This is exactly the problem we had with the Bialetti. We placed it on the griddle and noticed that the heat mainly goes past the Bialetti. The grill plate is also not very good for grilling (charred on the outside and raw on the inside). So my recommendation: save the money and use one of those aluminium supports for fondue caquelons so that the Bialetti doesn't fall off.

It is compatible for both modes. It is the optional regulator that makes the difference.

You always need a pressure reduction between the storage tank and the consumer so that you have a constant pressure on the consumer side. Look here: https://www.campingaz.com/CH/t-CH_Umgang_mit_Druckreglern.aspx You need the regulator at the bottom right (50 mbar). Galaxus, Migros do it, Coop Bau und Hobby, Jumbo ...

I own a 30iger, as I run it with a caravan, there are also 50igers

Hello, unfortunately I can't help you because I haven't used the cup yet.

The bottle does not matter, the adapter on the hose must be compatible with the bottle.....

I am not sure if this works : Weber hose with pressure reducer Campingaz pressure regulator CGS

Yes, the grill attachments are included.

Yes, it still needs a 50 Mbar pressure regulator: Campingaz pressure regulator 50 mbar

No, unfortunately this does not work on the caravan.

No, this is not suitable for use with cartridges. You need either the Campingaz R907 bottle or a standard 5kg or 11kg gas bottle.

Hello! Basically, all gas bottles with a standard connection (https://www.vitogaz.ch/gas-in-flaschen/sortiment) fit. When you buy a gas bottle for the first time, you have to pay a deposit (approx. 50-60 CHF). You also need a pressure regulator with hose (https://www.campingaz.com/CH/t-CH_Umgang_mit_Druckreglern.aspx), which is not included in the delivery. This gas cooker is extremely powerful - you will enjoy it.
