Most of us have to lug along a different wall wart for each wireless device we want to recharge, but an emerging standard interface will soon allow a common station to recharge all. The Wireless Power Consortium's Qi standard promises to enable any smartphone, tablet, digital camera or similar rechargeable mobile devices to use the same wireless recharging stations--just set your device on the black pad and it automatically recharges through the air inductively: R.

Here is what EETimes says about wireless recharging:Wireless inductive battery rechargers already cut the cable to many devices such as electric toothbrushes, but because there were no standards in place until recently, they still require a proprietary recharge station. Now that the Wireless Power Consortium has over 100 members for its Qi standard, analysts predict the time is ripe for a global wireless charging market, which is expected to exceed 100 million units annually by 2015, according to IMS Research (Austin, Texas).
