I have had poor luck with the small round "USB-C + USB-A" sockets from Amazon. The unit I got claimed to be 60W but if I plug my Steam Deck into the USB-C it gives me a "slow charger" notification. It does charge, but not at a high enough rate to use the device without running the battery down. So that's less than ~28W actual power delivered via USB-C, probably a lot less.
Did I just buy the wrong thing? These PD units seem to claim 65W from a single PD port.
