Unlike the cheaper charger kits made from plastic this little charger kit is made from machined anodised aluminium.
The Premium Regulated Charger is very compact but is just large enough to house a very small regulator.

Simply screw on the MFL threaded disconnect, attach to your keg, and set the dispense pressure.

The Premium Regulator CO2 Charger does not come with CO2 16g cartridge you will need to purchase these separately.

New improved model, this is the silver/chrome one as shown in the first three photos.
