Do AirPods charge batteries with Qi now? The Apple page about "Wireless Charging" talks about Apple's new AirPower mat due in 2018 working with iPhone, Apple Watch, and AirPods. Elsewhere it talks about standard Qi charging technology being used.

Does that mean today’s AirPods charge with any Qi-compliant charging pad?
Yes, but... 

Current AirPods can only be charged with a Qi-compliant charging pad if they're in the appropriate case. By appropriate case I mean Apple has launched a new optional charging case that supports wireless charging for AirPods.

Apple Intros AirPower Charging Mat, Wireless Charging AirPods Case



  Apple revealed a new AirPods case that works with Apple's new AirPower charging pad. To charge the new wireless case, you place it
  on the AirPower. If your AirPods are in the case, you’ll see an orange
  light if they’re charging, or a green light when they’re nearly fully
  charged. If no AirPods are in the case, the light still goes on when
  you open the lid, but it indicates how much battery life is left in
  the case itself: orange for needs charging and green for good life
  left.
  
  As of this writing, Apple has not released pricing for the new
  wireless case, nor has the company said that it will replace the
  original case with the new one with a new pair of AirPods. The
  wireless case will be available in 2018.
