This was my first thought for making a stand. I'm just trying to find the right components so it actually holds the charger in place like the stands you can buy, plus I want it to be smooth and all the pieces matching (going to be tough as I don't really want to break up and of my sets). Maybe I could adapt my Lego R2 D2 to become a charging stand somehow as that already sits on my bedside table.
I want to use all matching pieces too, but then they would have been REALLY mad.
The round piece holding the AW charger is from a fan/turbine housing from a TMNT set. I did cut a small notch so it could lay flush.
