Whip cream chargers, also known as whipped cream chargers or N2O chargers, are small, cylindrical canisters filled with nitrous oxide (N2O) gas. They are used primarily in the culinary world to create whipped cream quickly and efficiently. When attached to a whipped cream dispenser, the charger releases the nitrous oxide, which mixes with the cream inside the dispenser. The gas dissolves into the cream, creating a light, fluffy texture as it expands when the dispenser's nozzle is pressed.
