A portable method of dispensing your kegs on the go. No longer do you have to lug around your heavy, unbalanced CO2 tank. This hand held CO2 unit pushes out your beer using small 16 gram CO2 cartridges. This unit works with ball lock kegs. Uses 2-5 16g cartridges to push 5 gallons of beer. It will not work for carbonating your beer because of the small amount of CO2 in each cartridge.
