Sony has released a new wall charger. The brick is USB-PD-compliant and supplies just under 40 W at its peak, and a total power output of 46.5 W. The fast charger will work on all devices with USB-PD support, which makes for a rather long list.

The source article mentions its model number: CP-ADRM2.
This is good, I think it would be worth buying on its own. Still can't fully replace laptop chargers, with some popular laptops requiring about 65W minimum.
It's a shame that proprietary charging standards ever carried over to type-C. I have a type-C device (a soldering iron, oddly enough) that only works with a single Samsung QC charger (Qualcomm quick charge) of mine--none of my USB-PD chargers work with it. Uses 9V/3A, which is a PD profile but it must be some negotiation failure.
