Needed a couple of extra chargers. Found this 25W PPS USB-C PD (latest adaptive fast charge technology) wall charger at DJ's which includes a 1m USB-C to USB-C cable. It is $39.96 at Amazon. https://www.amazon.com.au/Belkin-Delivery-Charger-Adapter-En…. The same charger without the cable is $29.95 at JB HiFi https://www.jbhifi.com.au/products/belkin-boostup-charge-25w…. I bought 2 so delivery is free.
(I am using it for 2 new Pixel 6 Pro's. Note that due to Google's charging algorithm the Pixel 6's don't charge much faster with PD PPS chargers than with the old 18W charger. See this article. https://www.androidauthority.com/google-pixel-6-charging-tes…. The Pixel 6 and 6 Pro draw max 22W and 23W respectively. You will need to check spec and requirements for your devices.)
P6 Pro owner here - agreed on the slow charge rate. Best for me is ~18W with a Dell 65W USB-C PD charger, also the ZMI 815 PD power bank (using USB-C not USB-A). No improvement using a Samsung PPS charger.
