   I have a 130W Dell USB-C PSU.  It does USB-PD but strangely: it only   
   supports 5V and 20V, both at 6.5A.  So you can charge things that aren't   
   Dell laptops, but slowly.  Normally phones etc would switch up to 9, 12 or   
   15V to pull more power, but this doesn't have those rails.  They continue   
   to charge from 5V at whatever max current they're happy to take (2A, 3A?) -   
   like a dumb USB-A wall charger.   
      
   I haven't tried it on a Pi5, but I expect it would work just fine.
