C02 Gas Cartridges

A Powerlet cartridge, commonly referred to as a CO2 charger, is a small disposable metal container holding 8–12 grams (0.28–0.42 oz) of compressed CO2 and often a small quantity of oil, used as a power source for certain air guns, airsoft guns, paintball guns, and for quick inflation of various devices, such as a personal flotation device.
