USB-C 140W charging cable for laptops

This 1.8m cable connects a USB-C Power Delivery source up to 140W to a laptop with a DC barrel jack. It includes a built-in PD3.1 Emark decoy chip for intelligent charging and overload protection. The nylon braided jacket adds wear resistance for daily transport. Plug-and-play operation requires no drivers or configuration.

Suits owners of compatible barrel-jack laptops

Buyers whose laptop uses one of the listed DC tip sizes and who have a 140W, 130W, 100W or 65W USB-C PD charger can use this cable. It is not for laptops that charge only via proprietary connectors or require a different barrel diameter. Users without a sufficient USB-C PD power source will not achieve the rated output.

DC tip selection determines compatibility

The adapter ships with five interchangeable tips: 4.5x3.0mm, 7.4x5.0mm, 5.5x2.1mm, 5.5x2.5mm and 6.0x3.7mm. Matching the exact tip to the laptop's DC port is the single specification that decides whether this cable works. An incorrect tip prevents connection regardless of power capability.

Questions about this item

How do I connect the Type-C end to a 140 W PD charger and which DC tip fits my laptop port?

Plug the USB-C connector into a charger that delivers 140 W PD (also works with 130 W, 100 W or 65 W), then snap on the tip that matches your laptop's DC jack — options are 4.5x3.0 mm, 7.4x5.0 mm, 5.5x2.1 mm, 5.5x2.5 mm or 6.0x3.7 mm.

Will the nylon-braided cable or the built-in PD3.1 Emark chip need replacement after heavy use?

The 1.8 m nylon-braided cable is designed for wear resistance, and the Emark decoy chip handles intelligent charging and overload protection; neither component has a stated service interval, so no scheduled replacement is required.

What stops me from drawing the full 140 W continuously through this adapter?

Sustained 140 W output is only possible when the source charger also supplies 140 W PD; with a 130 W, 100 W or 65 W charger the cable will limit power to that lower level.
