Tesla MODEL S 2012 Owner's Manual page 21

Low Voltage Power Socket
Your Model S has a power socket located on the front of
the center console. Power is available whenever the
instrument panel and touchscreen are on.
The low voltage power socket is suitable for accessories
requiring up to 11A continuous draw (15A peak) or a
maximum of 150 continuous watts (180 watts peak).
NOTE: Power is available whenever the vehicle is
considered "awake" The vehicle may be awake for many
reasons. For example, when using features such as
Summon, or when features such as Preconditioning,
Cabin Overheat Protection, Keep Climate On, Dog Mode,
Camp Mode, Sentry Mode, etc. are enabled. The vehicle
is also awake whenever the low voltage battery is being
charged or is in use, during HV charging, when the
vehicle is communicating with the mobile app, etc.
Leaving an accessory plugged in does not deplete the
low voltage battery.
NOTE: In situations where Model S is unable to detect
the key fob (low battery, interference, etc.), place it
immediately below the low voltage power socket where
Model S can best detect it.
WARNING: The power socket and an accessory's
connector can become hot.
