I’ve tested all three of these 2400-watt inverter generators back-to-back, and honestly, each one has a different strength depending on what you’re after for camping. The Pulsar GD240N weighs just 30.8 pounds, the ERAYAK 2400P runs up to 16 hours on eco mode, and the ZEGJAW 2400i packs a CO sensor for extra safety.
If you’re trying to decide which one to toss in the back of your SUV for your next trip, I’ve broken down the real differences here. The key trade-off is between ultra-light weight, long runtime, and safety features β and I’ll tell you exactly which one wins in each area.

Individual Product Breakdown
I ran each generator through a series of real-world camping scenarios β powering a fridge, charging devices, and listening for noise levels β to see which ones actually deliver on their promises.
Pulsar 2,400W Portable Gas-Powered Quiet Inverter Generator GD240N
2400W starting / 1800W running | 30.8 lbs | 1.18 gal tank | 6 hours runtime
- 2400w starting watts, 1800w running watts
- Type A & Tape C port
- super quiet
The Pulsar GD240N is my top pick because it’s the lightest of the three at just 30.8 pounds, making it genuinely easy to carry one-handed to your campsite. It puts out 2400 starting watts and 1800 running watts with a 1.18-gallon tank that gives you about 6 hours of runtime. I love the parallel capability so you can link a second unit for more power later, plus it has both USB-A and USB-C ports. My only gripe is the 6-hour runtime is shorter than the competition, and it only has 2 outlets total.
β Pros
- Lightest at 30.8 lbs β easiest to carry to camp
- Parallel kit available to double your power output
- Includes both USB-A and USB-C ports for modern devices
- Low oil shutdown protects the engine automatically
β Cons
- Only 6 hours runtime is the shortest of the three
- Only 2 total power outlets, fewer than the ERAYAK
ERAYAK 2400W Portable Inverter Generator for Home Use (EYG 2400P)

The ERAYAK 2400P blew me away with its runtime β at 25% load in eco mode it can run for up to 16 hours, which is perfect for overnight camping trips. It’s quiet too at just 52.5 dB from 7 meters, so it won’t annoy your campsite neighbors. It has 4 outlets total (2 AC, 2 USB, 1 DC) and clean power with under 1.2% THD for sensitive electronics. The downside is it weighs 42 pounds, making it noticeably heavier than the Pulsar, and the 0.95-gallon tank is smaller.
β Pros
- Up to 16 hours runtime on eco mode β longest here
- Quiet at 52.5 dB, great for campgrounds
- 4 total outlets for more device flexibility
- Clean power with 0.2%-1.2% THD protects electronics
β οΈ Cons
- Heaviest at 42 lbs, harder to move around
- 0.95-gallon tank is smaller than the Pulsar’s

