Microsoft describes the Surface 140W USB-C Power Adapter as a power source for compatible USB-C charging devices. The adapter's detachable USB-C cable is sold separately, and the support page recommends a cable rated for five amps. The cable is therefore a separate part of checking the charging arrangement.

Compare the device's requirements with the adapter and the specific lead being used, rather than assuming the connector alone guarantees the intended result. Microsoft also recommends genuine or licensed charging accessories. Follow the device's charging and safety guidance when assembling a replacement setup or using the adapter with another supported device.
