Wireless charging sounds mighty convenient if you regularly deal with a jungle of wires, doesn't it? Samsung's wireless charging kit for the S 4 is one option now that it's available in the US. It uses the Qi wireless charging standard, so if you already have a Qi charger, all you'll need to do is grab the backplate for $39.99. Otherwise, you can also snag the charging pad for $49.99. Hit the source for more info if you're convinced this is what you've been waiting for your whole S 4-using life. The components don't seem to be in stock right now -- we couldn't add them to our cart -- but even if you get lucky, you might want to hold off on clicking that Buy Now button until you've seen its alternatives.
