The connection of a small gas cartridge is not intended for the Campingaz 400 S, as this cooker is designed for operation with a large gas cylinder (e.g. R907 or 5 kg). The official specifications and product features do not show a connection for small cartridges such as CV300 or CV470.

If you are looking for a cooker with a cartridge connection, you should choose a model with a suitable cartridge connection. This is not possible for the 400 S.
