Updated Qi wireless charging means your phones won't have to be directly touching the charger

The new Qi v1.2 specification will enable wireless charging through even greater spans than before. The current Qi standard is capable of blasting power wirelessly through up to 7mm of space, but the new standard amps that up to 45mm (1.77 inches). This will make it much easier to embed Qi chargers inside of things (like desks, tables, cars, blocks of cheese, etc).
