5V/5A means at least 25W. Plenty of chargers at that level and above on Amazon.

25W is easy, but most of them will not do it at 5V. I checked one of my 100W chargers, it'll only do 5A @ 20V. 3A at every other voltage. Looking at many other chargers on Amazon do the same.

Most 65W chargers are 20V/3A. Standard USB cables are built to carry at most 2-3A, and e-marker cable authentication chips are required for 5A, I believe, because people running 100W on a random USB cable is scary.

Chargers that would do 5V/5A probably do PD 20V/5A as well, = 100W. Or it'll be a non-conforming special Pi PSU of sorts.

Unfortunately that's not how USB PD works. In PD Land, 25W means 9V/2.8A. A charger is allowed to offer 5V/5A but at no power level is it mandatory, so even a fully USB PD compliant 100W charger which can do 20V/5A is not guaranteed to power the Pi 5.

I just did a quick review on Amazon of adapters ranging from 30 to 120W. Not a single one claimed to support 5V/5A DC. Only a couple claimed 5V/4.5A and they were expensive. 5V/3A is common in the $15+ category.
