The Radio USB Charger compact adapter with USB-C port and radio battery connection
The Radio USB Charger — Portable charging adapter

Overview

The Radio USB Charger creates a portable charging scenario for radios that normally depend on a dedicated dock. The compact adapter enables charging through USB-C, allowing the radio to be powered in a wider range of locations.

One Week

The Radio USB Charger process from ideation through product development to prototype
Ideation · Product development · Prototype

Project Direction

The one-week project focused on translating an existing dock-charging workflow into a compact accessory that could travel with the radio.

Concept sketches and early form models for the portable radio charging adapter
Form, interface and attachment studies

Ideation

Early concepts explored how the charger could wrap around the radio battery, expose the required interfaces and remain visually compact while attached.

Existing radio geometry and adapter development

Dimensional Integration

The existing radio was modelled dimensionally so the adapter could be developed around its real proportions and attachment points.

Electronics Collaboration

PCB dimensions were defined together with the electronics team. The board integrates a USB-C input, a triple pogo-pin connection and a feedback light within the compact enclosure.

Support Geometry

Angled surfaces on the adapter allow the radio to remain upright while the charging equipment is attached.
