The Elantra relies on "Android Auto" or "Apple Carplay" for its Navigation features among other things. However they don't provide any place to put your phone when your driving. Even worse, most smart phones draw more power from the cars built-in USB port than the port can provide, so the phone battery steadily drains. To exacerbate the situation further, to use "Android Auto" you must plug into the car's buit-in USB. As a workaround, this charger should be able to wirelessly charge the phone while Android Auto uses the USB port. A bit messy but it works.
