The Switronix V-Mount JetPack with XLR Camera Output is a battery and power output adapter for cameras with 4-pin XLR power inputs, like the Sony F3. JetPack features a V-Mount for a battery and six outputs for powering various accessories. Specifically, the outputs include two P-Taps, one 5V Lemo, one 7.2V Lemo, a 12V Lemo, and one USB output. You can use the P-Taps, for example, to power compatible monitors and lights.
Three 1/4" threads are available for mounting. You would need to use a plate that configures well with your rig. An optional Switronix JetPack cheese plate can be attached to additionally provide thirteen 1/4" and ten 3/8" threads.
