Bring this smart CO2 pump and be prepared for anything. This CO2 pump comes with a clever trick in the holder, allowing you to store a cartridge without puncturing it, even when the head is screwed on. When you need the pump, simply unscrew the head, flip the cartridge around, screw the head back on, and you're ready to go. In this configuration, the holder acts as cold protection.

The pump head inflates by pressing it down against the valve. Note that there should be a maximum of 4-6.5mm of free thread when the cartridge is in the holder; otherwise, the pump head may puncture the CO2 cartridge during storage.
