Charging docks are a common accessory for PS4 controllers. While some use the standard micro USB port for charging, many of them make use of the EXT port, found next to the headphone jack.
I’ve created a small board, which makes use of the ability to charge the controller through this port.
Charging through this port is a great way to add a USB C port to your controller, without having to open the controller up or make any modifications to the controller shell.
In addition, it’s good for diagnosing damaged internal micro USB ports, by providing a second point through which to try to charge a controller.

Pick up an assembled board from our Ko-Fi store.
Board Design
The version of the board shown in this article can take either a micro USB port, or if you’d prefer, a USB C port. Footprints for both ports are included on the same board. An updated version of the board does not include the micro USB footprint, but is otherwise unchanged.
A jumper is included on the bottom of the board, which needs be soldered to the correct pad for the port you’re using. This is no longer present in the updated version of the board.
USB C needs to bridge the centre pad with the left-hand pad (labelled C), while micro USB makes use of the right-hand pad (labelled M).
If you’re using a USB C port, you might want to charge the controller using a smart charger. If so, you’ll want to populate the two resistors with 5.1k 0603 parts.
Completed Board
Here’s an example of a completed board, with a USB C port fitted.
In this case, the resistors are not fitted as it’s not used with a smart charger.
As a USB C port is used, the jumper is soldered on the right-hand side.
Plug the board into the EXT port, with the USB port facing upwards. The board has a snug friction fit into the port.
The controller will charge in the same way it would charge when using the built in micro USB port.
Where to Get One
If you’re looking for a pre-assembled board, you can pick one up from our Ko-Fi store. Note that we restock when required, and PCBs take a few weeks to get to us. If we’re out of stock, be sure to check back later as more will be on the way.
Dualshock 4 EXT Port Charger
Pick up an assembled board from our Ko-Fi store.
If you want to make one of these for yourself, you can find both the Gerber files, and KiCAD files, over on GitHub.
Dualshock 4 EXT Port Charging Board
Charge your Dualshock 4 using the EXT port with this board.
You should be able use the .zip file listed under ‘Releases’, and upload it to your PCB manufacturer of choice. I had these manufactured using OSH Park.
Due to the small size of the board, it’s not the easiest to solder the port in place without getting solder on to other parts of the board. Adding kapton tape to cover surrounding solder pads (particularly those that slot into the EXT port) is recommended.
