# kUSBPowerDuringWakeRevocable

The system requests power reallocation as revocable.

## Declaration

```occ
kUSBPowerDuringWakeRevocable = 6
```

## Discussion

Discussion The system uses this extra power while it’s awake, but the kUSBPowerRequestWakeRelease message can take that power away and reallocate it to another device.
