Campingaz CV 300 Plus Gas Cartridge Review

Overview

The Campingaz CV 300 Plus is a 240g valve-type gas cartridge filled with an 80/20 butane/propane blend, designed exclusively for use with Campingaz’s proprietary Easy Clic Plus appliances. It’s aimed squarely at recreational campers, festival-goers, and casual hikers in Europe — particularly those already invested in the Campingaz ecosystem. If you’re a thru-hiker or ultralight backpacker shopping for the most capable or lightest fuel option, you’ll want to read the caveats below before committing.

Performance

Gas Mix and Temperature Range

The 80/20 butane/propane split is where this cartridge has the most to answer for. Butane has a boiling point of −1°C, just below the freezing point of water, which means it struggles to vaporise in cold conditions. The 20% propane content does push performance further than a pure-butane cartridge — the CV 300 Plus can function down to approximately −5°C — but that’s a fairly narrow margin for anyone camping in shoulder seasons or at altitude.

Compare this to the isobutane/propane blends used by most dedicated backpacking canisters. If you want a high-performing canister and plan to camp at altitude or in winter, you need as high a proportion of propane as possible, blended with isobutane rather than butane. Due to their lower boiling points, propane and isobutane vaporise more quickly at lower temperatures — but if you’re camping in sub-zero weather, butane may not vaporise at all, reducing the flow of gas to the burner head. In practice, once you’re reliably below 0°C, the CV 300 Plus will start losing pressure noticeably. For three-season, temperate-climate camping it’s fine. For winter mountaineering or high-altitude use, it isn’t the right tool.

The Easy Clic Plus Valve

This is genuinely one of the better things about this cartridge. The Easy Clic Plus connection allows the fixing of a valve cartridge safely on a stove with a simple 45° rotation. The unique self-sealing safety valve allows secure and tight closure, and the cartridge can be removed and re-attached even when it is not yet empty — a meaningful advantage if you’re running one cartridge across multiple devices at camp, or if you need to pack away mid-cook in a hurry. That’s a real-world convenience that standard Lindal-valve canisters don’t offer. The cartridge also has an unlimited shelf life when stored properly.

Compatibility: The Big Catch

Here’s the problem for anyone shopping from the broader backpacking world: if relying on a gas stove, you’ll typically be looking for an EN417 canister with a Lindal valve, which is compatible with the vast majority of backpacking gas stoves and is found across the world. The Campingaz Easy Clic Plus system is a different standard entirely. An MSR Pocket Rocket 2 stove, for example, cannot connect directly to a CV canister. You can find third-party adapters, but that adds complexity, cost, and a small point of failure to your kit. If you’re committed to the Campingaz stove ecosystem — a Twister Plus, Bivvy, or similar — this is a non-issue. If you’re not, it’s a deal-breaker.

Weight Efficiency

The numbers here aren’t flattering for ultralight-focused hikers. At 410g total with 240g of gas, the empty canister shell weighs roughly 170g. A comparable 230g MSR IsoPro isobutane canister weighs around 340g total, with an empty shell of approximately 110g. That’s 60g of extra canister weight you’re carrying for a nearly identical gas payload — and the CV 300 Plus’s gas mix is less cold-weather capable to boot. Campingaz cartridges are 100% made and quality controlled in their own factory in Lyon, France, and the build quality is solid, but the valve mechanism does add real mass.

Availability

The bright blue Campingaz canisters are especially common in France, but also found across Europe (mostly northern), the UK, and Australia.

For European trail towns and camping shops, this is often the easiest canister to source. If you’re touring in France or walking a long-distance European route, that availability matters more than the weight penalty.

Pros & Cons

Pros

• Resealable Easy Clic Plus valve is genuinely convenient — swap between devices without losing gas
• Secure, audible click connection removes guesswork at setup
• Reliable 3-season performance down to around −5°C
• Consistent supply in European camping and outdoor shops
• Unlimited shelf life when stored correctly
• Manufactured and quality-controlled in Europe (Lyon, France)

Cons

• 80/20 butane/propane mix underperforms isobutane/propane blends in cold or high-altitude conditions
• Proprietary valve locks you into the Campingaz ecosystem — incompatible with the vast majority of backpacking stoves without an adapter
• Heavy empty canister shell (~170g) penalises ultralight packers
• Meaningfully more expensive per gram of gas than standard isobutane canisters in many markets
• Not widely available outside Europe and Australia

Who Should Buy This

The CV 300 Plus makes most sense for campers and light hikers already using a Campingaz Easy Clic Plus stove — particularly in the UK or continental Europe where these canisters are easy to find in supermarkets and hardware shops. It’s also a smart pick if you’re running multiple Campingaz appliances (stove, lantern, grill) from a single cartridge, since the resealable valve earns its keep in that scenario. It’s not a good match for thru-hikers optimising for base weight, cold-weather mountaineers, or anyone outside the Campingaz ecosystem.

Verdict

The CV 300 Plus does exactly what it says: it delivers reliable, clean-burning fuel for three-season camping in a convenient resealable package, and it’s easy to find across Europe. But it carries a real weight penalty versus standard isobutane canisters, its 80/20 butane/propane mix is behind the curve for cold-weather performance, and the proprietary valve is a compatibility wall for anyone not already in the Campingaz world. Solid within its niche — just make sure that niche is yours before you buy in.
