There are five sizes and none of them is the good one. It depends on how much you get through and how much it annoys you to change a unit in the middle of a busy night.
The 666 g charger is the little one. Good for a cafe, a bar doing a few drinks an evening, or a pastry bench working order by order on kit that fits it. It goes anywhere and a spare takes up nothing.
A 2 kg listing needs the same careful identification as any other size. Record the full name, package information and manufacturer-approved equipment details. Capacity alone does not establish whether an item is suitable for a particular setup. Confirm the current specification rather than relying on a general impression that one size is the usual choice.
The 4.33 kg one exists because some places change a smaller charger twice in a service. If that is what keeps happening, this is the fix.
The 5 kg and 10 kg tanks are a step up. They need a regulator that fits and somewhere proper to keep them, and they only pay off if you really are getting through that much.
Whatever you go for, check it against the current manufacturer instructions for your regulator or siphon. Send us what you have and we will look before you order anything.
