Apple’s AR headset has been reported to tout computing performance similar to the company’s M1 chip. However, that will require a decent power delivery to the device, and according to a renowned analyst, the same 96W power adapter that comes bundled with the 2021 MacBook Pro will be used.

New information from TF International Securities Ming-Chi Kuo states that to deliver the computer performance of Apple’s upcoming AR headset, it will need a 96W power adapter. MacRumors reports that it is the same power brick that comes with the 2021 14-inch MacBook Pro, but the smaller portable Mac actually ships with a 67W adapter, not 96W, though it is still compatible with the bigger one.
