# Powering options

## USB-C Power Distribution (PD) charger

WLAN Pi R4 can be powered by USB PD power supply. We highly recommend using Raspberry Pi 4 Revision 1.2 or newer, which supports all USB PD power supplies including MacBook USB-C chargers.

To check your revision, SSH to the RPi4 and execute:

```
cat /proc/cpuinfo
```

## USB-C port of your laptop

WLAN Pi R4 can also be powered by USB-C port of your laptop using USB-C to USB-C cable.

Some older laptops might not be able to provide enough power via USB. Please double-check.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://userguide.wlanpi.com/hardware/wlan-pi-r4/powering-options.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
