What this cable delivers

The StarTech S2CEPR2M-USBSL-CABLE is a 2m USB-C to USB-C charging cable rated for 240W Power Delivery 3.1 EPR at 48V with 5A current. It carries USB 2.0 data at 480Mbps and includes an integrated E-marker chip for certified power negotiation. Screw-locking connectors on both ends secure the link in vibration-prone setups such as drive enclosures or mobile workstations. Backward compatibility covers 140W, 100W and 60W profiles.

Installation and common issues

Knurled M2 side screws tighten by hand for a firm lock without tools, and the nickel-plated contacts are rated beyond 10000 insertions. The dual-layer braided nylon jacket withstands +/-90° bends and 20000 flex cycles, reducing cable fatigue in tight routing. The only frequent snag is forgetting to align the screw threads before pushing the plug home, which can cross-thread the lightweight M2 hardware. USB-IF certification ensures the E-marker communicates correctly with compliant hosts and chargers.

Who should buy and who should not

This cable suits users who need a rugged, high-wattage link for 16in MacBook Pro or similar USB-C PD laptops, plus anyone securing connections on external storage or docks that expose side-locking ports. It is not for buyers who require USB 3.x or higher data throughput, since the cable tops out at USB 2.0 480Mbps. It also does not fit devices lacking the side-screw receptacle, so standard USB-C ports without locking threads cannot use the locking feature.

Questions about this item

How can I confirm the cable is delivering the full 240W after connecting it?

The connectors carry performance markings for easy identification, and the integrated E-marker chip enables the host device to negotiate the 240W PD 3.1 EPR contract automatically.

What accessories are included in the box and what must I provide separately?

The package contains the 2m USB-C to USB-C cable with M2 screw-locking connectors; a compatible PD 3.1 charger and a device with a side-locking USB-C port are required separately.

When should I choose this 2m screw-locking version over a standard non-locking cable?

Select this model when the charger, hub or drive enclosure has side-locking USB-C ports and a secure, vibration-resistant connection is needed for 240W PD 3.1 EPR charging.
