This powered cup holder with a 8 pin connector plugs into a compatible controller and offers cooling + LED lighting at a touch. This cup also features a "lock" button to prevent accidental presses. Cup needs an extra 3-5 inches of depth into chair armrest or table to allow heat sink to "breathe" and provide proper ventilation. We recommend waterproofing seal upon installation to protect the lower parts from condensation and spills.
