The Raspberry Pi 4 launched in late June and as usual, it's a major upgrade over the prior model, packing more RAM, enough graphics horsepower to drive a pair of 4K displays, and USB-C charging instead of micro-USB. The Raspberry Pi Foundation confirmed to TechRepublic that the single-board computer won't work with some cables. One of those ways is power through a standard USB-C connector to allow for the extra bit of juice the beefier board needs compared to its older brother.
It all boils down to the type of cable you use.
As a result, the smart USB-C chargers, also known as electronically marked or e-marked USB-C chargers, will not supply any power to the board.More news: Oil gains after USA stockpiles drop, rigs evacuated
Compatibility woes are nothing new with USB-C, but in this case, the problem lies with the Pi. Fully compliant ones used by higher voltage devices like laptops will identify the Raspberry Pi 4 as an audio device and won't power it.
An easy workaround is to buy a non-e-marked cable or charger.

Instead of trying to come up with some clever circuit", Leung writes, "hardware designers should simply copy the figure from the USB-C Specexactly [emphasis his] The Figure 4-9 I posted above isn't simply a rough guideline of one way of making a USB-C receptacle.
The Raspberry Pi Foundation isn't the only one to have flubbed this up. The Raspberry Pi Foundation will probably fix this design error in future board revisions, so you might get a more compatible device if you wait for that. You can count on non-e-marked cables, including the ones that near with many smartphones as successfully because the loyal Raspberry Pi possibility.
"It's surprising this didn't show up in our (quite extensive) field testing program", Upton said. It's actually normative, meaning mandatory, required by the spec in order to call your system a compliant USB-C power sink.

We reached out to Raspberry Pi about this issue and were told a board revision with a spec-compliant charging port should be out sometime in the "next few months". The good news is, the official Raspberry Pi power supply does work.
