USB-C PD to 7.4×5.0mm barrel adapter

This compact converter lets you power a laptop that uses a 7.4mm by 5.0mm DC jack from any USB-C Power Delivery charger rated up to 100W. It is aimed at professionals and travellers who want to leave the original bulky power brick at home and carry a single lightweight USB-C charger instead. The adapter bridges the gap between modern PD sources and legacy barrel-input notebooks without requiring configuration.

Intelligent PD negotiation and reinforced connectors

An onboard PD negotiation chip automatically agrees the correct voltage and current with the connected USB-C charger, delivering stable output matched to the laptop’s requirements. High-quality internal wiring reduces resistive loss and heat during high-power sessions, while the reinforced barrel plug and USB-C socket resist looseness from repeated insertion. The rugged shell protects the circuitry during daily transport in a bag.

Replaces a proprietary laptop power brick

The adapter replaces the manufacturer’s dedicated AC adapter for any notebook that accepts power through a 7.4×5.0mm barrel port, provided a suitable USB-C PD source is available. The upgrade is worthwhile when you already own or prefer a compact multi-port USB-C charger and want to consolidate cables for travel or a minimal desk setup. It does not suit laptops with different barrel sizes, proprietary connectors, or power demands above 100W.
