Ruth's sister USB-C PD to Dell 7.4×5.0 mm 65 W 87 W Power Cord

Dell 7.4 × 5.0 mm PD trigger cable

This adapter cable lets a USB-C Power Delivery charger power Dell laptops that use the 7.4 × 5.0 mm barrel connector. A built-in PD emulator chip negotiates 20 V output from a compatible 65 W or 87 W Type-C supply. It suits owners of compatible Dell Latitude models who want to replace a bulky proprietary brick with a single USB-C charger. Buyers whose laptops require a different barrel size or voltage cannot use this cable.

USB-C PD input to 20 V barrel output

The Type-C female port accepts a PD charger capable of 65 W or 87 W at 20 V and converts it to the Dell-specific DC plug. The cable only works when the source charger supports the required PD profile; standard 5 V or 9 V phone chargers will not trigger the 20 V output. No additional driver or software is involved, but the source must explicitly provide 20 V PD power. Builders needing to power non-Dell devices or multiple voltages should look elsewhere.

Replaces proprietary Dell 65 W or 87 W AC adapters

This cord replaces the original Dell 65 W or 87 W barrel-type power supply for supported Latitude notebooks. The jump is worthwhile when you already carry a high-power USB-C PD charger and want to reduce the number of bricks in your bag. It does not increase charging speed beyond what the laptop and PD source already negotiate. Users who need simultaneous charging of other devices from the same PD charger must verify the charger's total power budget themselves.
