The Parapack™ is available for carrying the stimulator/control unit and battery pack during use, and it attaches with an adjustable strap around the user's waist. It has one compartment in which the stimulator/control unit is placed. Also within that compartment are elastic straps. The battery pack is held securely by these straps. The shorter (white) power cable should be used to connect the stimulator/control unit to the battery pack when using the Parapack™ (see photo).
