ONEUP EDC PUMP - Review of a pump with hidden features

The "100cc EDC Pump" is an high capacity bike pump from OneUp Components. Designed to carry their compact EDC multitool and a spare CO2 cartridge inside! its body. The fast on valve head can be removed to be used as a CO2 inflator, and the cap can be removed to store spare CO2 cartridges and more inside. I decided to test how well the pump worked and to see if the internal storage could be useful even without purchasing the EDC multitool.
