Five sizes are listed: 666 g, 2 kg, 4.33 kg, 5 kg and 10 kg. None outranks the others. Throughput decides -- how much passes over the bench in a week, and what a mid-service unit change costs in time.
The 666 g charger covers ordinary volume on compatible dispensing kit: a cafe, a bar working through a limited number of drinks, a pastry section plating to order. Minimal storage, and a spare is no burden.
Two kilograms is one listed format among several, not a universal answer. Compare the manufacturer documentation for the exact item, including its package and approved equipment. A matching capacity on another brand does not prove equivalence. Record what is confirmed and identify any specification that still needs clarification.
The 4.33 kg unit targets one specific cost: changing a smaller charger more than once per service. It buys back that interruption.
Professional N2O tanks at 5 kg and 10 kg require a compatible regulator and planned storage. They are worth it where throughput is heavy and consistent, and not otherwise.
Verify any size against the current manufacturer instructions for your regulator or siphon. Send the model across and we will confirm the fit before the order is set.
