This Joyroom C-A42 car charger should be published here (perhaps; while not tested from my side like within post above mentioned VARTA 57932, sorry for that), as confirmed it is based around the fast charging protocol chip Zhirong SW3526. Yet I don’t even own here linked one, but @brandonrosano and @xpf please feel free to try it (as I’m about to test SW3518S and SW2305 controllers, Type-C port version ZC832 actually, once Librem 5 in my hands).
