Because OP wants battery powered. A single cell 18650+DCDC+USBPD is smaller than the for example UK mains connector (volume measured).Why do you want an alternative to the RPi PSU? It is high quality, low cost, available, and does the job. It is also a USB-PD supply, so it can power other equipment at higher voltages.
