No problem! Set my power supply to 12V and hook it up to my car charger. 
Does anyone else use their power supply for anything like that?

I have one of those rechargeable "wand" massagers that I bought back in the 1980s. When the nicads finally died, I rewired the charging plug so it feeds the motor directly, and run it off a bench supply. It now works even better, because I can vary the speed
I don't have an adjustable supply yet. Need workshop first.
I have a degree in chemistry. I'm never going to be happy unless I have a few instruments that I can use to recreate lab conditions. A variable power supply is a must! 
BTW, the one I got is a "cheap" ~$40 one off ebay. But it works beautifully and having that for random needs is invaluable.

Be careful and don't provide us with too much information.

Hey @Tweedius,
I saw your signature says you are from Madison WI... I attended school there... it's a very nice town.
"wand" massager == one of these.
