The Voltster™ consists of a novel one-handed connector, a power controller, and a belt-mounted battery pack, and is used to separate the weight of the batteries from the power tool, This allows much smaller tools, with the same or greater peak power and life. It is applicable to both existing and new portable power tools.        

Instead of batteries in each tool, the battery pack is mounted on a tool belt, and can power a wide range of portable power tools, intelligently supporting different power and voltage requirements. To connect a power tool to the pack, the user swipes the tool over the belt-mounted connector (Figs 1, 2).  This engages the connector to the tool, releases it from the belt (fig 3), then interrogates the tool, and turns the appropriate level of power on via a circuit breaker. To release the tool, the process is reversed. The tool-mounted connector can be designed into new tools, or be part of a battery-shaped adapter for existing tools.

Our prototype is under construction.
