Got a Nexus 4?  Good news.  Today, Google began selling their long-awaited wireless charging orb.  To be candid, this technology isn’t anything new, as we saw something comparable from the likes of PowerMat years ago.  However, what makes the Nexus 4 and the orb so attractive is that it doesn’t require a special case attached to the smartphone; it’s built-in.

If you’re not familiar with the tech, it’s called inductive charging, which uses magnets to transfer power over a very short range, otherwise known as an electromagnetic field.  Wikipedia describes it as such:

Induction chargers typically use an induction coil to create an alternating electromagnetic field from within a charging base station, and a second induction coil in the portable device takes power from the electromagnetic field and converts it back into electrical current to charge the battery. The two induction coils in proximity combine to form an electrical transformer.

Inductive charging has long been used in electric toothbrushes since it reduces the risk of electrical shock – there are no exposed conductors (plugs).  Also, corrosion is seriously mitigated since everything is enclosed, or sealed in.  Obviously there is the simple convenience of just placing the phone down.  There is however a caveat: charging will take longer since by the very nature of inductive charing there is some power loss.

The Nexus 4 wireless charger should ship in the next week.  I just ordered one for $60 (plus shipping and tax).   Alternatively, there is the TYLT Vu.
