This Fuji Retractable Power Cable is specifically for their S1240 D/N and 16x40 binoculars. This cable is to be used with the dc regulator. It provides more distance between the two units. The two ends of the cable retract into the centrally located housing so it is less likely to become knotted or twisted.
