USB port upgrade kit from Grazio of Japan for the Toyota 86, Scion FR-S & Subaru BRZ. Larger mobile devices require greater power and this upgrade is meant to satisfy that. This upgrade upgrades the amperage of the ports to 4.2, enough amps to charge an iPad without a problem! Due to the increased power, Grazio added two important features. First they incorporated a heatsink in the wiring to keep heat down. Second, they incorporated a fuse box to further protect the electric system. The ports also have illumination that changes color when a device is charging.
