The CordDock ships with a specially designed cable (Lightning for the iPhone model, USB-C for Android) that works with the dock in two separate ways. Pull your phone straight up to remove it from the dock entirely. Or, rotate it forward to keep the cable plugged in while disengaging it from the dock, allowing you to use the phone to send a quick text without stopping the charging process.
Like all Elevation Lab stuff, the CordDock is incredibly well designed, and the new V2 model on sale today features stronger welds, more friction on the rear adjustment knobs, and other tweaks to make it even nicer to use. Just use promo code KINJAROCKS to get either one for $22.
