a locking assembly including at least one operative detent member, wherein each one of the at least one operative detent member is disposed outside of the periphery of the receptacle;

wherein there is provided a locked state, wherein the base unit is disposed in the electrical coupling relationship with the adaptor unit and movement of the base unit relative to the adaptor unit, such that the base unit becomes disposed in an electrically uncoupled relationship with the adaptor unit, is resisted, and such that there is provided an unlocked state wherein the base unit is moveable relative to the adaptor unit; and

wherein, in the locked state, each one of the at least one operative detent member is biased into an interference relationship with the charger assembly so as to resist the relative movement between the base unit and the adaptor unit which would effect the electrical uncoupling of the base unit from the adaptor unit; and

wherein, in the unlocked state, the locking assembly co-operates with the charger assembly such that the base unit is moveable relative to the adaptor unit; and

wherein the external surfaces of the base unit and the adaptor unit include co-operating external geometries that provide a visual indication whether the charger assembly is disposed in the locked state or the unlocked state.

2. The electrical charger as claimed in claim 1 ; wherein, in the unlocked state, the locking assembly co-operates with the charger assembly such that the base unit is moveable relative to the adaptor unit.

3. The electrical charger as claimed in claim 1 , wherein, for each one of the at least one operative detent member: the operative detent member is fastened to one of the base unit and the adaptor unit, and the interference relationship with the charger assembly is effected by biassing the operative detent member into disposition within a recess provided within the other one of the base unit and the adaptor unit.

4. The electrical charger as claimed in claim 1 ;

wherein the base unit includes an electrical connector plug; and

wherein the adaptor unit includes an electrical connector plug receiving receptacle configured for receiving the electrical connector plug;

wherein the electrical connector plug is insertable within the electrical connector plug receiving receptacle such that an inserted state between the base unit and the adaptor unit is effected when the electrical connector plug is received within the electrical connector plug receiving receptacle; and

wherein an operative receiving action is defined by the action of the electrical connector plug being received within the electrical connector plug receiving receptacle; and

wherein the base unit is disposed in any one of at least two orientations relative to the adaptor unit when the operative receiving action is being effected.

5. The electrical charger as claimed in claim 1 ; wherein the provision of the visual indication is effected upon the alignment of the co-operating external geometries.

6. The electrical charger as claimed in claim 1 , wherein after the change in state from the locked state to the unlocked state, the locking assembly is disposed in co-operation with the charger assembly such that the base unit is moveable relative to the adaptor unit to effect electrical uncoupling of the base unit from the adaptor unit.

7. The electrical charger as claimed in claim 6 , wherein the relative movement between the base unit and the adaptor unit which effects the electrical uncoupling of the base unit from the adaptor unit is a rotational movement.

8. The electrical charger as claimed in claim 7 , wherein, in the unlocked state, the locking assembly co-operates with the charger assembly such that the base unit is moveable relative to the adaptor unit.

9. The electrical charger as claimed in claim 1 ; wherein the biasing is effected by a biasing member.

10. The electrical charger as claimed in claim 9 ; wherein the biasing member is a resilient member.

11. The electrical charger as claimed in claim 10 ; wherein the resilient member is a spring.

12. The electrical charger as claimed in claim 1 ;

wherein the electrical connector plug includes a plurality of electrical connector plug contacts; and

wherein the adaptor unit includes a plurality of adaptor unit contacts; and

wherein, after the electrical connector plug is received within the electrical connector plug receiving receptacle and while the electrical connector plug is disposed within the electrical connector plug receiving receptacle, each one of the electrical connector plug contacts is disposable to an electrical contact engagement state with a respective one of the adaptor unit contacts such that, when the adaptor unit becomes disposed in electrical communication with a power supply and the base unit becomes disposed in an electrical coupling relationship with an electronic device and each one of the electrical connector plug contacts becomes disposed in electrical contact engagement with a respective one of the adaptor unit contacts, power is supplied to the electronic device.

13. The electrical charger as claimed in claim 12 , wherein each one of the electrical connector plug contacts is disposable in an electrical contact engagement state with a respective one of the adaptor unit contacts by rotation of the base unit relative to the adaptor unit.

14. The electrical charger as claimed in claim 6 ;

wherein the base unit is configured to co-operate with the adaptor unit such that the base unit is mechanically coupled to the adaptor unit when the adaptor unit is electrically coupled to the base unit; and

wherein, in the locked state, the base unit is mechanically coupled to the adaptor unit and movement of the base unit relative to the adaptor unit, such that the base unit becomes disposed in a mechanically uncoupled relationship with the adaptor unit, is resisted and each one of the at least one operative detent member is biased into an interference relationship with the charger assembly so as to resist the relative movement between the base unit and the adaptor unit which would effect mechanical uncoupling of the base unit from the adaptor unit; and

wherein, in the unlocked state, the locking assembly co-operates with the charger assembly such that the base unit is moveable relative to the adaptor unit so as to effect the mechanical uncoupling of the base unit from the adaptor unit.

15. The electrical charger as claimed in claim 14 , wherein the relative movement between the base unit and the adaptor unit which effects the mechanical uncoupling of the base unit from the adaptor unit is a rotational movement.

16. The electrical charger as claimed in claim 15 ; wherein, in the unlocked state, the locking assembly co-operates with the charger assembly such that the base unit is moveable relative to the adaptor unit.
