The Campingaz CV 470 Plus is the larger resealable valve gas cartridge for Campingaz stoves, lanterns and grills with the Easy Clic or Easy Clic Plus connection. It contains a high-performance butane and propane mix, which keeps appliances working better in cool weather than plain butane, and its bigger capacity gives roughly twice the run time of a CV 300 Plus, so you change cartridges less often on a longer trip. Push the appliance onto the cartridge and turn until it clicks for a secure, tight connection. The self-sealing safety valve lets you remove and refit the cartridge even when it is not empty, which is handy if you use more than one appliance or want to pack the cartridge separately.
