Sigma's IICON is a cable that turns the company's battery packs — intended to power bike lights — into portable USB charging stations that can be used to power any electronic gadget, including cell phones, cameras or GPS units.
The IICON attaches to the IION/IION XL battery pack and a red LED indicator light shows that the device is being charged. The IICON is completely watertight for use even in damp conditions.
MSRP: $19.99. Also available as a set with Sigma's Karma EVO or PowerLED EVO lights.
