Gas One GS-3400P Propane or Butane Stove review

Have you been searching for a compact dual-fuel stove that promises flexibility for both camping trips and emergency kits?

My overall impression

I like how the Gas One GS-3400P presents itself as a practical, versatile option for people who want a single stove that can run on either butane or propane. The combination of a carry case, an included propane regulator, and piezo ignition makes it feel like a complete package right out of the box.

First impressions and unboxing

When I opened the box, the stove and its components felt solid and well-packaged, which is reassuring for something intended to travel with me. Everything was arranged to minimize rattling and damage during shipping, and the included instructions were straightforward to follow.

What’s in the box

Inside the package I found the Gas One GS-3400P stove, a carrying case, a propane converter/regulator, and a user manual, along with some basic hardware for installation. There were no fuels included, so I had to plan to buy the appropriate butane cartridges or a propane cylinder separately.

Build quality and materials

The stove uses a mix of stamped metal and heat-resistant materials that look durable enough for repeated use outdoors. I noticed the pot supports are sturdy and the control knob moves smoothly, which gives me confidence when placing heavy cookware on it.

Fuel compatibility and how it works

I appreciate that the GS-3400P accepts both butane cartridges and standard propane cylinders, so I can choose fuel based on availability and temperature conditions. The unit operates on a single butane cartridge (8 oz) or a propane cylinder (16.4 oz) with the provided converter/regulator, which makes fuel logistics much easier for mixed-use scenarios.

Using butane

When I use butane cartridges, the stove is simple to set up: insert the cartridge and engage the ejection/locking mechanism according to the manual. Butane works great in moderate to warm temperatures and is very convenient for urban trips where cartridges are sold in convenience stores.

Using propane with the included regulator

To use propane, I attach the included converter/regulator to a 16.4 oz propane cylinder and secure the connection to the stove, then turn on the gas and ignite. Propane is the better choice if I expect cold temperatures or need greater reliability for extended cooking sessions, since it remains vaporized at lower temperatures than butane.

Switching fuels and safety notes

Switching between butane and propane is straightforward but I always follow the manual step-by-step to avoid cross-threading or incomplete seals. I also make it a point to check for leaks and to never interchange fittings or force components into place.

Ignition system and controls

The automatic piezo-electric ignition is one of my favorite features because it eliminates the need to carry lighters or matches. The control knob provides smooth, graduated adjustment, and so I can go from a rolling boil to a low simmer without fuss.

Piezo-electric ignition

The built-in piezo igniter produces sparks reliably in normal outdoor conditions, and it’s handy when I’m using the stove in an emergency situation. If the weather is wet or extremely windy, I recommend using a windscreen or manual ignition backup, since spark performance can be affected by conditions.

Heat control and flame behavior

The adjustable heat dial gives me good control over flame intensity and I’ve been able to simmer as well as achieve rapid boil times for small pots. Flames are stable on flat ground and the burner distributes heat evenly enough for frying, boiling, and simmering.

Safety features and real-world safety checks

I feel more secure knowing the stove has a built-in pressure sensor cartridge ejection system and a gas flow cut-off mechanism for butane, which are important for preventing hazardous pressure conditions. I still perform my own routine safety checks such as inspecting seals, listening for leaks, and visually monitoring flame color and behavior.

Pressure sensor cartridge ejection and gas cut-off

The cartridge ejection mechanism is designed to release a cartridge if abnormal pressure is detected, and the gas flow cut-off is meant to stop gas delivery in potentially unsafe situations. While these are useful safety layers, I treat them as backups and continue to practice manual safety procedures whenever I operate the stove.

Leak testing and safe operation

Before I ignite the GS-3400P I perform a simple leak test by applying soapy water to connections and watching for bubbles when the gas is turned on at low pressure. I always run the stove in well-ventilated areas, avoid using it inside tents or small enclosed spaces, and keep combustible materials clear of the burner.

Performance in cooking

In everyday use I found the stove capable of handling most typical campsite cooking tasks, from boiling water for coffee to frying and simmering stews. The output is dependable for small to medium pots and pans, and the stove’s dual fuel nature gives me flexibility in fuel selection depending on conditions.

Boiling times and simmering

Boiling a liter of water on a calm day felt reasonable and comparable to other compact stoves I’ve used; I could reduce heat to maintain a simmer without hunting for a delicate balance. If I needed faster boil times for larger pots or heavier meals, I would pair the stove with efficient cookware and possibly use a windshield.

Stability and wind resistance

The pot supports offer good stability for small to mid-size cooking vessels, though I avoid using oversized or wobbly cookware that could unbalance the stove. In windy conditions I use a lightweight windshield or natural shelter to protect the flame, as wind will reduce efficiency and can cause uneven heating.

Portability and carrying case

I like that the stove packs into a compact carrying case that makes transport neat and organized, which is ideal for stashing in a vehicle or emergency kit. The case helps protect the stove components and makes it easy for me to grab everything at once when I’m heading out.

Size, weight, and packing

The unit is small enough to fit in a car trunk, camper, or large backpack and the included regulator and hardware tuck into the case pockets. While it’s not the lightest stove available, the trade-off for dual-fuel versatility and added safety features feels worth the modest weight.

