The new 27W USB-C PD power supply delivers a maximum of 5.1V and 5A, allowing the Raspberry Pi 5 to power a larger number of peripherals. The total current drawn by the Raspberry Pi 5's four USB ports is limited to 600 mA by default. This limit is automatically increased to 1.6A when the USB-C PD power adapter is detected. The USB-C PD power supply can also supply 3A @ 9V, 2.25A @ 12V and 1.8A @ 15V to PD compatible products, making it a good and cost-effective power supply for many general use cases that are not available with the Raspberry Pi related.
