1. A stand, comprising:
a first section having a first device support surface, the first section having a first near field coupling antenna comprising a first electrically conductive coil configured entirely on the first section;
a second section having a second device support surface, the second section having a second near field coupling antenna comprising a second electrically conductive coil configured entirely on the second section;
a third section connected to at least one of the first and second sections and wherein the sections form a stand configuration having the first device support surface configured at an angle relative to the second device support surface; and
electrical circuitry coupled to the first and second near field coupling antennas to allow power flow to or from the antennas when compatible externally provided portable devices are in contact with or proximity to the first and second device support surfaces, the electrical circuitry including a wired connection extending between at least two of the sections.
