The Regulated P-Tap to NP-FW50 Dummy Battery Cable from Anton Bauer allows you to power your Sony a7, a7R, a7S, a7R II, or a7S camera using a professional P-Tap battery such as the Titon Base. The cable measures 20″ in length and provides a P-Tap connector on one end and an NP-FW50 dummy battery on the other end.

The cable is regulated to provide the 7.4V required to power the camera. The P-Tap provides reverse polarity protection, allowing you to plug the P-Tap connector into your battery either way and will prevent damage to your equipment.
