Raspberry Pi Foundation has supported the It has a flaw in the USB-C design for its new Raspberry Pi 4 boards. They hope to solve it in the future, but for now, those who buy a Raspberry Pi 4 will have no solution and will have to deal with this failure with no alternative. It seems that this big update to the Pi board has been clouded a bit with this problem, but you have to trust them and wait to see what solution they give you, without going into hysteria.
You already know that one of the peculiarities of this SBC Raspberry Pi 4 board is a more powerful CPU, up to 4GB of RAM, a modern USB-C for power, etc. Well, it is precisely that modern USB-C that is the source of problems. The first foundation plate with this type of connector and they have flawed in design as detailed by Tyler Ward. And is that loading port it doesn't support USB-C like it should.
Many chargers don't work for this board, and that's a problem. Tyler Ward was able to spot it thanks to the open nature of the SBC board, as the schematics are on the internet. Ward could see from them that the developers just didn't design their port correctly. Be supposed to two DC pins have their own 5.1K ohm resistor, but they have created a design in which they share a single resistance.
That design is not compatible with modern powerful USB-C chargers. All the chargers marked E, which are the modern ones with internal chips for energy management, are the ones that generate problems. So avoid those chargers. With the others there is no problem, but those when connecting the Pi detect it as if it were an audio adapter and therefore do not supply power. So ... you should hope that with the new revisions of the board it will be solved, but for now it's time to hold on ...
