Ever since getting my CR-48, I have been in search of a second power supply. While the CR-48's battery life is simply outstanding, I still find my self carrying the power supply around, primarily between work and home. I was able to get a nice laptop sleeve for the CR-48 so carrying the power supply is an inconvenience. After searching today, I finally found an answer. According to the post I found, the Chrome Ninja's have recommended the Lenmar LAC50, a universal notebook power adapter that can be set to 19V/2A and works great!
