I have been cooking at campsites for going on twenty seasons. I have used camp stoves that ran on white gas, ones that only took the big green propane bottles, and plenty that demanded a specific isobutane canister I could never find at the gas station at 6pm on a Friday. Every one of those setups has put me in a bind at least once. The dual-fuel stove fixed that problem and a handful of others I did not even know I had. The Gas One GS-3400P is the one sitting in my truck right now, rated 4.6 stars across nearly 15,000 reviews, and it costs less than a decent campsite dinner for two.
Below are the ten reasons I keep recommending it to every new camper in my group, and why a dual-fuel setup earns its spot in any camping kit. If you want the full field-test breakdown, my Gas One GS-3400P long-term review has two full seasons of notes. And if you are trying to decide between this and the Coleman BottleTop, I put them through the same meal side by side in the Gas One vs Coleman BottleTop comparison.
If your current stove leaves you hunting for the right canister, this one ends that problem for good.
The Gas One GS-3400P runs on propane or butane, weighs next to nothing, and costs less than you expect. Over 14,000 campers have bought it. Here is the current price on Amazon.

This is the whole argument for a dual-fuel stove in one sentence. At a gas station in a small town the night before a trip, you might find a rack of green 1lb propane cylinders. At a camping supply store, you will probably find butane canisters too. The GS-3400P takes both. You grab whatever is on the shelf and you cook breakfast. No special ordering, no panic, no deciding between the stove and the trip.
Butane Burns Cleaner and Quieter When You Have a Choice
When I am at a well-stocked campsite and I have both fuels on hand, I reach for butane. It burns with less odor, the flame is slightly easier to control at low settings, and the hiss is quieter. That matters more than I thought it would the first time I tried to have a conversation at the picnic table while someone else was cooking on a roaring single-fuel propane burner. The GS-3400P lets you pick based on conditions, not based on what the stove forces you to use.
Propane Performs Better in Cold Weather
Butane starts to struggle when temperatures drop below about 32 degrees Fahrenheit. The vapor pressure drops and the flame gets weak and inconsistent. Propane handles cold mornings better. On a November campout in the Appalachians where the thermometer read 28 degrees at 6am, I was glad I had propane in the canister instead of butane. The GS-3400P lets you switch fuel based on the forecast, not guess and hope.
It Weighs Less Than a Full Water Bottle
The GS-3400P without fuel comes in at about a pound. That is light enough to fit in a daypack on a shoulder-season trip where you want a reliable stove but cannot afford to carry dead weight. I have packed it as a backup stove on trips where the main cooking setup was a group camp kitchen, and I barely noticed it was there. For backpackers moving toward ultralight who still want the dual-fuel flexibility, this stove is a serious option.
The first time I grabbed a green propane cylinder off a gas station shelf at 7pm and just cooked dinner without any adapter or second-guessing, I understood why dual-fuel matters. That convenience is real every single trip.
The Burner Output Is Enough for Real Cooking
At 7,650 BTU on propane, the GS-3400P is not a performance racing stove. But it is enough to bring a 2-quart pot of water to a rolling boil in about four minutes, keep a skillet hot enough to sear an egg, and simmer chili without scorching the bottom. I have cooked full breakfasts on it for four people by working in batches. It is a real cooking tool, not a novelty.
The Flame Control Is Precise Enough to Simmer
A lot of budget camp stoves have two settings: too hot and off. The GS-3400P has a smooth valve that lets you dial from a high boil down to a low simmer without any dead zones in between. I have kept a pot of oatmeal at a gentle bubble for ten minutes without standing over it. That level of control matters when you are trying to cook something that needs patience and not just a fast boil.
The Piezo Igniter Works Reliably
Some camp stove igniters turn into expensive paperweights after a few wet weekends. The GS-3400P has a push-button piezo igniter that has lit first or second click for me on every trip, including a damp October morning when everything at the campsite was soaked. I still carry a lighter as backup because that is just smart camping, but I have never needed it for this stove. That is a better track record than most igniter systems I have used.
It Packs Flat and Stores Without Drama
The GS-3400P folds down small. The legs fold in, the grate folds flat, and the whole unit fits in its own carrying case or slides into a stuff sack without needing to be carefully packed around. I have thrown it in the back of the truck between a cooler and a pack many times without any damage. The build is solid enough to handle gear bag life without cracking a valve or bending a support arm.
At This Price, You Can Buy a Backup Without Guilt
The GS-3400P costs less than thirty dollars. That means you can buy one for the truck, one for the gear closet, and one to lend to a friend who keeps borrowing yours. At that price, losing one in a gear pile-up or retiring one after a hard season is not a catastrophic decision. I know campers who use one dedicated butane-only stove for mild weather and keep a GS-3400P as a propane backup for cold trips. Total cost for that two-stove system is still under seventy dollars.
Nearly 15,000 Campers Have Vetted It in the Field
I can tell you what I found after two seasons of use, but there is also the matter of 14,939 Amazon reviews sitting at 4.6 stars. That sample size covers a lot of conditions, a lot of campers, and a lot of trips I have never been on. High altitude, coastal humidity, desert heat, winter cold. The ratings hold across all of it. A piece of gear with that many reviews at that average rating is not getting lucky. It is consistently doing its job.
What I Would Skip
The GS-3400P is a single-burner stove. If you are cooking for a group of six and want to run scrambled eggs and bacon at the same time, you need a two-burner setup. It is also worth knowing that the BTU output is solid but not aggressive. If you are trying to boil large quantities of water fast for dehydrated meals on a high-altitude backpacking trip, a higher-output canister stove built specifically for that use case may serve you better. The GS-3400P is at its best for weekend car-camping and light backpacking where fuel flexibility and small size matter more than maximum BTUs.
Ten reasons sounds like a sales pitch. But every one of these is something I have run into on an actual trip. Dual-fuel flexibility is not a spec-sheet checkbox. It is the reason dinner happens when your usual canister is sold out at the camp store.
Still running single-fuel? This is the upgrade that solves the problem before it ruins a trip.
