Compact, always-ready, and tangle-free, Griffin's retractable USB cable has all the charge/sync bases covered, including Micro-USB devices and Apple's Lightning connector devices.
In your bag, pack, or pocket, it measures less than 2 inches wide by half an inch thick, and just under 4 inches from connector tip to connector tip. But pull out the spring-loaded cable and you have a full 27 inches of tangle-banishing USB connection, with a standard Type A USB connector at one end for your computer, and a compact Micro-USB connector at the other end for smartphones and cameras and all kinds of devices. Even better, the Mirco-USB connector is equipped with a swivel-on/swivel-off (tethered so it never gets lost) Lightning connector for charging and syncing your iPod, iPad or iPhone. The internal ratchet mechanism locks the cable at the length you need; a quick tug on it releases the catch and it's back in compact carry mode.
