All common 60L/400-425g cylinders with the standard thread type "TR 21x4" are compatible.

With a full CO₂ cylinder you can fill the in the bottle integrated carboniser about 10 times. Up to 10 bottles of sparkling water, i.e. 6 liters, can be produced with a full carboniser. In total, this results in 60 liters of sparkling water.

As strong as you like it! We recommend 1-3 carbonation cycles. A carbonation cycle works as follows: You press the carboniser button until you hear a hissing sound. Now shake the bottle for a few seconds and if you want, you can then start with another carbonation cycle.

Your spark bottle weighs 460g in total. The weight of the carboniser is 250g, which is more or less equal to the weight of a smartphone. Since bottleplus is made of aluminum, a light metal, it's only about 150g heavier than "normal" stainless steel bottles of similar sizes. still bottle weighs 260g in total.

No, you do not have to connect the refilling station to electricity, it works without.

If you listen carefully, you can hear the sound of the CO₂ flowing. As soon as the noise disappears, the carboniser is full. Alternatively, you can also count to 5 or 6.

Generally yes, although foam formation is to be expected. However, a representative series of tests on our end is still pending, which is why we cannot make any promises at this point. However, the bottles are designed in such a way that the sealing rings can be easily removed and thus, like the rest of the bottle, easily cleaned.

You can not clean the carboniser (unscrewable adapter at the base of the bottle) in the dishwasher. The body of the bottle is unproblematic with regard to the inner coating, however, representative tests are still pending for the outer coating. Thanks to the large bottle opening on the bottom, you can easily clean the bottle by hand anyway.

According to official regulations, CO₂ cartridges/tanks are listed as prohibited items in both hand baggage and checked baggage. That's why you're unfortunately not allowed to take bottleplus with you when you travel by plane.

The development of bottleplus has been completed, as well as the setup for mass production. The next step will be the certification of the product.
