The D-Tap to Dummy NP-FZ100 enables you to power select Sony Alpha cameras (those using an NP-FZ100 battery) with any V-Mount or Gold Mount battery equipped with a D-Tap plug. The mid-cable voltage converter box adapts 14.4v to the standard 7.4v required by the camera. It also features built-in reverse polarity protection, ensuring the cable remains undamaged if plugged in backwards to a D-Tap.
