• SCHRADER & PRESTA VALVE: Schrader/Presta Valve can be used, no need to replace the air nozzle
• METAL ANTIFREEZE SHELL: The rapidly released carbon dioxide gas will form a frost protection cover on the inflatable surface, which can effectively prevent finger frostbite
• COMPACT AND PORTABLE: A small and portable air pump that can be held with one hand
• PRECISE PRESSURE GAUGE: Real-time pressure measurement to prevent over-inflation
• ROTATE TO CONTROL AIR OUTPUT: The air volume can be rotated to control the amount of air, and the inflation can be stopped during the inflation process. Note: The gas cylinder must be used once and cannot be used twice to avoid danger
