The Qi (pronounced "chee") interface standard developed by the Wireless Power Consortium provides inductive electrical power transfer over distances of up to 40 millimeters (1.6 inches).
That means that devices in very close proximity with a Qi power charger can regain their energy wirelessly, provided they are Qi-compatible.
LG has just launched the smallest Qi wireless charging adapter in the world, called WCP-300. It is smaller than even a tea cup.
It works with the company's own Optimus G Pro, Vu II and LTE II smartphones, but will serve well any other gadgets that can wirelessly recharge, like the Google Nexus 4.
Sales, in South Korea at least, will begin this week for 65,000 won (roughly $60 / 46 Euro).
Other countries will receive it over time, but no clear roadmap has been revealed as of yet.
