Dell Kit - Type C Dongle (7.4mm) (0684H) - USB-C to 7.4mm DC Power Adapter Cable

When you're on the road with your Dell laptop and realize the original power brick is too bulky to carry, this compact dongle steps in. It lets you use a standard USB-C PD charger to power a Dell laptop that has a 7.4mm DC barrel port. Just plug the USB-C end into a compatible charger or power bank, and the 7.4mm plug into the laptop. It's a simple, lightweight solution for travellers, remote workers, or anyone who wants to reduce cable clutter.

Why choose it

This dongle eliminates the need to carry a dedicated Dell AC adapter. If you already have a USB-C PD charger for your phone or tablet, you can use it to power your laptop. It's a cost-effective and space-saving alternative to buying a second OEM power brick. The short cable keeps things tidy, and the durable PVC housing withstands daily use.

Ideal use cases

• Travel: pack it with your USB-C charger instead of a heavy laptop adapter.
• Home office: use a single USB-C charger for multiple devices.
• Backup power: keep one in your bag in case the original adapter fails.
• Workspace decluttering: replace bulky power bricks with a sleek USB-C setup.

Good to know

Make sure your USB-C charger supports USB PD and can deliver at least 45W for most Dell laptops; for higher-end models, 65W or 100W is recommended. The dongle is designed specifically for Dell laptops with a 7.4mm DC input. It is not compatible with laptops that use USB-C charging directly or other barrel sizes. Always verify your laptop's power requirements before use.
