If you’re shopping for a quiet inverter generator for camping, you’re probably stuck between the WEN 3600 (56360i), the PowerSmart 3600, and the GENMAX 3300 (GM3300i). All three are lightweight, gas-powered, and built to run sensitive electronics without disturbing the peace at your campsite.
I tested these three side-by-side to see which one actually delivers on quiet operation and real-world power. The big trade-off here is runtime versus portability, and I’ll show you exactly which generator fits your camping style best.

Individual Product Breakdown
I ran each generator through a real camping load test — powering a small RV AC, charging phones, and running lights — to see which one actually delivers on the specs that matter for quiet nights outdoors.
WEN 3600-Watt Portable Inverter Generator
3600W surge / 2900W rated | 46.3 lbs | 1.6 gal tank | 5 hours runtime
- 149cc engine generates up to 3600 surge watts and 2900 rated watts
- Produces clean power to prevent damage to sensitive electronics such as...
- Ultralight body weighs in at a mere 46 pounds for easy transport and torage
The WEN 56360i is the lightest of the bunch at just 46.3 pounds, which makes a huge difference when you’re hauling it from the truck to the campsite. I love the fuel shutoff feature that runs the carburetor dry before shutdown — it extends the generator’s lifespan and saves me from having to drain it manually. The 1.6-gallon tank gives you 5 hours of runtime at full load, which is solid for a weekend trip. My only gripe is the 2900 rated watts might struggle if you’re trying to run a big RV AC and a microwave at the same time.
✅ Pros
- Ultralight at 46.3 lbs — easiest to carry of the three
- Fuel shutoff extends engine life automatically
- Includes TT-30R RV receptacle for direct camper hookup
- Three-year warranty is the longest of the group
❌ Cons
- Rated watts at 2900 — less headroom than the PowerSmart
- Only 5 hours runtime at full load
PowerSmart 3600-Watt Portable Inverter Generator
3600W surge / 3200W rated | 50.7 lbs | 1.3 gal tank | 10 hours runtime
- 𝐏𝐨𝐰𝐞𝐫 𝐎𝐮𝐭𝐩𝐮𝐭: produces 3800 peak watts and...
- 𝐋𝐨𝐧𝐠 𝐑𝐮𝐧𝐭𝐢𝐦𝐞: up to 6 hours at 25% load...
- 𝐐𝐮𝐢𝐞𝐭 𝐎𝐩𝐞𝐫𝐚𝐭𝐢𝐨𝐧: features a low...
The PowerSmart surprised me with its 10-hour runtime at 25% load — that’s a full night of sleep without refueling. It puts out 3200 rated watts, which is 300 more than the WEN, so it handles bigger loads like a 15,000 BTU RV air conditioner more confidently. The 50.7-pound weight is still manageable, but you’ll feel the difference compared to the WEN after carrying it across a campsite. I also wish the included accessories were more generous — you only get a wrench in the box.
✅ Pros
- 10-hour runtime is best in class for overnight camping
- 3200 rated watts — more power headroom than competitors
- Parallel capable for doubling power later
- 4.6 out of 5 stars from 250 reviews — very reliable
❌ Cons
- Heavier at 50.7 lbs than the WEN
- Only includes a wrench — no extra accessories
- 1.3 gal tank is smaller than the WEN’s
GENMAX Portable Generator, 3300W Ultra-Quiet Gas Engine
3300W surge / 3000W rated | 51.8 lbs | 1.5L tank | 6 hours runtime
- 【Powerful Engine And Safe For Sensitive Electronics 】The GENMAX...
- 【Ultralight And Small Size】The weight of this generator is only 47 lbs...
- 【Very Quiet & High Fuel Efficiency】 Fully enclosed design dramatically...
The GENMAX GM3300i is the quietest option here at 60 dBA at quarter load — you can actually hold a conversation 10 feet away while it runs. It’s also the only one with a CO Detect shutdown sensor, which is a nice safety net if you’re camping near your tent. The 51.8-pound weight makes it the heaviest of the three, and the 1.5-liter tank is tiny, giving you just 6 hours of runtime. For the price, the Eco Mode helps stretch fuel efficiency, but you’ll be refilling more often than with the PowerSmart.
✅ Pros
- Quietest at 60 dBA — great for noise-sensitive campsites
- CO Detect shutdown sensor for carbon monoxide safety
- Eco Mode improves fuel efficiency at partial loads
- Parallel ready to combine two units for more power
❌ Cons
- Heaviest at 51.8 lbs — not ideal for frequent moving
- 1.5L tank means frequent refueling stops
- Only 3000 rated watts — lowest power output of the three
Which One Should You Buy?
