Abstract:
The present disclosure addresses the problem of providing a power feeding system with improved operability. A power feeding system (10) feeds power to an electric tool (21) which can be hand-held. The power feeding system (10) comprises: a first storage battery (111); a power feeding circuit (112); a second storage battery (211); and a tool holding unit (12). The power feeding circuit (112) converts alternating-current power from a commercial power source (300) to direct-current power and feeds the direct-current power to the first storage battery (111).
The second storage battery (211) is built into the electric tool (21), or is built into a battery pack (22) that can be attached to the electric tool (21). The tool holding unit (12) is capable of holding a battery-equipped electric tool (2), and feeds the power of the first storage battery (111) to the second storage battery (211) while holding the battery-equipped electric tool (2). The battery-equipped electric tool (2) is the electric tool (21) with the second storage battery (211) built therein, or is the electric tool (21) to which the battery pack (22) with the second storage battery (211) built therein is attached.
