The Hähnel ProCube 3 charger (Sony version) is a professional dual battery charger designed for Sony camera batteries (NP-BX1, NP-FW50, NP-FZ100) and AA Ni–MH cells. It features a USB-C PD input (recommended power 30W+) and a USB-A output for charging other devices.

The charger uses interchangeable battery trays to accept Sony camera batteries or a 4-slot tray for AA batteries. It includes an LCD screen that displays the charge percentage per port, the added capacity in mAh, input power and charging current, as well as battery diagnostic status. It charges one or two identical camera batteries simultaneously using intelligent fast charge control and supports quick top-up charges.

The charger includes tools for changing trays and a USB-C cable in some packages. It is built with an aluminum case in a compact cube form. A dedicated AC adapter is not included (it uses standard USB-C PD adapters).
