BMW USB Charger - Light Stays On all the time

Like many 328i owners, I have kids. Kids with iDevices. So I thought it would be a good idea to remove the cigarette lighter plug behind the center console so that the kids could charge their devices. So I purchased the $25 BMW charger sold on the BMWUSA website.

After plugging it in, I noticed that that the green LED was on, with no ignition or accessory power applied.

I am pretty sure the car has an auto shutoff to preserve the battery if something (like a an overhead light) is left on, but I do not want to count on that. It does the same thing if I move it to the lighter receptacle in the front of the console. Am I overlooking something simple? You would think that the power to these lighter receptacles would be key/button controlled and not applied at all times or that BMW, knowing that it was, would not have an LED in the charger.

It doesn't stay on. I have one plugged into the socket where the ashtray would be and got a little concerned about what appeared to be a permanent power supply. It even stays on if you get out of the car and lock it.

However, it appears it is timed. I made a point of checking the other day. Left the little cubby open, got out of the car, locked it, green light still on. Went for a coffee and then when I came back I looked through the window and the light was off. Unlock the car and it comes on again straight away.
