Like the MacBook Pro external battery/charger that was announced last month, QuickerTek has rolled out the same kit for the MacBook. It still costs an egregious amount of money at $450 and you still have to get your power brick modified for $25 by sending it in or shelling out an extra $100 for a modified brick. I need the extra 6-10 hours of juice, but I think I’ll pass and get another laptop like Devin suggests.
