What is Portable CO2 Cartridge Inflator?

The portable CO2 cartridge inflator is a small cylinder that compresses carbon dioxide and is used to inflate tires, which are then delivered to the tires through valve heads.

When inflating road bicycle tires, portable CO2 cartridge inflator is usually sufficient to re inflate the tires to the required pressure, and may even over inflate, requiring appropriate deflation.

For larger gravel bicycle tires, a 25g carbon dioxide ink cartridge is generally required to achieve sufficient pressure for re inflation and reinstallation of tubeless tires, avoiding getting stuck due to insufficient pressure.

It may also be used in emergency situations where small inflatable devices need to be quickly inflated, such as small inflatable toys.

When using the portable CO2 cartridge inflator on tubeless tires, the freezing effect of compressed gas may cause the sealant to freeze into a solid. Therefore, it is best to rotate the valve to the highest point for inflation, allowing the liquid sealant to be discharged to the bottom and away from the cold airflow.
