Will probably be the adapter supplied. Primus has different versions of the same cooker for different countries/regions. For example, a different adapter is included for the Nordic countries, etc. But it takes some research on the manufacturer's website to find out what is included where and then to find it on Galaxus: https://primusequipment.com/de/pages/primus-adapter-guide However, if the manufacturer number 350120 is correct for the "Piezo", then no adapter would be included here. The other one has a manufacturer number that I can't identify. Maybe it's the one from Bergfreunde.ch... The price (differences) at Galaxus/Digitec are not very meaningful, as they are usually calculated automatically and due to different prices in the selection of suppliers, a "better" model can sometimes be cheaper.

The Primus Tupike Stove comes with a grill plate and a packing bag for the grill plate. A special bag for the entire cooker is not mentioned.

The Primus Tupike cooker can be used with normal large camping gas cylinders, but an adapter is required. This adapter is usually purchased separately as it is not always supplied. The instruction manual may refer to use with disposable cartridges, but it is possible to use the cooker with larger gas cylinders if the correct adaptor is provided. It is important to ensure that the adapter is connected correctly to ensure safe use. If you have problems changing the adapter, it may be helpful to check the instructions again or contact the manufacturer.

It's obvious 😂Take the width from the specifications and the depth from the packing dimensions. What favre.ch says about dimensions is unfortunately a fact 🤷

You need an adapter for this, which galaxus unfortunately does not carry. But it is available from Transa

I didn't have one. That was in October 23.

The cooker has been proving its worth for a long time on our travels (9 weeks in Africa). Important: always let it dry well after cleaning, otherwise it will corrode). The piezo has failed from time to time, sometimes on one side, sometimes on the other. This is not really a problem, but it is still a small defect. Otherwise highly recommended.

It is permanently mounted. Depending on the gas bottle, you may need a different adapter. https://youtu.be/tOfHeLFPBwA

The difference is that a DIN combination adapter is included in the Tupike cooker.
