Samsung seem to excite everyone with the accessories they provide for their smartphones but sometimes take a while to come out with them. The Galaxy S4 was released at the beginning of last year and after a year they come out with its much awaited S-View Flip Cover with Wireless Charging. The back cover enables the Galaxy S4 to charge wirelessly on the Samsung Charging Pad which is of course sold separately. People at work usually keep their smartphones on charge all the time as the battery sometimes does become an issue with heavy everyday usage.
So now you do not have to worry about plugging in or taking out the S4, you just have to place it on a pad and voila! The Cover itself costs $70 so it is a bit expensive but if you want your wireless freedom, then go ahead with the purchase.
