Unconnected wall wart power consumption

[QUOTE="DaveE, post: 6452021, member: 644223"] There are existing energy efficiency standards for these things and more on the way. One little wall wart may not seem significant, but what if everyone in your country has 10-20 of them plugged in all the time. That adds up to lots of wasted energy if they are still old school designs. Here's [URL='https://www.cui.com/efficiency-standards']a summary from a PS manufacturer[/URL]. Since no one pays me for this anymore, I'm not really going to read the details, you can. But it looks like a standby power consumption limit of 100mW is a common requirement. The days of 50/60Hz transformers are practically history. [/QUOTE]
