Anton Bauer Tandem 150 Modular Power System Charger and On-Camera Power Supply -
The Anton Bauer Tandem 150 Modular Power System does double duty as both an on-camera DC power supply and battery charger at the same time. Dividing its 150W output evenly between camera and battery, the Tandem 150 will automatically stop charging and switch to a full 150W power supply if the camera draws more than 75W. Using the included QR-TM Gold Mount device to attach a wide range of Anton Bauer batteries to your camera, the Tandem 150 not only reduces 80% of the heat that can come from the back of a camera, it's the smallest, lightest such device on the market. Can also be powered via an optional cigarette adapter or solar panel.
