This angled adapter has a female 2.1mm barrel jack socket on one end and a male USB-C connector on the other, ideal for powering your Raspberry Pi 4 from a 5V 2.1mm DC power supply. It's the angled version of our straight USB-C to barrel jack adapter, good for scenarios that require cables to be lost quickly to the side.
This adapter will pass whatever voltage you put into the barrel jack end, so when using with a Raspberry Pi you MUST ensure it's a well-regulated 5V power supply. The barrel jack has a centre-positive tip.
You can of course use it for any other device that uses a USB-C connection too!
