So presumably, since they're the same type of power supply, you leave your mobile phone and other chargers on all the time as well?
My current phones are powered either by USB cables or PoE, so I guess yes, I do leave them plugged in.
Even if not the either of the above, due to circuitry inside, most modern chargers draw no or negligible power when not charging a device, so yes I do leave most things on all the time.
Also in my defence, anything that gets left plugged in and turned on is stuff that has a 99.9% chance of getting used daily. Anything else tends to get unplugged after use in order to reduce cable spaghetti.
