A design that is compliant with the USB-C specifications will work with e-marked USB-C cables ( more info) unfortunately, the Raspberry Pi 4 will not. Or perhaps, The Foundation simply wanted to sell more of their "official" power supplies for the RPi 4B?Īnd so despite the fact that the Macbook Pro 87W USB-C Power Adapter ( now replaced by the 96W supply) has more than ample power to handle the RPi 4, the RPi 4 is missing hardware that allows it to work with e-marked USB-C cables. This has been reported in several sources, including this post on TechRepublic, this post on Hackaday, and further analyzed in this post by Tyler Ward. HOWEVER., it seems that the Raspberry Pi designers didn't read the USB-C specs, and didn't test their design very well before releasing it to production. The specifications printed on the adapter state that its 5.2 volt output is rated at 2.4 Amps. The Macbook Pro 87W USB-C Power Adapter has enough power to run the RPi 4B. It will not damage your RPi, but it won't work unless you use a NON e-marked USB-C cable ( details follow). EDIT NOTE: This is a revised answer as my original answer was wrong! Revised Answer:
