SKU CH-HFJE-A7T24

A replacement AC adapter delivering 20 V output with 100–240 V worldwide input and built-in over-voltage, short-circuit and over-current protection

  • World-wide 100-240 V input suits travel
  • 20 V output matches ThinkPad T440 requirement
  • Over-voltage, short-circuit and over-current protection built in
  • Includes detachable power cord for immediate use
  • New, tested unit backed by three-year service warranty

Compatible power supply for ThinkPad T440

This AC adapter replaces the original charger for Lenovo ThinkPad T440 models including 20B6005EUS, 20B6X007US and 20B6005RUS. It delivers 20V output for notebook and ultrabook power requirements. The unit includes the power cord cable for immediate use. Buyers needing a charger for a different ThinkPad series cannot use this adapter.

Continuous operation with worldwide input

The adapter accepts 100-240VAC at 50/60Hz for global mains compatibility. Built-in protection circuits guard against over voltage, short circuit and over current during sustained load. Output remains stable at 20V while powering the laptop and charging the internal battery. Users in regions outside the supported voltage range would need a different solution.

New unit with integrated cable and safety testing

Each charger is brand new and tested before shipment. The power cord is permanently attached to the adapter body, reducing loose connections during daily transport. Protective features are internal and require no user configuration. Customers who prefer a detachable IEC lead or a higher wattage rating for docking stations should consider other options.

Questions about this item

How much heat and noise does the 20 V adapter produce when powering a ThinkPad T440 all day?

The adapter has no moving parts and runs silently. It meets safety standards with over-voltage, over-current and short-circuit protection, so heat stays within normal limits for a 20 V supply.

Which cable or connector must I already have to connect this adapter to my ThinkPad T440?

A standard AC mains cord with a C7 figure-8 plug is included, and the DC tip fits the ThinkPad T440 rectangular port directly, so no extra cable is needed.

Will the 20 V output work with the original ThinkPad T440 battery and charging circuit I am keeping?

Yes. The adapter delivers 20 V, matching the voltage required by the T440 models 20B6005EUS, 20B6X007US and 20B6005RUS, so the existing battery and charging hardware operate normally.
