I also purchased from the same guy a 3.2 volt wall wart. I could have used a single LIPO 123 battery, but I took the easy way and bought the wall wart.
Gosh, I have so many wall warts in my basement, I could've probably found one instead of buying it, but it just so happens that I did a search for wall warts last weekend on another EE project and I don't remember running across a 3.2 volt supply. So I pulled the trigger on this purchase too.
