Abstract: A power adapting device has a connecting seat, at least two conductive strips, and an adapter. The connecting seat has a mounting portion with two slots. The at least two conductive strips are mounted in the connecting seat. Each of the at least two conductive strips has a positioning sheet, a conductive sheet obliquely protruding upward from the positioning sheet, an arced sheet protruding down from the positioning sheet, and an engaging sheet protruding down from the arced sheet. The engaging sheet has a semispherical contact. The adapter is electrically connected to the conductive sheets of the at least two conductive strips. With different power adapting devices of different standards using in cooperation with a charger, the charger can comply with different electrical socket standards via the power adapting devices.

Abstract: A plug device with a changeable adapter has a base and an adapter. The base has a transformer circuit and a first connecting component. The adapter is detachably mounted on the base and has two prongs and a second connecting component selectively connected to the first connecting component of the base. When a user goes on a trip abroad, the user is capable of replacing the adapter to fit sockets of a specific country and to supply electrical power to electronic devices that the user carries along.

Abstract: The present invention relates to a battery charger with multiple functions comprises a charging unit and at least two adaptive connectors. The charging unit controls output voltages via software and has a display screen showing set voltages. A voltage select button provides convenience of voltage setting by touch button (or keys), the adaptive connector between the main charger and a charged device sets limited output voltages range, providing end user to select required voltages for various products. End users can power/charge many electrical products with one charger only.

Abstract: A power supply lock has a recess defined in a side face of the connector body and having a clamping plate extending out from a distal edge defining the recess. The clamping plate has a hook formed on a free edge of the clamping plate so as to correspond to one of the tracks of the digital camera to allow the power supply to securely engage with the digital camera.
