No, this inflator does not include a CO2 canister; it's designed to be used with cartridges purchased separately, such as the Rockbros CO2 Canister pack sold on this store. Make sure to pick up compatible cartridges alongside the inflator so you're ready to use it when needed.

As a general guide, one cartridge can inflate a 700C road tyre to around 120 PSI or a 26-inch mountain bike tyre to around 30 PSI, since road tyres need higher pressure but hold less air volume while mountain bike tyres need more volume at lower pressure. If you frequently ride wider gravel or MTB tyres, it's worth carrying a spare cartridge in case one isn't enough to reach your preferred pressure.

It works with both Presta and Schrader valves, so it covers most road, hybrid, and mountain bike setups without needing a separate adapter. This makes it a practical single tool to carry regardless of which bikes in your household you're riding.

The inflator is built from CNC aluminium alloy with a rotatable control for smooth, repeatable inflation, and it comes with a protective sleeve that guards against frost forming on the cartridge during use as well as making it more comfortable to hold. This construction is designed to hold up to repeated roadside use over the life of the product.

CO2 cartridges get very cold during rapid discharge, so it's important to avoid direct skin contact with the cartridge or nozzle while inflating; the inflator's protective sleeve helps with this, but wearing gloves or using a cloth for extra grip is a good habit. Always thread the cartridge in as directed and puncture it slowly and deliberately rather than all at once, to avoid a sudden burst of pressure.
