USB-C to 4.5 mm Smart Tip cable

This 1.8 m cable connects a USB-C Power Delivery source to Dell Inspiron laptops that use a 4.5 mm barrel connector. It supports 45 W, 65 W and 90 W profiles when the PD charger supplies 20 V at 3.25 A or 5 A respectively. The nylon-braided jacket and reinforced joints resist tangling and wear during daily transport.

Thermals noise and power draw

The cable itself generates no heat or noise; all power conversion occurs inside the PD charger you pair with it. Voltage drop over the 1.8 m length is minimal, so the laptop receives the full 20 V required for 45 W, 65 W or 90 W operation. No active cooling or fan is involved in the cable assembly.

Bundled accessories and software

No software, drivers or additional adapters are included in the package. The only item supplied is the USB-C to 4.5 mm smart-tip cable. Users must provide a compatible USB-C PD charger or power bank capable of 20 V output at the required current for their laptop model.

Questions about this item

How do I connect the 4.5mm smart tip cable to my Inspiron 5558 using a USB-C PD charger?

Plug the USB-C end into a PD charger that delivers 20V at 3.25A for 45W or 65W, or 20V at 5A for 90W, then insert the 4.5mm tip firmly into the laptop's charging port.

Will the nylon braided 1.8m cable need any periodic maintenance or tip replacement?

The reinforced joints and nylon braid are built for long life; no scheduled maintenance is required, but inspect the 4.5mm tip occasionally for debris or bent pins.

What power limit will I hit first if I run an Inspiron 7568 continuously on a 65W PD source?

The cable supports up to 65W at 20V 3.25A, so the PD charger's 65W ceiling is the first limit reached under sustained load.
