Can I leave an AC adapter plugged in 24/7 as long as it's not charging anything?

I know that power is constantly supplied to the thing, but of I just have the adapter itself plugged in with the car off, nothing charging off of it, will that drain the battery too?

Depends on the adapter.
An inverter does not draw if it is turned off, but does any time it is turned on, with or without a load, since it is producing heat energy if not DC energy. If it has no on/off switch it is drawing when plugged in.
A simple 12VDC/5VDC doesn't. That is just a resistor on 1 leg of the circuit. A more complicated circuit would draw.

ooohhhhh my bad. Missed the "AC" adapter. When I was truck driving, I always unplugged mine because it did drain the battery on my semi after a few days because it is constantly converting DC power into AC power at the ready, it does not necessarily "store" that power and hold it like a battery would. So yes, I would definently unplug it while the vehicle is not running.
