Two-Pack Magnetic USB-C Extenders

This Jansicotek LD240W two-pack provides detachable male-to-male USB-C extenders with 180-degree magnetic connectors. They add a breakaway safety point to Thunderbolt 3 and 4 or USB4 links while preserving full signal integrity for charging, data and video.

Sustained 240W Delivery and 40Gbps Throughput

The magnetic interface maintains a steady connection at up to 48 volts and 5 amps, allowing continuous 240-watt power delivery without thermal throttling. Data moves at the full 40 gigabits per second specified by USB4, and 8K video at 60 hertz remains stable during extended sessions.

240-Watt Power Delivery Rating

The single specification that decides fit is the 240-watt USB Power Delivery ceiling. If your host, cable and charger all support 240 watts, this extender passes the full rate; if any link in the chain tops out lower, the magnetic connector will simply negotiate the lesser available power.

Questions about this item

Does the 240 W magnetic extender run hot or draw extra power when used continuously all day?

The adapter is rated for 240 W (48 V / 5 A) and uses passive components only, so it adds no active cooling load and generates minimal heat during sustained use.

What must I already own to reach the advertised 40 Gbps and 8K 60 Hz performance with this extender?

You need a USB4 or Thunderbolt host, a certified USB4 cable, and a display or dock that supports 8K at 60 Hz.

Will the 180° magnetic connector work reliably with my existing Thunderbolt 3 dock and older USB-C cables?

Yes, the male-to-male design is backward-compatible with Thunderbolt 3 and standard USB-C cables, maintaining full mechanical and electrical connection.
