Summary: Mophie, maker of mobile phone battery packs, has introduced the only thing I’ve wanted to buy from them in quite some time: a wireless charging case. Its new Mophie Charge Force case is a battery-free leather case that has a built-in Qi-compatible wireless charging receiver. You’ve probably seen wireless charging pads in places like IKEA or Starbucks, round inserts in tables or lamps on which you can place your phone to charge.
