FastMac announced a new line of Mac notebook chargers today. FastMac found a work around for Apple not licensing the MagSafe chargers. TruePower U-Charge allows you to charge your notebook's batteries externally. Note that this does not power the Mac, it only charges batteries.
This charger will charge iBook G3/G4 12", PowerBook, MacBook, and MacBook Pro batteries without skipping a beat. FastMac also has plans for a 14.4V charger that would charge batteries for the clamshell iBook, iBook G4 14", and Ti PowerBook 15".
The TruePower U-Charge comes in 2 different colors (black and white) to match your machine better. The prices for these chargers start at $69.95. You can purchase the U-Charge on the FastMac website.