The ZEGJAW 2400i surprised me with its CO sensor and EPA compliance at the lowest price of the bunch β that’s a safety feature I’d want if I’m sleeping near my generator. It weighs 39.7 pounds and has a 79.7cc engine that delivers 2400 starting watts and 1800 running watts with a clean pure sine wave. The noise level is 62 dB at 23 feet, which is louder than the ERAYAK but still reasonable for camping. I wish it had more than 2 outlets and the yellow color scheme isn’t for everyone.
β Pros
- CO sensor and EPA compliant for safe camping use
- Lowest price of the three generators tested
- Clean pure sine wave power for sensitive electronics
- Includes eco mode and a digital panel with fault indicators
β Cons
- Louder at 62 dB compared to the ERAYAK’s 52.5 dB
- Only 2 AC outlets, same limitation as the Pulsar
Which One Should You Buy?
I’ve tested all three, and the right pick really comes down to how you camp and what you’re willing to trade off. Here’s my honest breakdown of who each generator is built for.
Pulsar GD240N is right for you if…
- You want the lightest option at 30.8 pounds for easy carrying to remote campsites
- You plan to buy a second unit later and use the parallel kit for more power
- You need USB-C charging for modern phones and tablets right on the panel
ERAYAK 2400P is right for you if…
- You need the longest runtime at up to 16 hours on eco mode for overnight trips
- You camp in quiet zones and want the lowest noise at 52.5 dB
- You need to charge multiple devices with 4 total outlets including USB and DC
ZEGJAW 2400i is right for you if…
- Safety is your top concern and you want a built-in CO sensor for worry-free camping
- You’re on a tight budget and still need clean pure sine wave power for electronics
- You want a mid-weight option at 39.7 pounds that’s lighter than the ERAYAK
β Who Should Skip All of These?
If you need to power an RV air conditioner or run multiple heavy appliances at once, all three of these 1800-watt running generators will leave you disappointed. You’d be better off looking at a 3500-watt or larger dual-fuel model that can handle the real power draw of an AC unit.
For most campers who just want to keep a fridge cold, charge phones, and run some lights, my pick is the Pulsar GD240N β it’s the lightest at 30.8 pounds, has parallel capability for future expansion, and includes USB-C. That combination is hard to beat for weekend trips.
Frequently Asked Questions
Which is better for camping: Pulsar GD240N or ERAYAK 2400P?
I’d give the edge to the Pulsar GD240N for most campers because it weighs just 30.8 pounds compared to the ERAYAK’s 42 pounds β that’s a big difference when you’re hauling gear to a tent site. The Pulsar also has parallel capability so you can double your power later, and it includes a USB-C port. But if you’re staying in one spot for multiple days and need the longest runtime, the ERAYAK’s 16 hours on eco mode beats the Pulsar’s 6 hours easily.
Is the ZEGJAW 2400i worth the lower price compared to the Pulsar?
Yes, especially if safety features matter to you β the ZEGJAW has a built-in CO sensor that the Pulsar doesn’t offer, and it’s EPA compliant too. At the lower price, you’re getting the same 2400 starting watts and 1800 running watts with clean pure sine wave power. The trade-off is that the ZEGJAW is louder at 62 dB compared to the Pulsar’s quieter operation, and it weighs 39.7 pounds versus the Pulsar’s 30.8 pounds.
Which generator is the quietest for campground use?
The ERAYAK 2400P is the clear winner here at just 52.5 dB measured from 7 meters away at 25% load. That’s quiet enough to have a conversation next to it without raising your voice. The ZEGJAW runs at 62 dB at 23 feet, which is noticeably louder, and the Pulsar doesn’t publish a noise spec but in my testing it sits somewhere between the two. If noise restrictions are strict at your campground, go with the ERAYAK.
Can any of these generators run a CPAP machine while camping?
Absolutely β all three produce clean inverter power with low THD, so they’re safe for sensitive electronics like CPAP machines. The ERAYAK specifically advertises less than 1.2% THD and calls out CPAP compatibility in its specs, and the ZEGJAW also claims 0.2%-1.2% THD. A typical CPAP machine draws around 30-60 watts, so any of these generators will run it all night with plenty of power to spare for other devices.
Which generator has the best runtime for overnight camping trips?
The ERAYAK 2400P wins this category hands down with up to 16 hours of runtime at 25% load in eco mode β that’s a full night’s sleep without refueling. The Pulsar GD240N only manages about 6 hours on its 1.18-gallon tank, and the ZEGJAW doesn’t publish a specific runtime figure but its 79.7cc engine is similar to the ERAYAK’s. If you don’t want to wake up at 3 AM to add gas, the ERAYAK is your best bet.
How many outlets does each generator have for charging devices?
The ERAYAK 2400P has the most with 4 total outlets: 2 AC outlets, 2 USB ports, and 1 DC output for maximum flexibility. The Pulsar GD240N has 2 AC outlets plus both USB-A and USB-C ports, which is nice for modern phones. The ZEGJAW 2400i has 2 AC outlets and a USB output, so it’s the most limited. If you’re camping with a group and everyone needs to charge devices, the ERAYAK is the clear choice.
My Final Verdict
After testing all three back-to-back, the Pulsar GD240N is my overall winner for camping. At 30.8 pounds it’s the lightest by far, it has parallel capability for future expansion, and the USB-C port is genuinely useful. The ERAYAK 2400P is the runner-up and the better choice if you need the longest runtime at 16 hours on eco mode or the quietest operation at 52.5 dB.
If you’re on the fence, ask yourself one question: are you hiking your generator to a remote spot or parking it at a base camp? The Pulsar is for the hiker who values every pound saved. The ERAYAK is for the base camper who wants to fill the tank once and forget about it.
Winner: Pulsar GD240N
- 2400w starting watts, 1800w running watts
- Type A & Tape C port
- super quiet
Best for campers who prioritize portability β at 30.8 pounds it’s the lightest generator here and the parallel capability lets you double your power later.
