Slim-tip square adapter for USB-C devices

This 17.4 cm cable converts a slim-tip square female input into a USB Type-C male output. An integrated PD automatic-identification chip negotiates power delivery at 5 V, 9 V or 20 V up to 140 W. The copper core is wrapped in a nylon-braided jacket with metal connector housings for durability.

Users with square-tip power bricks below 140 W

The adapter suits owners of square-tip chargers rated above the laptop’s draw who want a compact USB-C charging lead for phones, tablets or laptops. It will not work if the brick is 90 W or 100 W and the device requires equal or higher power. Buyers needing longer reach or higher wattage should look elsewhere.

140 W PD limit with 20 V 7 A output

The built-in chip caps output at 20 V and 7 A, delivering a maximum of 140 W with no 12 V or 15 V steps. Input voltage must fall between 15 V and 20.5 V, and the source brick must exceed the device’s power requirement for the cable to function.
