Vszerda PD 100W 18.5-20V Square Plug to USB-C Adapter Nylon Braid Cable 9cm

SKU CH-C23N-WRNTH

A 9 cm cable converts an 18.5–20 V square plug to USB-C for 100 W PD charging from a power bank or wall charger

  • Delivers up to 100 W power via USB-C PD
  • Accepts 18.5-20 V input from square-plug sources
  • Connects square-plug chargers to USB-C devices
  • 9 cm braided cable reduces clutter
  • New condition ensures reliable performance

Square-plug power adapter for USB-C charging

This 9 cm cable connects a square-barrel power source to any device with a USB-C Power Delivery input. It is intended for users who want to run or charge a USB-C laptop, tablet or phone from an existing 18.5–20 V brick or compatible power bank.

Simple plug-and-play connection

No drivers or configuration are required; the adapter passes power directly from the square plug to the USB-C end. The only common issue is attempting to use a source that cannot supply the 100 W PD profile, which will result in no charging or very slow charging.

Limited to 100 W USB-C Power Delivery

The cable supports up to 100 W over USB-C PD and accepts 18.5–20 V input. It cannot deliver more than 100 W, cannot negotiate higher voltages, and will not work with proprietary barrel-charger protocols that fall outside the PD specification.

Questions about this item

How do I verify the adapter is delivering the rated 100 W after plugging it in?

Connect the square plug to the device and the USB-C end to a PD charger; the device should show it is receiving 100 W and charge at full speed.

What comes in the package and is anything else required?

The box contains only the 9 cm nylon-braided square-plug-to-USB-C cable; a compatible USB-C PD charger or power bank must be supplied separately.

Which voltage version should I choose for an 18.5 V or 20 V laptop?

This single model covers the 18.5–20 V range, so it works with either voltage without needing a different variant.
