that's great... so you charge your led throwie with that?

seriously neat design, but lacking somewhat in practicality.
now, replacing the button cells with a slim li-po battery, and step-up IC... you could probably get a solid 911 phonecall in with the emergency charge. or actually get a fair bit of juice into your mp3 player.

Besides being a neat party trick to say "watch this, it's charging my cell phone, see the charging icon?" ; what is the purpose behind the design? What purpose did you design this for?

Thanks for write to me.
With this lithium battery you can charge the phone about 5minutes,I will replace them with rechargeable batteries CR2032.
I am electronic desigher and i love to experiment and build it stuff.
