Dual button design allows for intuitive switching between 5 preset modes. Choose based on your needs and forget about complications. Accurate to 1.5 psi, the digitized pressure measurement stops inflation at the preset value, effectively preventing over-inflation. The unit can be changed between psi and bar. This 2500mAh battery can be fully charged in 3.5 hours with the included USB-C cable. It can fill a flat car tire in 8.5 minutes or a bicycle tire in just 129 seconds. The design allows for natural airflow through the core. Combined with the internal cooling fans, heat dissipation is accelerated and inflation efficiency is guaranteed. The integrated LED light comes in handy when you are in dark places, whether on a night trip or in an underground garage. The outer TPU case makes it slip-proof and shock-absorbing, and prevents the compressor from being damaged in accidental collisions, to better handle harsh environments.
