The Tilta DB-SYA9-PTAP Sony A9 series Dummy battery cable with P-TAP connector is a dummy battery cable designed to convert the Sony NP‑FZ100 battery socket into a male P-TAP connector, allowing Sony A9 series cameras to be powered from external sources via P-TAP. The cable is approximately 43.82 cm long and lightweight, with a rubber coating and components made of ABS and aluminium alloy for flexibility and durability.
A regulation circuit is integrated inside the dummy, which transforms the input voltage from P-TAP to the correct voltage required by the camera. This ensures electrical compatibility and protection against power surges.

On the “dummy battery” side, the connector plugs into the camera’s battery compartment, replacing the physical battery; on the other side, the P-TAP connector connects to the external power source.
This type of solution, the Tilta DB-SYA9-PTAP Dummy Battery Cable, is particularly useful in film rigs or during long video sessions, where it is preferable to power the camera from a single external battery rather than from internal cells.
