Overview

The Dell 470-ACFG is a small adapter designed to bridge the gap between Dell's older 4.5mm barrel-tip power supplies and newer laptops and tablets that charge via USB-C. On one end it accepts a 4.5mm barrel connector (female), and on the other it outputs to a USB-C male plug. This means if you already own a Dell barrel-style charger and have upgraded to a USB-C powered Dell laptop, you can continue using your existing power adapter without purchasing a new USB-C charger.

The adapter is power-only and does not support data transfer or video output. It is built as a compact inline dongle that adds negligible weight and size, making it a practical addition to a laptop bag for travel or as a secondary charging option at a desk. Dell lists compatibility with notebooks and tablets, though users should verify that their specific USB-C Dell model supports charging through this adapter, as power requirements vary by device.
