Core's Cube Plus is a lightweight, all aluminum 120w on-board power supply capable of powering a camera or device, while simultaneously charging an on-board battery pack up to 3A* per hour(~2hrs to fully charge a 98wh pack).
The Cube Plus, when having an on-board pack mounted, is designed to act like an uninterruptable power source should AC mains power be disconnected. Not only will the device switch from AC to on-board power for the camera or device, but the two p-tap connections are also backed up.
The Cube Plus has internal protections along with a replaceable 10A fuse. It accepts 100-240VAC, making it useable worldwide and it includes an AC power cord. Furthermore, it's fan-less, and operates silently.