I’ve spent enough time with all three to know there’s no single “best” generator — it really comes down to whether you value portability, runtime, or quiet operation most. Here’s who each one is built for.
WEN 3600-Watt Portable Inverter Generator is right for you if…
- You carry your generator any real distance — at 46.3 pounds it’s the lightest to lug from the truck to your campsite
- You want a direct RV hookup with the built-in TT-30R receptacle for your camper
- You care about long-term reliability and want a three-year warranty plus fuel shutoff to protect the engine
PowerSmart 3600-Watt Portable Inverter Generator is right for you if…
- You need power through the whole night — the 10-hour runtime at 25% load means no 2 a.m. refueling trips
- You’re running a 15,000 BTU RV air conditioner and need the extra 300 rated watts over the WEN
- You might want to double your power later with the parallel connection kit
GENMAX Portable Generator, 3300W Ultra-Quiet Gas Engine is right for you if…
- You camp in quiet zones or near other people — 60 dBA at quarter load is the quietest of the bunch
- Safety is your top concern and you want the CO Detect shutdown sensor for peace of mind
- You’re on a tighter budget and value the Eco Mode to stretch fuel efficiency at partial loads
❌ Who Should Skip All of These?
If you need to power a whole house during an outage or run heavy-duty tools like a welder or large air compressor, none of these 3600-watt-class inverters will cut it. You’re better off looking at a dual-fuel or open-frame generator with at least 5000 running watts and a larger fuel tank for extended home backup.
For the typical quiet camper who wants something portable and reliable, my pick is the WEN 3600 — it’s the lightest, has the best warranty, and includes an RV-ready outlet right out of the box. Check the current price on Amazon to see if it fits your setup.
Frequently Asked Questions
Which generator is lighter for camping — the WEN 3600 or the PowerSmart 3600?
The WEN 3600 is the clear winner here at 46.3 pounds versus the PowerSmart at 50.7 pounds. That 4.4-pound difference might not sound like much, but I felt it immediately when I carried both across a field. If you’re hauling your generator any real distance on foot, I’d go with the WEN every time.
Is the PowerSmart 3600 worth more than the WEN 3600 for longer trips?
Yes, if runtime is your priority. The PowerSmart gives you 10 hours at 25% load, while the WEN only manages 5 hours at full load. That’s a full night of sleep versus waking up to refuel. But the WEN has a larger 1.6-gallon tank and a fuel shutoff feature that protects the engine, so it’s better for people who store their generator for long periods.
Which generator is quietest for campsites with noise restrictions?
The GENMAX GM3300i is the quietest at 60 dBA at quarter load — you can hold a normal conversation 10 feet away. The WEN and PowerSmart are both described as “super quiet” but neither publishes a specific decibel rating like the GENMAX does. For strict quiet-hour campsites, the GENMAX is your best bet.
Can the WEN 3600 and GENMAX 3300 power an RV air conditioner?
The WEN 3600 puts out 2900 rated watts and the GENMAX puts out 3000 rated watts, so both can handle a standard 13,500 BTU RV AC that draws around 1500-2000 watts. But the PowerSmart 3600 gives you 3200 rated watts, which gives you more headroom for a 15,000 BTU unit plus other appliances. I’d pick the PowerSmart if you’re running a bigger AC.
Which generator has the best warranty for long-term reliability?
The WEN 3600 comes with a three-year limited warranty, which is the best of the three. The PowerSmart has a two-year warranty, and the GENMAX also offers a three-year warranty with free lifetime technical support. If you want the longest coverage and a brand known for customer service, I’d lean toward the WEN or GENMAX.
Is the GENMAX 3300 a good budget option compared to the WEN 3600?
The GENMAX 3300 is often priced lower than the WEN 3600, but you’re trading 600 fewer surge watts and a smaller 1.5-liter tank that gives you only 6 hours of runtime. It also weighs 51.8 pounds, making it the heaviest of the three. For the extra money, the WEN gives you more power, lighter weight, and a better fuel system — I think it’s worth the upgrade for most campers.
My Final Verdict
For quiet camping, my winner is the WEN 3600 (56360i). It’s the lightest at 46.3 pounds, has the longest three-year warranty, and includes a fuel shutoff that protects the engine during storage — all while delivering 3600 surge watts and an RV-ready TT-30R outlet. The PowerSmart 3600 is the runner-up, and it’s a better pick if you absolutely need the 10-hour runtime for overnight trips without refueling.
If you’re still on the fence, ask yourself this: do you want to carry less weight and get better long-term reliability, or do you need the extra runtime and power headroom for a bigger RV AC? That single question will point you to the right generator.
