The idea of charging your phone without plugging it in seems appealing, but consumers have been slow to adopt it. At a time of wireless everything—from phones and Internet to headsets and keyboards—it seems tedious that our gadgets remain tethered to an outlet whenever they need a charge. It’s especially galling given that the technology has been available since Nikola Tesla first demonstrated wireless power through magnetic induction in the 1890s. Why hasn’t cord-free charging—where a device gets charged when you place it on a charging surface—caught on? It’s not due to a shortage of products, nor from a shortage of companies that want to sell them.
