Having to plug your smartphone or other device in to charge in your car or home isn't difficult. It is inconvenient though to have to mess with chargers. Charging would be much easier to do if all you had to do for charging of your device was place your phone on a table or charge tray. There are some cases and tech available today that will let you charge with no wires. The main standard for this is called Qi and you can get cases for smartphones already that support the open standard.
