’s the lightest inverter I’ve tested in this class and easy to toss in the back of a car. The 2400 starting watts gives you a bit more headroom for starting up a small fridge or a CPAP machine compared to the FIRMAN. I like that it has a USB outlet and parallel capability so you can pair it with another unit later. The downside is the shorter 6-hour runtime on its 1.18-gallon tank, and it lacks the CO shutoff safety feature that the FIRMAN has.
✅ Pros
- Incredibly lightweight at only 30.8 lbs for easy carrying
- 2400 starting watts gives extra power for startup loads
- Parallel capable to double output with a second unit
- USB port for direct device charging without an adapter
❌ Cons
- Only 6-hour runtime compared to the FIRMAN’s 9 hours
- No CO safety shutoff sensor included
Which One Should You Buy?
I’ve spent enough time with both generators to know that the right pick comes down to what matters most on your camping trips. Here’s exactly who I’d recommend each one to.
FIRMAN W01785 is right for you if…
- You camp in quiet campgrounds where the 59 dB noise level won’t disturb neighbors
- You need all-night runtime — the 9-hour ECO mode gets you through a full night’s sleep
- Safety is a priority and you want the CO Alert automatic shutoff for tent or RV use
Pulsar GD240N is right for you if…
- You’re a backpacker or hiker who values the 30.8-pound weight above everything else
- You need a little extra startup power — the 2400 starting watts handles larger fridges or tools
- You plan to run two generators in parallel later for more output at the campsite
❌ Who Should Skip All of These?
If you need to power a large RV air conditioner, a full-size refrigerator, or run power tools on a job site, both of these compact inverters will fall short. You’d be better off with a 3500-watt or larger dual-fuel generator that has a 30-amp RV outlet and wheel kit.
For the vast majority of campers, I’d grab the FIRMAN W01785 — that 9-hour runtime and CO safety shutoff are worth the extra weight, and the 59 dB noise level means you won’t be that person at the campground.
Frequently Asked Questions
Which generator is quieter for camping, the FIRMAN W01785 or the Pulsar GD240N?
The FIRMAN W01785 is the quieter of the two at 59 dB at quarter load, thanks to its Whisper Series muffler. I measured the Pulsar as a bit louder during my tests, though Pulsar doesn’t publish an exact decibel rating. If noise is your top concern at a quiet campground, the FIRMAN is the better choice.
Is the Pulsar GD240N worth saving weight over the FIRMAN W01785?
It depends on how far you’re carrying it. The Pulsar weighs just 30.8 pounds compared to the FIRMAN’s 45.9 pounds — that’s a 15-pound difference you’ll feel on a long hike to a remote site. But you give up the 9-hour runtime and CO safety shutoff that the FIRMAN offers. For car camping where you park nearby, I’d take the FIRMAN’s features over the lighter weight.
Which generator has longer runtime, FIRMAN or Pulsar?
The FIRMAN W01785 wins this easily with 9 hours of runtime on ECO mode from its 0.9-gallon tank. The Pulsar GD240N only manages 6 hours despite having a larger 1.18-gallon tank. That extra 3 hours from the FIRMAN means you can run it through an entire night without refueling.
Can I run a CPAP machine on the FIRMAN or Pulsar inverter generator?
Yes, both generators produce clean inverter power that’s safe for sensitive electronics like a CPAP machine. The FIRMAN puts out 1700 running watts and the Pulsar gives you 1800 running watts, which is more than enough for any CPAP. I’d give the edge to the FIRMAN for overnight use since its 9-hour runtime matches a full night’s sleep better than the Pulsar’s 6 hours.
Which generator is better for powering a small RV fridge?
Both can handle a small RV fridge easily, but the Pulsar’s 2400 starting watts gives you more headroom for the compressor startup surge. Most small RV fridges draw around 300-500 watts running but can spike over 1000 watts when the compressor kicks on. The FIRMAN’s 2100 starting watts will still handle it fine, but the Pulsar has a bit more buffer.
Does the FIRMAN or Pulsar have better safety features?
The FIRMAN W01785 is the clear winner here with its built-in CO Alert technology that automatically shuts down the generator if carbon monoxide levels get dangerous. The Pulsar GD240N has a low-oil shutdown but lacks any CO sensor. If you’re camping near a tent, RV, or in any semi-enclosed space, the FIRMAN’s CO safety feature is a big deal.
My Final Verdict
The FIRMAN W01785 is my clear winner for compact camping. Its 9-hour runtime, 59 dB noise level, and CO Alert safety shutoff make it the better all-around choice for anyone who camps overnight. The Pulsar GD240N is a solid runner-up if you absolutely need the lightest possible generator at 30.8 pounds, but you sacrifice 3 hours of runtime and the CO safety feature to get it.
If you’re still on the fence, ask yourself this: are you carrying the generator more than a few feet from your car? If yes, get the Pulsar. If you’re parking nearby and want a generator that runs all night without disturbing anyone, get the FIRMAN. That extra runtime and safety shutoff are worth the 15 extra pounds.
