Purpose and Audience

The Jansicotek LD140W is a USB-C magnetic adapter that extends a Type-C port with a male-to-female connection. It is built for laptop users who need a detachable link that can handle high-power charging, fast data transfer and 8K video output in one compact device.

Sustained-Load Behaviour

The adapter is rated for up to 140W power delivery at 28V and 5A, maintaining that level continuously when paired with a compliant charger and cable. Its 24-pin gold-plated construction supports steady 40Gbps data throughput and 8K video at 60Hz without throttling during extended sessions.

Deciding Specification

The single figure that determines fit is the 140W power ceiling; if your device or charger cannot negotiate that wattage the adapter will still function but will not deliver its maximum charging speed.

Questions about this item
