Meh, unnecessary in my opinion. I just use the extra long USB cable that came with my One and plug my controller straight into the console itself to charge it when it runs low. A simple snap of the cable to the controller and I can keep playing while I do it. I don't even have to have it plugged into my One, I can plug it into my cell phone USB outlet adaptor and charge the controller off a normal wall outlet while playing. Of course I only have one controller so I can get away with that. But it would also work with multiple controllers. Just have one plugged in via USB and use one that's unplugged.
