Compact, always-ready, & tangle-free, Griffin's retractable USB (Universal Serial Bus) cable for Apple's Lightning cable-equipped devices is a must-have. In your bag, pack, or pocket, it measures less than 2 inches wide by half an inch thick, & just under 4 inches from connector tip to connector tip. But pull out the spring-loaded cable & you have a full 27 inches of tangle-resistant USB (Universal Serial Bus) to Lightning connection for charging & syncing your iPod, iPad or iPhone. Use with any USB (Universal Serial Bus) home or car charger, or with your computer. The internal ratchet mechanism locks the cable at the length you need; a quick tug on it releases the ratchet.
