Hypermac got the Juice like Tupac!! I need to get me this to power my laptops.
"If you do a lot of on the field work with your mac, you already know how inadequate the battery life can be. SanHo's HyperMac batteries change that with 4 external battery options that will power any MacBook (with MagSafe) for up to 32 hours. The batteries also have a USB port for powering and charging any USB device"
