Square port converter for Lenovo adapters

This cable adapts a Lenovo 11x5 square port power supply to a USB-C male connector. It accepts an input range of 19v to 22v and delivers up to 45W through negotiated profiles including 20v at 2.25A. The converter handles the voltage translation automatically so the laptop receives the correct power level.

Suits owners of compatible Lenovo square-tip

Users with a matching square plug adapter can repurpose it for USB-C charging without buying a new brick. Buyers whose power supply uses a different tip shape or who need more than 45W of output should look at other solutions. The cable does not work with barrel or slim tip connectors.

11x5 square female to USB-C male connector

The decisive spec is the 11x5 square female socket that mates only with the corresponding Lenovo adapter tip. If the charger has this exact square port the cable will connect; any other tip geometry makes the adapter unusable.
