I loved this cable- it charged very fast and appeared to be a quality robust product. Bought it in Sept 23, and stopped working for no apparent reason in Feb 24. No visible wear, no gunk in the ports, still looks new. I ordered new, different usb-c cables and they didn’t work either! Turns out recent Apple updates are the problem if your settings are checked for “Battery Optimization” and “Clean Energy”. I unchecked both and everything works. Charges fast again. Sorry Anker for the temporary diss.
