Does the PLT588 support fast charging for high-power laptops?

Yes. The PLT588 supports Power Delivery up to 240W (PD 3.1), making it suitable for large mobile workstations, gaming laptops, and docking setups that require sustained high-power charging under load.

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.

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.

Two specifications set it apart from the shorter cable in this range. The first is 240W: PD 3.1 raised the ceiling well above the older 100W limit, and it is what allows a single cable to run high-drain machines — large mobile workstations, gaming laptops and docking setups — that a 100W cable cannot keep 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.

Sustaining 40Gbps and 240W over 2 metres is why the construction is specified the way it is — polypropylene-woven with an aluminium shell — and why the E-Mark chip is not optional. E-Mark is the identification chip that tells the connected devices what the cable can actually carry; without it a high-power negotiation cannot safely take place.

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.
