Most smart phone batteries are 1500-3300mah.

A 3V battery has 50-70mah and at 500mw load has >30mah capacity.

Just exactly HOW much does this remaining >30mah charge your phone ???

This is cute but utterly pointless, it's like using a tortoise to tow a bus.

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?
