Add dual L-Series battery support for select Canon cameras with this Dual L-Series Power Adapter. The adapter features an LP-E6 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 select Canon cameras and other devices, and inserts in place of the existing camera battery. A 4-LED gauge on the front will indicate the approximate runtime remaining.
