1. A device comprising:
- an enclosure having circuitry associated with the device and a battery configured to power the circuitry; and
a power plug receiving unit configured to receive a power plug of a power charger to charge the battery, the power plug receiving unit including a ground contact that is exposed through the enclosure for contact with a secondary ground contact of the power plug such that the ground contract and the secondary ground contact, when coupled, create a ground return, an active electrode configured to receive alternating current (AC) energy from the power charger for charging the battery or powering the circuitry via non-contact coupling, and a dielectric material disposed between the active electrode and the ground contact such that the ground contact is electrically isolated from the active electrode.
