According to QInside, Qi is Chinese word for energy flow and pronounced like the chee of cheese. It is the universal standard of wireless charging of battery operated devices through electromagnetic induction. Through electromagnetic fields, the required power of up to 5 watts reaches the device wirelessly, not through a cable.
