When you're back at the rest site, whip out the rugged Scosche clipSYNC Charge & Sync Cable, which makes recharging your device a breeze.
A carabiner clip keeps the clipSYNC attached to your backpack, travel bag, or keychain, and its efficient design keeps the cable and plugs stowed away in an attractive, compact package.
Of course, you'll need to plug the clipSYNC into a USB port or power adapter in order to charge your device.
