Yes, I already pay the $12.99 monthly for the member rate as I charge so often at Superchargers for my Ford EV.The compatibility with Tesla’s supercharger NACS network is virtually guaranteed. While ‘Slate’ is not yet listed, I bet I could charge it today using “other.”
However if you want to pay lower Tesla rates, you need to sign up for the $12.99 monthly membership fee. Fisker, Lucid, Rivian, Vinfast, as well as all domestic manufacturers are listed in Tesla’s charging app.
According to Tesla website: Note: Supercharging Memberships allow you to use the benefits on all EVs you own. You do not need to purchase a membership for each vehicle.
