Cable length and connectors

This Jansicotek USB4 cable measures 3.3 feet and uses USB-C male connectors at both ends. The bi-directional, reversible plugs allow simple insertion either way. It is built with a braided jacket rated for 5,000 bend cycles in laboratory tests. An integrated E-Marker chip enables power negotiation up to 240 watts.

Use cases and limits

The cable suits owners of USB-C laptops, tablets, phones, Steam Deck, Switch, external SSDs or eGPU docks who need 40 Gbps data, 8K@60Hz or dual 4K@144Hz video, and up to 240 W charging. It also supports Thunderbolt 3 daisy-chaining of up to six devices. Buyers whose gear only reaches USB 3.2 or lower speeds will not gain the full bandwidth, and those needing a USB-A or DisplayPort connector must choose a different cable.

Deciding specification

The defining figure is the 40 Gbps USB4 Gen 3x2 data rate combined with 240 W (48 V/5 A) Power Delivery 3.1 support. If the host, charger and peripheral all meet USB4 Gen 3x2 and PD 3.1, the cable delivers maximum throughput and charging; otherwise performance falls back to the lowest common standard.

Questions about this item

Does the 40 Gbps data rate hold steady during long transfers to an external SSD?

The cable is rated for 40 Gbps under the USB4 Gen 3x2 standard and includes an E-Marker chip to maintain signal integrity, so sustained transfers to a compatible SSD should remain at the rated speed.

How warm does the cable get when delivering 240 W continuously?

The built-in E-Marker chip and 48 V / 5 A PD 3.1 support are designed to handle 240 W without excessive heat, and the braided jacket aids heat dissipation during all-day charging sessions.

What charger and host port are required to reach 240 W charging?

A USB-C PD 3.1 charger capable of 48 V / 5 A and a host device with a USB4 or Thunderbolt 3 port that accepts 240 W input are both needed to achieve the maximum power level.
