I've been looking for the best volume to wattage 100W+ GaN charger for a while. I would get the Anker GanPrime 747 150W as it's ~1.4x more power dense but I don't know when/if it'll release with an AU plug and it'll probably never hit $75 so. Compared to the Anker, this charger supports PD3.1 140W charging and has an extension cord and international adapters (the AliExpress version comes with them).
It has been reviewed by this youtuber (timestamped) who reviews power adapters and it has solid performance relative for its wattage. The idle power is a little on the high side (0.24W) but if you watch the reviews for other chargers in the 100W+ range, they are all around this mark typically due to having Power Factor Correction (necessary for 75W+ chargers) which is why the power quality scores for this charger are so good.
The one without an extension cable and has ratings is also available here but it's more expensive than this one so… just read it for ratings?
