  • ColorBlack
  • Thunderbolt 3Yes
  • Terminal GenderMale to Male
  • Apple CompatibleUSB-C port

Cable Length 5 Feet

Model USB4

  • Charges up to 240W with PD 3.1
  • Transfers data at 40 Gbps via USB4
  • Drives one 8K 60Hz or dual 4K 60Hz displays
  • Works with Thunderbolt 3 and 4 devices
  • Built-in safety resistor limits current to 5A

What this cable does

This LUOM USB4 cable carries 40 Gbps data, delivers up to 240 W at 48 V 5 A, and drives a single 8K 60 Hz or dual 4K 60 Hz display over a 3 ft male-to-male USB-C link. It is backward compatible with Thunderbolt 3 and 4 hosts and with USB 3.2, 3.1, 3.0 and 2.0 devices.

Who it suits and who it does not

Professionals who need maximum USB4 bandwidth, 240 W charging for laptops or power tools, and multi-monitor 8K or 4K video from one cable will benefit. Buyers whose devices only support lower USB-C power or video modes, or who require a longer cable than 3 ft, will not gain the advertised performance.

The deciding specification

The single figure that determines whether this is the right part is the 40 Gbps USB4 Gen 3x2 data rate combined with 240 W PD 3.1 power delivery; both the host and the peripheral must support these specifications to achieve the stated speed and charging levels.

Questions about this item

How long before the USB-C connectors or internal E-marker chip need replacement under daily 240 W charging?

The cable uses standard USB-C male connectors rated for thousands of mating cycles; no user-replaceable parts exist, so the entire cable is replaced only if a connector is physically damaged.

What limits sustained 40 Gbps transfers during hours-long backups — thermal throttling or the 5 A current ceiling?

The built-in safety resistor caps current at 5 A, so the first limit under continuous load is the 5 A ceiling rather than connector heating.

Does the cable become noticeably warm or draw extra power when driving dual 4K 60 Hz displays all day?

Power delivery and video signalling share the same conductors; the cable stays within the 5 A design limit, so warmth remains low during all-day dual 4K 60 Hz use.