Suitability for emergency kits and camping

Because the GS-3400P accepts common propane cylinders and convenient butane cartridges, it’s a practical addition to an emergency preparedness kit. I keep mine alongside spare seals and a multi-tool, and I appreciate that it can switch fuels based on what’s accessible during a disruption.

Maintenance and cleaning

I keep the GS-3400P in good working order by wiping it down after use and periodically cleaning the burner ports to avoid clogging. Simple preventative maintenance saves me from inconvenient failures when I need the stove most.

Routine cleaning steps

After the unit cools, I remove debris and wipe surfaces with a damp cloth, and I use a soft brush to clear burner ports if I notice uneven flame patterns. I avoid soaking any parts that contain seals or mechanical components and I follow the manufacturer’s guidance for deeper cleaning.

Storage tips and winter considerations

For long-term storage I remove any fuel cartridges and store them separately, then place the stove in its carrying case in a dry, cool place. I’m careful with butane in cold weather because it has reduced vapor pressure at low temperatures, so I switch to propane when I expect sub-freezing conditions.

Troubleshooting common problems

If something goes wrong, many issues have simple fixes that I can address quickly in the field or at home. I keep a few spare basic items like extra sealing rings and a small set of tools in my emergency kit for routine troubleshooting.

Ignition fails to spark

If the piezo igniter doesn’t spark, I first check that there’s fuel pressure and that the gas is flowing, then I inspect the igniter electrode for damage or fouling. As a backup, I use a long-reach lighter or match if the conditions allow and if I’ve ensured safe, well-ventilated conditions.

Fuel flow issues and cartridge ejection

If the cartridge ejector triggers or the propane regulator doesn’t seat properly, I power down, remove the fuel source, and inspect the fittings for dirt or misalignment. Often cleaning connection points and reseating the regulator or cartridge solves the problem; if not, I replace worn seals or consult the manual.

Pros and cons

I like to weigh strengths and weaknesses before recommending a stove, and the GS-3400P has several advantages as well as some limitations to keep in mind.

Pros:

• Dual-fuel flexibility allows use of butane cartridges or propane cylinders.
• Included propane converter/regulator and carrying case add value.
• Piezo-electric ignition simplifies lighting without lighters or matches.
• Safety features such as pressure ejection and gas cut-off provide an extra safety layer.

Cons:

• Fuel is not included, so initial setup requires purchasing cartridges or cylinders.
• Butane performance can drop in cold weather, requiring a switch to propane.
• Not the lightest or smallest option for ultralight backpacking; better suited for car camping or emergency kits.

Who should buy this stove

I would recommend the GS-3400P for car campers, families, and people putting together an emergency preparedness kit who want flexible fuel options. It’s also a strong choice for those who prefer a ready-to-go package with a regulator and carry case included rather than buying accessories separately.

Comparison with alternative stoves

I often compare dual-fuel portable stoves like this one to single-fuel butane stoves and propane-only backpacking stoves to determine trade-offs based on use case and weight.

Single-fuel butane stoves

Single-fuel butane stoves are typically lighter and simpler, but they limit you to butane cartridges which perform poorly in cold environments. If you live or camp in warm climates and prioritize minimalism, a butane-only stove could be adequate, but the GS-3400P’s flexibility is more practical across varied conditions.

Propane-only backpacking stoves

Propane-only stoves, especially canister stoves that use isobutane/propane mixes, are often optimized for ultralight backpacking and deliver consistent cold-weather performance. The GS-3400P is bulkier than many backpacking rigs, but its ability to accept larger propane cylinders makes it better for longer outings or situations where you don’t want to change canisters frequently.

Buying advice and accessories

When I purchase a stove like the GS-3400P, I consider which fuels I’ll use, the accessories I need, and small spare parts that can prevent downtime. Planning ahead helps me avoid delays when I rely on the stove for a trip or during an emergency.

Recommended spare parts and accessories

I carry spare O-rings/seals, a small cleaning brush for the burner, a manual lighter as backup, and a compact windshield for windy conditions. If you plan to use propane frequently, buying a second propane cylinder or an adapter for larger tanks can be useful depending on local availability and regulations.

Fuel sourcing and legal considerations

Butane cartridges and disposable propane cylinders are widely available at outdoor retailers, hardware stores, and larger grocery chains, but availability can vary by region. I also check local airline or transport regulations if I plan to travel with the stove, since fuel restrictions apply to air travel and some forms of ground transport.

Final thoughts and rating

Overall, I find the Gas One GS-3400P to be a capable, well-rounded dual-fuel stove that balances convenience, safety, and practicality for a range of outdoor and emergency uses. For anyone who wants the option to use either butane or propane and prefers a tidy package with a carrying case and regulator included, this stove represents a strong value.

If I had to summarize why I keep it in my gear rotation: the dual-fuel flexibility, piezo ignition, and sensible safety features make it a dependable choice for car camping and emergency preparedness, while the included accessories reduce the number of separate purchases I need to make.
