In the portable case, is accommodated one half of a recharging unit consisting of a secondary winding of a transformer and a coil which is encircled thereby. The primary winding and associated core is accommodated in the base. When the portable casing is accommodated in the base, the cores are juxtaposed in coaxial alignment, whereby an alternating current source coupled to the primary winding charges the rechargeable battery arrangement.
