IndiPRO's 2.1mm to Sony NP-FZ100 Dummy Battery Cable allows you to power select Sony Alpha series cameras from power sources with a 2.1mm DC input. The cable is unregulated, so the output of the power source has to be within the range of 7.2 to 8V. Compatible cameras include the a9, a9 II, a7R III, a7R IV, a7 III, and a6600, all of which use an NP-FZ100 battery. The cable measures 20" long.
