The Airboy CO2 combines a mini pump and a CO2 tyre inflator in one slim, short, lightweight (142g) package.You can inflate tyres the good old-fashioned – if a little tiring – way or you can screw a CO2 canister to the opposite side of the valve head and use the dial at the end of the pump to control the airflow.
This function works well, and combining the two means less space is taken up in your pack. But the lack of a locking lever to clamp the pump head in place on the valve makes it tricky to get a proper seal. The pump’s volume isn’t massive either, so big tyres take a while to inflate.
