The IDX A-CWS-TX Battery Adapter for CW-1 Transmitter allows powering the CW-1 transmitter with a Sony L series battery and mounting on camera.
This adapter features an L series battery slot, a receptacle on the side for holding the transmitter, and a cold shoe mount on the bottom for attaching to a camera. The cold shoe is removable and a 1/4" mounting thread is underneath. The cold shoe also has a 1/4" screw on its reverse end and can be flipped over, attached in a sled on the bottom of the adapter, and used as a 1/4" stud.
The battery gets connected to the CW-1 transmitter via a USB-to-mini-USB cable included with the CW-1 system. One end connects into the transmitter and the other into a 5V USB port on the side of this adapter.
