Abstract

An integrated power supply and battery charger (1) with interchangeable and collapsible plug includes a casing (1), an electrical plug detachably mounted in the casing (1) and including collapsible prongs, allowing the user to accommodate myriads of combinations of power source configurations, electrical devices and rechargeable batteries. Releasable locking mechanisms are included to both engage the interchangeable electrical plug and battery and to lock the prong in the extended position. A variety of plugs can be fitted to the same casing (1). A power supply is preferably fitted within the casing (1), allowing an electrical device (8) to be attached while the device is also acting as a battery charger.

Claims

AMENDED CLAIMS[received by the International Bureau on 15 April 1997 (15.04.97); original claims 1 and 2 amended; remaining claims unchanged (3 pages)]
