I just bought a new dust-buster it's a nice little machine. It's got good sucking power, and does the job it was purchased to do. My only gripe is the charger stays on even when the d.buster is fully charged. I'm trying to reduce the amount of energy we consume here, so I've taken to unplugging the unit when I'm not charging it.
I had to take the picture in night mode, so you could tell the little red light was on.Charger pulling power when charged

Almost all adapters use power when they are plugged in, even when what they are plugged into are not connected.
I wish there were a device you could put between the outlet and the charger to shut it off when the item was no longer pulling power, or there was nothing attached.
I wonder how that would work electronically speaking? The device would have to be capable of sensing how full the battery was. If my regular battery charger can do it, why not though?
Unfortunately measuring power consumes power. A simple mechanical switch could be added to most power adapters quite easily though - when the device being charged is attached, the switch would be thrown to connect the circuit and start the flow of electricity. When it is removed, the circuit would break.
Honestly I'm surprised that this isn't already in existence.
