I have this: https://www.amazon.com/dp/B06XXQ1P28/ref=cm_sw_r_other_apa_i_oaYDEbGXAKBN6

Been using it daily for a few years. It's not super fast but it's still fast. From the research I've read, IIRC the 45w chargers don't do much for the ultra right now. That said I haven't looked for a super fast car charger, sorry. And I've been reading up on heat and battery longevity and am not sure how I feel yet about the super fast and heat on battery (a whole other discussion).
