Switronix has a new power cable for Nikon DSLRs that provides access to hours of runtime from any V-mount or 3-Stud battery. The Switronix XP-DSLR-EL15 power cable is compatible with all Nikon DSLRs that accept the Nikon EN-EL15 battery (like the Nikon D800 or D600).
The cables feature a regulated 9.2v battery paddle and an inline female P-Tap connector for 12vdc, housed in an enclosure. The XP-DSLR-EL15 also includes both red and green LED indication to display status of battery power.
Switronix power cables have been available for Canon DSLRs and other cinema cameras for quite some time and have proven popular for extending shoot time in video projects. For more details on the new Switronix XP-DSLR-EL15, check out Switronix’s website. It should be available soon at B&H Photo and other retailers.
