What sucks is, Tesla's chargers will only charge Hyundai/Kia vehicles very slowly (50kW) due to a mismatch between their 400V and the 800V of the cars. I was hoping that they'd announce a fix to this, but... nope.

Cynically, this is probably why they're releasing new, NACS-enabled cars (which will presumably charge at full speed on Tesla chargers) before releasing the adapter -- so that when owners of the existing cars realize how bad the experience is, new buyers will already have a better car available to buy, and won't need to worry about how this transition screwed over everyone who already bought a Hyundai/Kia EV.
