via Brew Hardware.  Unlike handheld portable CO2 chargers, this mini regulator has an adjustable pressure knob.  Accepts either 12 or 16 gram cartridges.  The low pressure side of this regulator is a male flare that should thread into your ball lock or pin lock QD.  16 gram cartridges are available on the right side of the product page.  This regulator is just $29.99.  Compare to the similar (but not the same) Leland Mini Regulator.

Use for portable dispensing of your keg of homebrew.
