Upsides: Probably the cheapest 140W GaN charger from an Australian retailer. Comsol brand is also available at other retailers including officeworks.
Downsides: 3 USB C ports and no USB A port. Does not mention PPS, however many GaN chargers do not specify PPS and yet support it and this maybe the case here as well.
Personally I prefer Zyron 140W when on special as it comes with 240W cable, travel adapters, hard case and option to convert in a desktop charger with figure 8 cable and for the built quality.
