Magnetic port protection

The Jansicotek LD240W is a straight USB-C magnetic adapter sold as a two-pack. It shields notebook ports from wear caused by frequent plugging and unplugging while keeping a secure connection through strong magnetic force.

Male-to-male USB-C with LED status

Each adapter uses a male-to-male USB Type-C gender changer finished in black. An integrated LED indicator confirms the link is live, and the package includes two small cord straps for cable management.

240W power delivery with 40Gbps data

The adapter supports USB4 and Thunderbolt 3/4 at up to 40Gbps and delivers up to 240W of power. It also carries 8K video at 60Hz for external displays. Buyers who need a right-angle connector or a female port on one end cannot use this design.
