N2O -- nitrous oxide, sometimes called laughing gas -- comes to a kitchen either as a cream charger or as a professional tank. Chemically it is the same gas. Practically the two are different tools.
A cream charger is a sealed, bench-sized unit at 666 g, 2 kg or 4.33 kg. It attaches to compatible dispensing equipment, gets used through, and gets swapped. Storage is straightforward and keeping a spare is no trouble.
A professional N2O tank at 5 kg or 10 kg is a cylinder. It holds considerably more, it requires a compatible regulator, and it needs a proper place to stand. What it buys is uninterrupted service: no unit change halfway through a busy evening.
Capacity does not settle the comparison by itself. The exact product, approved equipment and storage requirements still need checking. Compare complete listings rather than treating every cylinder above a certain size as the same format. A product should remain within its labelled intended purpose regardless of how much it contains.
The compliance position is identical for both. Supplied for lawful culinary and food-service use with equipment specified as compatible in current manufacturer instructions, within the applicable regulations. Inspect before use. Never run damaged, altered or wrongly connected equipment. Follow the manufacturer on handling, ventilation, storage and disposal.
Unsure which format fits? Send the regulator or siphon you already run and we will check it against the listing first.
