Compact rectangular metal case with hinged lid and dark green enamel finish. A Telefunken manufacturer’s label and serial number plate are affixed to the top surface, next to a patch of aged adhesive residue.
When opened, the interior reveals a charging assembly composed of three cylindrical metal connectors mounted in a red-brown Bakelite base. A central socket likely serves as the power interface, while the outer connectors act as contact terminals for charging or testing batteries. Corrosion is visible on several metal components, indicating prolonged exposure to moisture or battery chemicals.
This compact unit would have been used to recharge or regulate power for Telefunken PE-484 field communication sets, ensuring continuous radio operation in remote or mobile environments.
