USB-C to 11.0 x 4.5 mm rectangle trigger cable

This cable converts a 65 W USB-C power delivery charger into a DC 18-20 V source for laptops that use a rectangular 11.0 by 4.5 mm barrel connector. It is intended for users who want to power or charge compatible notebooks from a single compact wall adapter.

PD emulator built into the Type-C female end

The integrated trigger negotiates the required voltage automatically when a capable charger is connected. The rectangular male plug fits the laptop's DC input directly, while the Type-C female port accepts the charger cable; the charger's rated power must meet or exceed the laptop's demand.

Delivers 18-20 V from a 65 W PD source

The cable passes the negotiated 18 V or 20 V output without supporting 5 V operation. Power draw and thermal load are determined by the attached charger and laptop, so normal use stays within the limits of the 65 W PD supply.

Questions about this item

What USB-C power standard does the cable’s built-in PD trigger require, and what voltage does it deliver to the rectangular tip?

The cable negotiates USB Power Delivery with a 65 W Type-C charger and outputs a fixed 18-20 V DC to the 11.0 × 4.5 mm rectangular connector; 5 V is not supported.

What are the exact dimensions of the rectangular DC plug that must match the laptop’s power jack?

The output plug is a rectangular male connector measuring 11.0 mm by 4.5 mm, designed for laptops that accept a DC 18-20 V barrel-style jack of that size.

How do I connect the cable so the PD trigger activates, and what common mistake prevents charging?

Plug a 65 W or higher USB-C PD charger into the cable’s Type-C female end, then insert the rectangular tip into the laptop; using a charger rated below 65 W will not trigger the required voltage.
