Historical information

The box is cleverly designed to give quick access to the parts inside, having a lift-up lid and a pull-down front. The components within appear to be a portable radio, power supply or power converter with batteries and a charger. The attached leather strap makes the equipment easily portable.

Significance

The portable power supply is significant for representing part of the evolutionary change in communications. The unit connects the use of power and radio for communication with the ability to save the power in power packs or batteries, or to convert the power from one form to another.
