That doesn't sound right.

Raspberry Pi sell three different USB-C PSUs:

- A 15W PSU for use with the Pi 4/400 only.
- A 27W PSU for use with the Pi5/500 (and 4/400)
- A 45W PSU which is like the 27W but more powerful and can power some 
laptops, etc.

The 27W and 45W PSUs support the USB Power Delivery spec and will 
provide a range of powers/voltages after negotiation with the device. 
The 15W PSU provides only 5V/3A, and is stated to be inadequate for the 
Pi5 and later.

There is no official "kosher" 25W PSU from Raspberry Pi.
