USB4 40Gbps/240W Cable 2m - PLT588

Name: USB4 40Gbps/240W Cable 2m - PLT588
Brand: Tonetron
SKU: PLT588

2m USB4 cable, 40Gbps, 240W PD 3.1 and DP1.4 video to 8K@60Hz, Thunderbolt 4 compatible with E-Mark chip; charging power depends on the charger and laptop both supporting and negotiating the corresponding USB PD EPR mode. Actual data speed, video output and interoperability with Thunderbolt devices depend on the shared capabilities of the host and connected devices.

Overview

The PLT588 is a 2 metre USB4 cable rated at 40Gbps, carrying DP1.4 video up to 8K@60Hz and Power Delivery up to 240W under PD 3.1, with an E-Mark chip and Thunderbolt 4 compatibility. Actual data speed, video output and interoperability with Thunderbolt devices depend on the shared capabilities of the host and connected devices. For 8K@60Hz, verify that the host, display and any dock or adapter support the required video mode.

Two specifications set it apart from the shorter cable in this range. The first is the stated power rating of up to 240W under USB PD 3.1. Actual charging power depends on the modes supported and negotiated by the charger and laptop; reaching 240W requires both to support the corresponding Extended Power Range (EPR) mode. The cable rating alone does not guarantee that a high-drain laptop stays charged under load. The second is 2 metres, which is what makes a desk setup practical: reaching a docking station on the floor, a monitor at the back of a desk, or a sofa from a wall socket.

This page lists a polypropylene-woven construction and an aluminium shell. These material descriptions alone do not demonstrate 40Gbps signal performance or 240W power delivery over 2 metres. The E-Mark chip communicates the cable's declared capabilities to connected devices; its presence alone does not replace model- and length-specific signal integrity and power delivery test evidence. Request the relevant test reports when qualifying this cable.

Where the requirement is a short, highly flexible cable rather than maximum power, the 0.8m PF587A in this range covers 40Gbps and 100W in a moulded TPE build.

Branding and packaging are customisable for OEM/ODM orders.

Frequently Asked Questions

Does the PLT588 support fast charging for high-power laptops?: The specifications on this page rate the PLT588 for USB PD 3.1 power delivery up to 240W. Actual charging power depends on the modes supported and negotiated by the charger and laptop; reaching 240W also requires both to support the corresponding USB PD 3.1 Extended Power Range (EPR) mode. The cable alone cannot make a laptop accept 240W or guarantee that its battery stays charged under load. Check the laptop's USB-C charging specifications and the charger's output before selecting the cable.
Is the E-Mark chip included, and why is it important?: Yes, the PLT588 includes an E-Mark chip. This identification chip communicates to connected devices what the cable can safely carry, ensuring high-power negotiation occurs correctly and safely.
What video and bandwidth specs does this cable support?: The PLT588 delivers 40Gbps bandwidth, DP1.4 video output up to 8K@60Hz, and is fully Thunderbolt 4 compatible.
Can we customize branding and packaging for bulk orders?: Yes. Tonetron offers OEM/ODM customization of branding and packaging for wholesale and distributor orders.
Why is the 2m length with polypropylene weaving and aluminium shell specified?: Sustaining 40Gbps and 240W over 2 metres requires robust construction; the polypropylene weaving and aluminium shell protect signal integrity and power delivery over the longer distance for practical desk setups.
