Dell USB-C to 7.4 x 5.0 mm DC Adapter
This adapter converts a USB-C Power Delivery source into a 7.4 mm by 5.0 mm barrel connector with a .6 mm centre pin. It is designed for owners of compatible HP EliteBook and tablet models who want to replace a proprietary power brick with a standard PD charger. The unit supports up to 100 W and automatically negotiates the required voltage and current.
Build Integration and Cable Freedom
A USB-C PD charger rated for the laptop’s original wattage is required; the adapter itself adds no bulk and weighs only .02 kg. It eliminates the need to carry the original barrel-style AC adapter, freeing bag space and allowing a single PD charger to power both the laptop and other USB-C devices. No video or data signals pass through the connector.
Upgrade Context and When It Is Worth It
This replaces the factory barrel-type power supply for the listed HP models ranging from the 2530p and 2730p through the 8770w series. The jump is worthwhile when the original brick is lost, damaged or simply too heavy for travel, and a suitable PD charger is already owned or planned. It cannot be used with laptops that require a different barrel size or that do not accept power over USB-C.
