The Easy iPod Media Sharer.

This device allows you to quickly and easily transfer music, video, and pictures from one iPod to another iPod without the use of a computer. It automatically recognizes when you plug in iPods (either Mac or PC formatting) on either end, and it can transfer a three-minute song in five seconds and a 30-minute video in three minutes. The device can also transfer any files when the iPods are set to "disk drive" mode. Its rechargeable battery provides up to 1 1/2 hours of operation during transfers, and includes an AC adapter that recharges the device in four hours; iPods are recharged while connected. Songs transferred with digital rights management (DRM) formatting require appropriate iTunes password and authorization. 3/4" H x 2 1/4" W x 3 1/2" D. (2 oz.)
