I should have bought one of these a long time ago.   
      
   I have a Plug-in Prius without a spare tire, and they ship a semi-proprietary   
   tire goop/inflator combination that kills the TPMS sensor.   
      
   I bought a kit with a tube of TPMS-friendly Slime and a 12v inflator. Instead   
   of going to the gas station, asking them to turn on the air (that used to be   
   free) and switch back and forth between the air hose and my hand-held pressure   
   gauge, now I plug the inflator into one of the lighter sockets, attach the   
   hose to the tire stem, turn it on, use the built-in gauge to check inflation,   
   and flip the switch when I get to the pressure I want. Repeat x 4.   
      
   So. Much. Easier.
