What this cable does and who needs it

The eForChina DC5.5x2.5mm cable converts a USB Type-C 140W Power Delivery source into a barrel-style DC output for laptop charging. It accepts 140W, 130W, 100W or 65W input and delivers up to 20V 7A through the selected tip. A built-in PD3.1 Emark decoy chip handles power negotiation and provides overload protection. The 1.8m nylon braided cable is designed for daily carry and plug-and-play use.

What to verify on your laptop before ordering

You must confirm the exact barrel dimensions your laptop requires. The package includes interchangeable tips measuring 4.5x3.0mm, 7.4x5.0mm, 5.5x2.1mm, 5.5x2.5mm and 6.0x3.7mm. Only one of these will fit your device. Using an incorrect tip can prevent charging or cause damage. The source charger must also support the required Power Delivery profile to reach the desired output wattage.

How it fits into your charging setup

This adapter replaces a proprietary laptop brick with a standard USB Type-C PD charger you may already own for other devices. It frees you from carrying the original bulky power supply when travelling. The cable needs a compatible PD charger rated for the wattage your laptop draws. It does not add power; it only passes what the source provides through the selected DC tip.

The cable includes five DC tips — 4.5×3.0 mm, 7.4×5.0 mm, 5.5×2.1 mm, 5.5×2.5 mm and 6.0×3.7 mm — and requires a USB-C PD charger that can deliver up to 140 W; the charger is not included.

Which DC tip should I select for my laptop?

What does the 140 W rating mean when I plug this into my laptop?

The cable can pass up to 140 W (20 V / 7 A) from a compatible PD3.1 charger to your laptop, provided the charger and laptop both support that power level.
