besides using for an old charger for the smart phones...why do I have a 12V in my new car? And what will I use it for in the future?

besides using for an old charger for the smart phones...why do I have a 12V in my new car? And what will I use it for in the future?
thanks for the info. Kind of thought these were the uses. I don't plan on camping or living in my X so I still can't see the use for me specifically.12V is very useful:
.Portable inflator & and other power tools (12V jack, 12V impact wrench for a flat tire on the road)
.Portable Stereo: Your A/C can continue to work but your built-in stereo will timeout so you need Sentry Mode to run your 12V portable one.
.Portable TV
.Portable kettle
.Portable stove
.Portable refrigerator...

Does having Sentry Mode on constantly, aside from the aggressive phantom drain, cause damage to either the 12 v or the car's battery pack?
am I understanding you correctly, that the car mobility is "driven" by the batteries under the seats and anything else like dash lites, wipers radio is powered by the 12V..that seems hard to believeI'll second everyone else's statements. The entire car runs off of 12V. Pretty much the only thing I think that doesn't are the wheels and possibly heater core.
The 12V accessory outlet is for all sorts of items. The USB ports are slow charging, for example, if you want faster, you need to use a aftermarket 12V USB charger.

ok then! First thanks for quick response. Where is this 'fella' stored..I am assuming it is what is normally charging a ICE ..that large? and how long is the warranty?Correct!
400V Main battery powers:
HVAC,
Heater
Drive Units
12V powers the rest:
Lights
Audio
Screens
wipers
Powered brakes (without power, you can still mechanically brake but harder)
Powered steering (without power, you can still mechanically steer but harder)
Battery Management System (no 12V means no way to charge the main battery)
Small motors/solenoids/electronic latches: for seats, windows, doors...
Accessories...
..that large?...
...stored..
...warranty..
thanx very helpfulModel X's 12V battery doesn't look that big. It certainly looks smaller than my former Ford Escort's.
The 12V battery is located under and between your 2 windshield wipers (after you take out the frunk tub and its HEPA filter):

12V battery is considered a consumable item just like your tires or your windshield fluid. However, Tesla has been covering it under the warranty in the past but I don't know whether it will continue to do so in the future.
The reason the Tesla 12volt is a bit smaller than ICE 12volt is ICE have the HUGE demand of cranking the engine to start, once running, the accessories in an ICE run off the alternator which recharges the battery too. In a BEV there is an inverter that steps voltage down from the big battery to power everything when driving and recharge the 12volt as needed. In a Tesla though when the car is parked it really is much less asleep than other cars so the 12volt drain is much higher when parked.ok then! First thanks for quick response.

Because???The reason the Tesla 12volt is a bit smaller than ICE 12volt is ICE have the HUGE demand of cranking the engine to start, once running, the accessories in an ICE run off the alternator which recharges the battery too.

Because???
The car has a lot of regular car parts that come from standard automotive suppliers, like for window motors, windshield wiper motors, cigarette lighter sockets, etc. and the auto suppliers don't make versions of those common car parts that run on 400V DC, so Tesla does need to supply a 12V system that can run the regular little accessories like that.am I understanding you correctly, that the car mobility is "driven" by the batteries under the seats and anything else like dash lites, wipers radio is powered by the 12V..that seems hard to believe
Conventional cars do not need to drain its 12V while parking because they don't need to keep a computer alive. So, it has less vampire drain.
On the other hand, Tesla believes in electronics and it keeps its computers alive even when it's "asleep" so its battery drain is much more than conventional cars'.
Sentry Mode uses a lot of 12V power. Your car keeps monitoring and keeps communicating to its mothership looking for a new update, reporting its position and status... Even in its deep sleep, the computer still monitors the temperature of your main battery and automatically turn on heater / HVAC to keep the main battery happy.... All these do drain the 12V battery.
