SKU CH-223D-KMTJ4

  • Connects 5.5 mm × 2.5 mm chargers to square-pin ThinkPad X1 ports
  • 15 cm length keeps internal routing tidy
  • Male-to-female design converts the plug without extra bulk
  • New condition ensures reliable contact from first use

Lenovo ThinkPad X1 Power Adapter

This 15 cm cable converts a 5.5 mm by 2.5 mm male DC plug into a square female connector for the Lenovo ThinkPad X1. It lets owners power the laptop from a compatible barrel-type source without replacing the original charger. The short length keeps cable routing tidy inside a bag or on a desk. It is a direct replacement for a lost or damaged converter.

Passive connector with no active electronics

The adapter draws no power of its own and adds no fan noise or heat to the system. Voltage and current pass straight through from the supply to the laptop. Normal use produces no audible sound and no measurable temperature rise. It simply bridges the two connector shapes.

Questions about this item

How do I connect the 5.5mm x 2.5mm male plug to my Lenovo ThinkPad X1 charger, and what is the common mistake?

Plug the 5.5mm x 2.5mm male end into the charger tip, then insert the square female end into the laptop; the step often missed is pushing the square connector fully until it clicks.

Will the 15cm cable or its connectors need replacement over time?

The 15cm adapter cable has no moving parts; only the square female port or the 5.5mm x 2.5mm male plug may wear after repeated insertions, requiring a new adapter.
