Adapter Barrel to USB-C

Dell 7CY7K barrel-to-USB-C adapter connects a 7.4 mm barrel power source to a USB-C device input. It is intended for charging a notebook with USB-C power input from a readily available barrel-style power adapter.

The adapter has a 7.4 mm female DC jack and a 24-pin male USB-C connector. Dell lists rated voltages of 5 / 20 V and describes it for use with 45–65 W barrel power adapters, providing a compact link between these connector types.
