What You’re Getting

A 230g resealable screw-on gas cartridge featuring a four-season blend of 45% Butane, 28% Isobutane, and 26% Propane, suitable for various camping stoves and appliances.

First impressions

The 230g Companion Pro Fuel cartridge is incredibly compact, measuring only 11 cm high and 8.5 cm wide. When you pick it up, the 383g total weight feels heavy enough to be substantial, but light enough to justify its inclusion as Ultralight Gear for hiking. We used it with a small screw-on stove, which twisted on easily and formed a great, compact cooking solution that packs away neatly.

The aluminium casing is simple an tough, however we did notice it dents quite easily. So handling it with care is important when loading and unloading your gear. We also like the simple but effective plastic lid that covers the valve, which is great for protecting the screw thread when the cartridge is stored.

Materials & Build Quality

The quality of a gas cartridge lies in two components: the shell and the mixture inside. The Companion Pro Fuel features an aluminium-cased construction, which is lightweight but does need care to avoid dents that could compromise safety. The main material feature, however, is the gas blend itself.

The contents are a mix of 45% Butane, 28% Isobutane, and 26% Propane. This specific three-gas blend is what earns it the ‘four-season’ designation. The inclusion of Propane (which has a lower boiling point of -42 °C) and Isobutane (boiling point of -12 °C) is vital for ensuring gas pressure when temperatures drop below freezing, as pure Butane stops performing well at 0 °C.

The resealable valve itself is built to EN417 and DOT2P safety standards, which gives confidence that you can safely screw and unscrew it multiple times without leakage. Overall, the materials are a smart, multi-purpose combination designed for wide temperature range performance.

Ergonomics & Weight

Weighing only 383g in total, the Companion Pro Fuel butane gas cartridge is an effortless addition to a hiking pack or an emergency backup in your 4WD. The compact size of 11 cm high means it fits into almost any small pot or cooking system, streamlining your entire cooking setup.

A core ergonomic feature is the resealable screw-on valve. This makes life incredibly easy, you can disconnect your stove, use the gas with a lantern, and then reconnect the stove again. All without wasting any fuel. This flexibility is a huge plus for tourers and multi-day hikers.

However, you do need to be mindful of its construction. Because the canister is metal and can dent easily, care must be taken during transport to prevent damage. Make sure to always store the canister below 40 °C, especially in hot vehicle interiors, and checking it with soapy water for leaks if you suspect a large dent near the valve or base. And always remember to use the canister in well-ventilated areas for safety.

Performance & Features

Companion Pro Fuel consist of 45/28/26% Butane/Isobutane/Propane mix, which is its most important feature. While it’s slightly Butane-heavy (Butane is cheaper but fails below 0 °C), the high percentage of Propane and Isobutane ensures it keeps firing up even when morning temperatures dip closer to freezing, which is a common scenario in the high country or southern regions.

The resealable screw-on valve (following the EN417 standard) is a fantastic feature. It genuinely allows you to swap between different screw-on appliances, like a compact hiking stove and a small lantern, mid-trip without having to burn off the remaining gas. This is excellent for efficiency.

The 230g size is a great balance, it’s enough fuel for several days of cooking for one or two people, but remains light enough for backpacking. For a heavy-use base camp, the larger 450g option might be better, but the 230g version is ideal for maximizing portability for your Coffee Gear and cooking needs.

Frequently asked questions

Can I use the Companion Pro Fuel cartridge with a regular bayonet-style camp stove?
No, the Companion pro fuel cartridge uses a standard threaded, screw-on valve (compliant with EN417), which is common for hiking and small upright stoves. It is not designed to connect to the push-and-twist bayonet stoves that use the long, cylindrical cartridges. Always match the canister valve type to your stove.
What makes this a "four-season" gas blend, and how does that help in the cold?
The four-season blend includes higher percentages of Propane (26%) and Isobutane (28%). These gases have much lower boiling points than pure Butane, so they maintain higher internal pressure in freezing conditions. This ensures that companion pro fuel butane gas​ continues to vaporise and burn efficiently, unlike pure butane which stops working effectively near 0 °C.
Is it safe to transport the companion pro fuel cartridge in the back of a hot car in summer?
No, you should avoid storing the companion pro fuel cartridge anywhere the temperature exceeds 40 °C, especially not in a closed vehicle on a hot day. Excessive heat can dangerously increase internal pressure. Always store it upright in a cool, well-ventilated space, ideally outside of direct sunlight.
