Hello, just wondering, I want to buy an 'adapter', such as from 120VAC to 9VDC 2A. I want to have one that has the lowest standby power from the wall.
So for example if the load on the output is zero, then I would expect the adapter to be loading the 120V side with little to nothing. However I understand in most adapters the 120VAC goes immediately into a transformer, so that's quite a load already. I seen some adapters marked an "input: 120VAC, 11W" so I assume that's even with no load on the output.
I seen also some switching power supply adapters, but I'm not sure what the standby is like on those, are they less? Any recommendations?
Thanks.
