    I have a RIM PN HDW-34724-001 Model AD0213HF AC Wall Charger Input 100-240v, Output 5v, 1.8A & what I want to know is whether this is a solid state device or a transformer, the former able to remain plugged in while not connected to the phone (does not consume current), the latter needing to be unplugged when not in use (otherwise consumes current)?

    The plastic bag it came in says made in China. The printing on the device says Japan.

    It is a transformer, obviously.

    You cannot get 5V from 110/240 without any transformation

    Then, again, why are you worried regarding current ussage?

    I still would like to know if the charger unattached to any device but plugged into a/c draws any current when not in use...

    You realize that in max consumption, 1.8A with 5V is just 9watts.

    If you want it, on max output (which is not the case when the charger is in the socket while not charging anything) it needs to be connected almost 5 days (and charging) in order to consume whole 1 kwh

    So if it is just plugged in to the wall, but not connected to any device, then the circuit is open and current is 0. Although if you think that it consumes something as the transformer, then even if there is any current "consumption" then it is close to 0
