Looking at the charging preferences of the Steam Deck, which from my research wants 45W at 15v/3A, it looks like the larger model should work just fine. And with it being $15 USD / $18 CAD this could be an incredible bargain.

It's so new though I can't find any info on it being used with a Steam Deck. I'll definitely be grabbing one to try, as it would be perfect for my USB hub that sits by the TV.

The deck uses standard USB PD protocols to request power, so yes, these should work.

Worth noting, the Deck used to be unable to charge using PD chargers that were rated at less than 40W, this has been fixed in a firmware update and it is now able to correctly request power from any USB PD charger.

To charge while playing, a PD charger with a 15V mode is required, but any PD charger that can do 5 or 9 volts can still charge the Deck while idle/sleeping.

The only limitation that I ever saw was - if you're using a USB-C to USB-A cable to connect to your charger, the deck will say "charging slowly" while pulling absolutely nothing. It will only pull USB-C PD power. If you have a huge battery bank that can put out tons of 9v power on a quickcharge A socket, too bad.

USB-A, per the specification, is only supposed to provide 5V max. Qualcomm Quickcharge violates the USB-A specification, so only other devices that are designed to violate the specification and thus be compatible with QC will charge faster.
