DC converter cable for Dell and HP ultrabooks

This cable adapts a 7.4mm female barrel connector to a 4.5mm male pin connector. It is designed for owners of specific Dell XPS and HP EliteBook, Pavilion, Envy and Chromebook models who need to use a power supply with the larger plug. The single converter cable enables direct connection without an intermediate adapter block.

Check your laptop power port and charger tip

Verify that your laptop requires a 4.5mm pin input and that your existing charger provides a 7.4mm female output. The connector dimensions are 7.4mm by 5.0mm on the female side and 4.5mm by 3.0mm on the male side. Matching these exact measurements is essential for a secure fit and correct polarity.

Cable-only design keeps the kit minimal

The package contains one converter cable and no additional accessories or software. There is no voltage regulation or active circuitry inside the cable. It simply passes power through from the charger to the laptop, so the original power supply must already deliver the correct voltage and current for the target device.
