Lighter: In general, CO2 inflators are lighter than a good hand pump. Faster inflation time: CO2 inflators will air up your tire in a minute, which is much faster than a hand pump can achieve.

CO2 tanks are compact and yield a lot of shots for their size and weight compared to compressed air. CO2 does have disadvantages that can impact your game.
