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

Does the 140W magnetic adapter generate noticeable heat during all-day charging?
