Product Overview
The ONLYFIRE Portable Camping Gas Stove (model GS333) is engineered for outdoor enthusiasts who demand performance without sacrificing portability. This compact yet powerful camp stove delivers 3500W of efficient cooking power—enough to rival much larger stoves—while remaining lightweight and easy to carry. Whether you’re backpacking through rugged trails, setting up at a lakeside campsite, or preparing a quick meal during a picnic, the GS333 ensures reliable performance in diverse environments. Its built-in piezo ignition system provides instant spark activation, eliminating the need for matches or flint. The stove’s thoughtful design includes foldable pot supports, a durable construction, and an included carry bag, making it ideal for travelers who value both function and convenience.
Key Features
- Portable Backpacking Design: The GS333 is specifically crafted for compact storage and effortless transport. Its foldable pot supports allow for quick assembly and tidy stowage, fitting seamlessly into backpacks, gear bags, or camping kits. This makes it perfect for thru-hikers, weekend adventurers, or anyone seeking minimalist yet effective outdoor cooking solutions.
- Piezo Ignition System: Featuring a built-in electric spark ignition, the stove starts reliably with the push of a button. Unlike traditional manual igniters, this system works consistently in various weather conditions—rain, wind, or cold temperatures—ensuring you can cook when it matters most. No extra tools, no fumbling with matches; just fast, safe starts every time.
- Multi-Fuel Compatibility: One of the standout advantages is its adaptability across fuel types. The GS333 comes with adapters for both isobutane cartridges and standard 1LB propane cylinders. This means you can choose your preferred fuel based on availability, trip duration, or regional preferences. Whether you’re in North America using propane or traveling internationally with isobutane, this stove keeps pace with your journey.
- High-Performance Output: Despite its small footprint, the stove generates 3500 watts of heating power—comparable to larger models twice its size. This high output enables rapid boiling, efficient heat transfer, and shorter cooking times, helping conserve fuel during extended trips or high-altitude adventures where efficiency is critical.
- Durable Construction: Built from thick-gauge stainless steel and reinforced with copper triangle brackets, the stove offers exceptional stability and longevity. The serrated pot-support arms grip standard-sized pots securely, minimizing slippage on uneven ground or windy surfaces. This robust build ensures consistent performance season after season.
- Included Carry Bag: A dedicated nylon carry bag is provided to protect the stove and keep all components organized during transit. It shields against dirt, moisture, and damage while compressing the folded stove into a space-efficient shape. The bag itself is lightweight and often doubles as a cleaning cloth or ground cover.

Benefits & Use Cases
The ONLYFIRE GS333 excels in real-world outdoor scenarios where every detail impacts usability. For thru-hikers and ultralight backpackers, its compact form factor reduces pack weight without compromising on meal readiness. The 3500W output allows for quick pasta boils, hot coffee in the morning, and even frying small items—all while using less fuel than bulkier alternatives. At altitude or in cold climates, consistent flame control helps maintain efficiency where other stoves may struggle.
For day hikers and families heading out for a picnic, the intuitive piezo ignition means setup takes seconds. You don’t need to worry about wet matches or unreliable lighters. The stable cooking platform holds pots securely on rocky slopes or grassy fields, reducing spills and improving safety. The dual-fuel capability also adds peace of mind during international travel, where local fuel standards may vary.
Beyond cooking, the included carry bag enhances organization—keeping the stove, adapters, and any spare parts together. It’s also useful for protecting gear during storage or transport. Because the stove doesn’t come with fuel cartridges, users must supply their own compatible isobutane or propane canisters, which ensures compatibility with personal preferences or regional availability.
Overall, the GS333 strikes a rare balance between power, portability, and practicality—making it a top choice for serious campers, hikers, and outdoor cooks who refuse to compromise on quality.
Important Notes
Always operate the stove in well-ventilated outdoor areas only. Never use indoors, in tents, or in enclosed spaces due to carbon monoxide risks. Before each use, inspect all fuel connections for leaks by applying soapy water—bubbles indicate a leak requiring immediate attention. Store the stove and adapters separately when not in use, and avoid exposing them to extreme temperatures or prolonged sunlight, which could degrade components over time.
The carry bag offers protection but is not waterproof or storm-rated. For long-term storage, keep the stove in a dry, cool place and ensure the gas valves are fully closed to prevent accidental discharge. While the piezo ignition is highly reliable, keep batteries charged if applicable (note: this model uses integrated piezoelectric crystals and does not require external batteries).
This product is intended strictly for outdoor recreational use. Do not modify fuel lines or attempt to use unsupported fuel types, as this may result in unsafe operation or void warranty coverage.
