DC 7.4 mm × 5.0 mm female input

This cable accepts a DC 7.4 mm × 5.0 mm female connector with a 0.6 mm centre pin and delivers up to 100 W of USB Power Delivery to a USB-C device. It suits users who want to power a laptop, phone or tablet from an existing DC brick instead of carrying the original charger.

Thermals noise and power draw

The braided nylon jacket and metal connector housings dissipate heat during high-current charging while keeping the 17.4 cm cable flexible. No active cooling is present, so operation stays silent and power draw matches the negotiated PD profile up to 20 V at 5 A.

Built-in PD identification chip

An automatic identification chip negotiates 5 V, 9 V or 20 V output with the connected device and prevents 12 V or 15 V from appearing on the USB-C plug. The 24-conductor pure-copper core supports USB 2.0 data at 0.48 Gbit/s for basic sync while charging.

Questions about this item

How do I connect the 7.4mm x 5.0mm female DC end to my power brick without damaging the laptop?

Insert the DC7450 female connector onto a 15V-20.5V DC brick rated above your laptop’s draw; the brick must exceed the laptop’s 100W limit or charging will not start.

Will the built-in PD chip or the braided nylon jacket need replacement after heavy daily use?

The PD identification chip and metal connector heads are fixed; only the 17.4cm braided cable might wear if bent sharply, so avoid tight coils.

At what power level does the cable stop negotiating higher voltage during a long charge session?

Negotiation caps at 20V 5A for 100W; it does not offer 12V or 15V steps, so sustained loads above 100W will not be supported.
