Dell Barrel to USB-C Adapter β 7.4mm Barrel Connector
The Dell barrel to USB-C adapter is the official Dell accessory. It converts a USB-C Power Delivery power supply output to the 7.4mm barrel DC connector used on compatible Dell laptops. Dell laptops in the Latitude, Inspiron and Vostro ranges have used the 7.4mm barrel connector as their charging inlet for many years. This format requires a Dell-proprietary barrel charger for direct charging. The Dell barrel to USB-C adapter changes this by converting any compatible USB-C PD power supply β from a laptop charger, a USB-C hub with PD or a USB-C power bank β into a source that charges the Dell barrel-connector laptop correctly.
The practical benefit of the Dell barrel to USB-C adapter is flexibility. When travelling with a USB-C device and a Dell barrel-connector laptop, a single USB-C PD charger can serve both devices through the adapter. This reduces the number of chargers in a travel bag. At a desk, any USB-C PD charging source can be used for the Dell laptop without requiring the original Dell barrel charger. As an official Dell accessory, the Dell barrel to USB-C adapter is designed and tested for compatibility with the Dell 7.4mm barrel connector standard and the Dell power management system.
Compatibility Verification
Always verify your Dell laptop uses the 7.4mm barrel connector and that your USB-C PD supply meets the laptop’s wattage requirement before using the Dell barrel to USB-C adapter. Insufficient wattage results in slow or no charging. Using a lower-wattage USB-C supply than the laptop requires may result in slow charging or no charging under load.
