Purpose and fit

The iTekiro 65 W 20 V 3.25 A AC adapter supplies 20 V DC at 3.25 A for compatible Lenovo ThinkPad models including the P50s, P51s, S1 Yoga, S431, T431S, T440 and T440p. It accepts 100 to 240 V AC at 50 to 60 Hz for worldwide use and includes a 6 ft AC cord plus a 6 ft DC cord for extended reach.

Who it suits and who it does not

This unit suits owners of the listed ThinkPad models who need a direct replacement for a 45 W or 65 W genuine adapter and value the extra cord length for flexible desk or travel setups. It does not suit laptops that require a different output voltage, a higher current than 3.25 A or a proprietary connector not used by the models above.

Capacity and headroom

The adapter delivers up to 65 W continuous power, enough to run the supported ThinkPads and charge their batteries simultaneously whether the system is on or off. It will not meet the needs of larger workstations or gaming laptops that draw more than 65 W, and it cannot supply power over USB‑C or other interfaces not present on the listed models.
