Two-pack magnetic USB-C adapter

This two-pack supplies a male-to-female USB-C magnetic adapter rated for USB 4 and Thunderbolt 3/4. Each unit adds a quick-release magnetic connection that protects ports from strain while passing power, video and data through a single compact elbow body.

140 W charging headroom and limits

The adapter negotiates up to 140 W (28 V / 5 A) Power Delivery and can pass 240 W maximum through the magnetic interface. It automatically adjusts output to the attached device, so a 60 W laptop charges at 60 W while a 140 W machine receives the full rate. The 20 Gbps data ceiling matches USB 4 20 Gbps, not the 40 Gbps tier.

USB 4 20 Gbps and 8K video boundaries

Video output reaches 8K at 60 Hz over the 24-pin gold-plated connector set. Bandwidth tops out at 20 Gbps, which covers dual 4K or single 8K streams but leaves no headroom for simultaneous peak storage traffic. The magnetic latch releases under cable tug, preventing port damage but limiting use where a locking screw connection is required.
