Induction Cup Holders

 To avoid the hassle of finding a free power socket and messing around with wires.

I've seen heated travel mugs. I'm sure most of us have. Every one I've seen plugs into a cigarette lighter. I already have a lot of accessories that demand my available plug-in space, so these cups are not an option for me. (and, in case anybody wants to point this out, I already use a 4-socket adaptor, any more and I'll overload the outlet).

So I was thinking (scary thought, I know) why not put an electromagnetic induction charger in the base of cupholders? Simply put in a compatible cup, and voila! Heated cups without the hassle of wires.

       I would like to learn more about induction charging, but alas there is no wikipedia link in this idea. :(
  

       Electric heaters draw quite a bit of current. Would the induction charger be able to keep up with the power demand?
  

       Pastry, just because I detest wires.

       I have a Sonicare toothbrush that charges like this. I just set the toothbrush into the charging base and it charges, no connecting wires or plugs needed.
