The Atomos Power Station Video dual-battery system keeps your film production up and running. It needs to be fixed beneath a camera with the help of its 1/4"-20 screw with thumbwheel. With the dual USB ports, this power station can charge two devices at the same time or a single high-powered 2A device. It has slots for Sony L-Series batteries. Each battery slot in the Power Station has an independent level indicator that displays, through LED lights, how much battery capacity is available. Also, the batteries are hot-swappable, which means they can be replaced while the connected devices are operational. The power station has an ABS-polycarbonate body that offers rigidity and durability.
