From the Griffin website: >Please note that BreakSafe is for charging power only; data and video are not supported. So you're paying $40 for a non-standard USB cable that'll confuse the hell out of less-technically-inclined users. Also, non-Thunderbolt "USB-C" docks won't do anything that USB 3.0 A docks don't. I've seen people run Gbit Ethernet + HDMI out + HDD from a single USB 3.0 port with no problems.
