An apparatus for supplying power to an electrical device 102 (for example power tools, impact wrenches, drills, screwdrivers, saws, measurement equipment) has a power supply module 106 (for example a battery) with a tether 104 (which may be flexible, extendible or helically coiled). The tether 104 has a connection for engaging with and supplying power to the electrical device 102. The power supply module 106 may have a clip for removable attachment to a body mount 108 (for example a belt) or may be positioned in a pocket of the body mount 108. The body mount 108 supports the weight of the power supply module 106. The tether connection may have inner conductive prongs (206, figure 2) for electrical connectivity and an outer sleeve (204, figure 2) for tightly securing to the electrical device 102. The tether 104 may also transmit data from the electrical device 102 to a processor.
