Charging speed can depend on a bunch of things, like battery temperature. You should check out the State Of Charge YouTube channel they did a review of the Kia EV6 and even made a graph showing how charging speed changes. It's really helpful for understanding how it all works.
@Pharah_Rocket I'm with them on that. Kia and Tesla definitely need to hash this out. I mean, Tesla's site still doesn't list Kia as having NACS access, so something's clearly not right.
I keep hearing about problems with Wallbox chargers. That's why I'm not a fan of all those "smart" features. Too much to break, you know? I just want a charger that works plug it in, and it charges, simple as that.
