 Portable Keg CO2 Injector Review

I purchased one of these portable CO2 cartridge-based ball lock keg injectors about a year and a half ago, and it has been one of the best purchases that I have ever made. Instead of having to lug around my 10 pound CO2 tank to a party, I just ramp up the keg with CO2 from the tank. When the pressure drops too low to push, I connect this device, and one CO2 cartridge is enough to empty out the remainder of the keg. It is small enough to fit in my pocket and super easy to use, just make sure that you follow the directions properly or else you can blow your ball lock/pin lock gas valve. So far I have used it on about 5 different occasions and it has never let me down. It even held pressure between uses.


If you are interested in purchasing one, you can find them here at a great price:

    It is always such a pain to lug around a CO2 tank when I bring a keg to an event. I will be sure to have to check this out. Are the CO2 cartridges reasonably priced? I would be nice to always have a few on hand.

      They are very reasonably priced. You can usually pick them up for about $1.50 each.
