Add dual L-Series battery support for your Sony a7 series camera with this Dual L-Series Power Adapter. The adapter features an NP-FW50 dummy battery on an integrated cable, and also offers an unregulated 14.4V, 2.5mm DC output on the side for simultaneously powering a second device. Both L-Series batteries must be used at the same time and will extend camera runtime by up to several hours, depending on the models you use.
The adapter has a 1/4"-20 threaded mounting hole on the rear for attachment to cages, rigs, and other supports; and the cable is 20" long, so you can mount the adapter on the back of your rig for counterbalance. The dummy battery is compatible with the Sony a7 I/II, a7S I/II, and a7R I/II cameras, and inserts in place of the existing camera battery. A 4-LED gauge on the front will indicate the approximate runtime remaining.
