1. If Raspberry Pi5 firmware detects this power supply, it will increase the USB power limit to 1.6A, providing 5W of extra power to downstream USB devices and 5W of extra power to the internal power supply: For those who want to try overclocking Raspberry Pi5 and a big advantage for users who want to power high-performance peripherals like hard drives and SSDs 2. When using the standard 5V 3A (15W) USB-C power adapter on Raspberry Pi5, the downstream USB power must be limited to 600mA to provide enough headroom to support these workloads. 3. This is lower than the 1.2A limit on Raspberry Pi4, but is still usually sufficient to power mice, keyboards, and other low-power peripherals. 4. The USB-C PD power adapter can also provide 3A @9V, 2.25A @12V, and 1.8A @15V for products that support the PD standard. It is a universal and cost-effective product, not just for Raspberry. 5. 27W USB-C Interface PD Power Adapter Name:27W USB-C Power Adapter Input:100-240V AC Output:5A @ 5.1V, 3A @ 9V, 2.25A @ 12V, 1.8A @ 15V Port:USB-C Cable Length:1.2m Note:Different batches may have differences in product appearance, color, and printed characters, which does not affect the use Connector Type:EU plug, it applies to Indonesia, Germany, France, Italy and so on.
