## Specs

| Spec | Value | Source |
|---|---|---|
| Input | 100 to 240 V AC | source Product brief p.3, Specification |
| Output profiles | 5.1 V 5 A; 9 V 3 A; 12 V 2.25 A; 15 V 1.8 A (USB Power Delivery), all limited to a maximum of 27 W | source Product brief p.2-3 |
| Connector | USB-C | source Product brief p.3, Specification |
| Cable | 1.2 m, 17 AWG, white or black | source Product brief p.3, Specification |
| Plug types | US and Canada (type A), Europe (type C), India (type D), UK (type G), Australia and New Zealand (type I) | source Product brief p.3, Specification |
| Raspberry Pi 5 behaviour | Supports USB PD so Raspberry Pi 5 can raise its USB current limit from the default 600 mA to 1.6 A for the four Type A ports | source Product brief p.2, Overview |

## Power

| | Value | Source |
|---|---|---|
| Supply | 100-240 V AC mains input; outputs 5.1 V 5 A, 9 V 3 A, 12 V 2.25 A or 15 V 1.8 A over USB-C | source Product brief p.3, Specification |

## Pinout
We don't publish a pin table for this part: no official source we could verify gives one. Check the labels printed on your module, and see the notes below.

Output is a captive USB-C cable; the brief gives no pin table.

## Build with it
Project ideas for the Raspberry Pi 27W USB-C power supply. Each link opens Soldr with the prompt filled in; Soldr assigns the pins, checks power and shows how to wire every part.

- [Raspberry Pi 5 desktop](https://app.soldr.ai/?prompt=I%20want%20to%20build%20a%20desktop%20computer%20with%20a%20Raspberry%20Pi%205%20in%20its%20case%20with%20a%20cooling%20fan%20and%20the%20official%2027W%20USB-C%20power%20supply): The supply is made for the Raspberry Pi 5 and its 5.1 V 5 A profile is negotiated over USB PD, which lets the Pi raise the USB current limit to 1.6 A.
- [NVMe boot server](https://app.soldr.ai/?prompt=I%20want%20to%20build%20a%20Raspberry%20Pi%205%20file%20server%20that%20boots%20from%20an%20NVMe%20SSD%20powered%20by%20the%20official%2027W%20USB-C%20power%20supply): The Pi 5 powers the NVMe board over its PCIe connector, and the 5 A profile supplies the Pi and its USB ports. Learning project.

Learning project.

## Common mistakes

- Opening or modifying the adapter or its cable: the brief says not to open or remove the case, and any mains-side work needs a qualified person (source: [link](https://datasheets.raspberrypi.com/power-supply/27w-usb-c-power-supply-product-brief.pdf), p.9 Safety instructions)
- Assuming 27 W is available at every voltage: each profile has its own limit (9 V 3 A, 12 V 2.25 A, 15 V 1.8 A) and the 5 A profile is 5.1 V (source: [link](https://datasheets.raspberrypi.com/power-supply/27w-usb-c-power-supply-product-brief.pdf), p.2-3)
- Using it with wet hands, on a conductive surface or somewhere hot: the brief says to keep it away from water and heat (source: [link](https://datasheets.raspberrypi.com/power-supply/27w-usb-c-power-supply-product-brief.pdf), p.9)

## Not covered by the official source

- The brief gives no operating temperature, efficiency or protection ratings.
- This page covers the black variant; the brief covers white and black cables.
