Whether you're driving between work meetings or just running errands, you don't want to find yourself with a dead HTC Hero. The Retractable Cable Charger Package provides three ways to power up your device; it comes with a retractable USB cable that you can plug into a vehicle charger or a wall adapter (both are also included), or your computer for charging and syncing the smartphone. The Sprint HTC Hero Retractable Cable Charger Package costs $29.95.
