Buy the Weber conversion set. It works with it.

Unfortunately we can't answer this question, because we couldn't test this in such a form. It is best to ask the manufacturer directly: https://www.primusequipment.com/de/de-de/kundenservice/kontakt

Yep

We never burn both burners at full power. Since we don't carry this cooker in a backpack but in the car, we don't use cartridges: However, with a Campinggaz R904 1.8 kg butane gas bottle (attention: adapter needed) it lasts for two to three weeks with daily use. So it could be that the 100g cartridge is already enough for 1h (assuming that we heat for approx. 1h per day for 14-21 days). To know exactly, you would have to do the math.

Hello We also use the camper on a wooden plate, this does not get hot under the stove. Don't know how it is when the oven would run for 2-3 hours. But I don't think it's a problem.

You can connect practically anything. It's just that you have to buy all the adapters separately. There are 5 versions of the adapters

Can confirm that it only works with a valve cartridge adapter, as the thread is missing on Campinggaz cartridges. However, the adapter at Transa is not from Primus, so first confirm that it works with the Kinjia. By the way: The Kinjia is great. We have been cooking with it as a family of 5 for a few weeks.

It is best to contact the customer service, unfortunately the product does not give any information about the connections.

The sheet metal base and the additional sheet metal insert shield the heat development well at the bottom. In this respect, there are no temperatures at the bottom that could set something on fire. The cooker also has rubber feet. I consider a wooden base to be harmless. I would be careful with plastic materials (plastic, plastic resin coating...) if used for a long time. Otherwise, it's better to put a sufficiently large board underneath. Incidentally, the cooker is really great.
