The flipSYNK USB cables are clever little keychain-sized multi-USB adapters (this one’s got a micro- and mini-USB tip) that snap together to form a small, easily-pocketed, snag- and tangle-proof fob. Some users have reported difficulty in getting the cables to work as both a charge- and data-conduit (I’ve had this problem with retractable USB cables before), but others seem to get along fine. I’ve ordered one for my Nexus S, but I’ll be returning it if I can’t use it for data as well as juice. Caveat emptor.
