The Moshi Xync Micro-USB 2.0 Keychain eliminates having to carry an extra cable when you're on the road. It features a tuck-away micro-USB cable and a sliding USB Type-A connector. Attach it to your keyring or bag when not in use, and remove it to connect your micro-USB device to your laptop or USB charger. When you're done, simply retract the USB Type-A connector and tuck away the micro-USB cable. There's also a hidden storage compartment with one Micro SIM and one Nano SIM card slot as well as a SIM eject tool.
