# 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.
