Cuebi D-Tap to USB Adapter

The Cuebi Light has no internal battery on purpose, which leaves the choice of power source to the rig. On a camera already carrying a V-mount or gold-mount brick, the obvious source is the D-Tap, and this adapter is what makes that usable: D-Tap in, USB out, feeding the light's 5 V micro USB input.

That removes the separate battery pack from the build entirely. The Cuebi Light draws 0.4 W (80 mA), so the load on the camera battery is negligible, and the light powers up and rejoins the switcher network within about ten seconds of the D-Tap being connected.
