What this cable does and who uses it

This two-pack of USB-C to USB-C cables delivers up to 100W of power for fast charging phones, tablets and laptops. Each cable is 3.3ft long and includes an E-marker chip with a 56K ohm resistor to stabilise current and voltage. The set suits anyone needing spare or replacement charge leads for multiple USB-C devices. It does not support video output, so buyers who want display connectivity should look elsewhere.

Thermals noise and power draw

The cables carry up to 100W (20V at 5A) when paired with a compatible charger, and the built-in E-marker chip regulates power flow to prevent overheating. No active cooling or moving parts are present, so operation is silent. Actual charging speed depends on the power adapter and the device being charged.

The spec that decides fit

The critical detail is the lack of video or data-transfer support beyond basic charging; these are power-only cables. If you need a lead that can drive a monitor or move files at high speed, this pack will not meet that need. For pure charging across a wide range of USB-C gear, the 100W rating and dual-cable value make it a practical choice.

Questions about this item

How do I connect the 3.3ft USB C to USB C cable to my MacBook Pro 2020 for 100W charging?

Plug one USB-C end into the MacBook Pro 2020 port and the other into a 100W USB-C power adapter; the built-in E-Marker chip and 56K ohm resistor negotiate 20V 5A automatically, but the charger must supply 100W for full speed.

What part of the cable wears out first with daily plugging and unplugging?

The USB-C connectors are the primary wear point; the E-Marker chip and 56K ohm resistor are sealed inside the plug moulding, so only repeated insertion cycles can degrade the contact pins over time.

At what power level does the cable hit its thermal limit during a long charging session?

The cable is rated for 100W (20V 5A) continuous delivery; the E-Marker chip regulates current to stay within that ceiling, so sustained loads at or below 100W will not exceed the design thermal limit.
