This adapter with clip mount and Sony NP-F970 battery mount plate makes your job easier when using a smartphone for monitoring. The plate secures to the clip mount using an included 1/4"-20 tie down screw. A shoe mount adapter, 2.5mm 12V DC cable and USB type-A to type-C cable are also included. The unit features 1/4"-20 threads, letting you attach it to tripods or stands.
The battery plate can power multiple devices when used with a Sony-type L-series battery like the NP-F970 or NP-F770. It offers a series of outputs and interface ports, including a 2.5mm 12V DC barrel (which can power BMPCC 4K/6K cameras), 2.1mm 8V DC barrel (which also works as an input), 5V USB Type-A, and 5V USB Type-C (which can charge the battery even while it's working and can also automatically switch to 9V for fast charging). It also features a power switch and indicator light.
The clip mount can extend to hold smartphone from 2.3 to 3.3" in width and has a padded interior to protect your phone's finish.
