A mobile strapping device for strapping packaged goods with wrap-around strap, comprising a tensioner for applying a strap tension to a loop of a wrapping strap, and a connector for producing a connection in two areas of the loop of the wrapping strap disposed one on top of the other, and a chargeable energy storage means for storing energy that can be released as drive energy for motorized drive motions at least for the connector and/or for the tensioner, is intended to have high functional reliability and ease of handling despite the possibility of automated production of wrapped straps, at least to a large extent. In order to accomplish this, it is proposed that the strapping device be provided with a brushless DC motor as a drive for the tensioner and/or the connector.
