Greate to hear that!
I found Lumsing's 48W usb-c/usb QC3.0 charger from amazon works for me very well. Due to SA12's lack of multiple usb ports, a multi-port usb-c charger makes my road trips easier when it comes to keep SA12, iphone, ipads charged. Finally I don't have to carry the clunky factory charger around anymore.
It's interesting that someone from Acer posted on Amazon that SA12 needs to take 20V input for its usb-c charing to work, and I have tried three different usb-c charger with 20V capabalities (Anker, iVoler, RAVPower) and none worked. Both yours and mind have a max 14.5V output and both work.
