Here's a recent photo of the 2.0 Console installed on my 2018 Model 3. The stock inductive charger pad still looks new, but I have it covered with a black silicone rubber anti-skid cover. Seems to better match the older interior.

Before I installed this used 2.0 Center Console, I tested the inductive charger to make sure it was still in working order. I was also interested to find out how much current it draws when not being used to charge a phone. My Fluke multimeter showed it, on average, uses only 0.010 amperes. Most of the time, it only draws 0.002 amperes, but every few moments, it pulses the coils to see if a phone has been placed on the charging pad. That pulse increases the current to about 0.045 amperes. This kind of current draw is not significant when driving the car any distance.
The inductive charger is powered by the same switched 12V power feed as the front and rear USB modules. So when parked, the power to these usually times out after a few minutes, unless Sentry Mode is enabled.
