Charge a Walkie Talkie Watch on a phone line…(in a hurricane)

Redbluefire posted some photos on Flickr of his experiences riding out hurricane Wilma – his power went out and with the phones only working he used the phone line to charge up the Walkie Talkie watch gadgets “…the two lines in the phone that supply power, Red was positive, but to my suprise the ground was not black, but GREEN! After that, it was all a matter of opening the watch, checking the pinout, and twisting the wires to hold onto the jack inside. I need to communicate, and sometimes a laptop just isnt worth wasting for idle communication.” Link.
