65 W AC adapter for ThinkPad

This 65 W AC adapter delivers 20 V at 3.25 A to a wide range of ThinkPad models including the Yoga 13, X1 Carbon, Flex 14, T430, T440 series, T450, T460 series, T470 series, T540P, T560, E440, E450, E550, E560, Z50 and G50. It accepts a universal 100–240 V input at 50–60 Hz for worldwide use.

Steady output under continuous load

The unit maintains its rated 65 W output during extended charging sessions without dropping voltage or triggering thermal protection. It is designed to sustain the 20 V, 3.25 A specification for the duration of a typical workday rather than only in short bursts.

Compact brick with fixed cable

The adapter body is sized to sit unobtrusively on a desk or travel bag and the integrated DC cable ends in the rectangular ThinkPad connector that fits the listed part numbers 5A10J40449 and PA-1650-72. Users needing a USB-C power source or a detachable mains lead will not find those features here.

Questions about this item

Does the 65 W 20 V 3.25 A adapter run hot or make noise when powering a ThinkPad T470 all day?

The unit delivers a steady 20 V at 3.25 A from a 100-240 V 50-60 Hz supply with no moving parts, so it stays cool and silent during continuous use.

Which cable or connector must I already have to plug this 65 W adapter into my ThinkPad X1 Carbon?

The adapter terminates in the standard Lenovo 20 V rectangular tip used by Yoga 13, X1 Carbon, Flex 14, T430 through T470S, E440 through E560, Z50 and G50 models.

Will this 65 W 20 V charger work alongside the original 45 W brick I kept for my older ThinkPad T440s?

Yes — both units output 20 V and share the same tip, so the 65 W model safely replaces or supplements the 45 W brick on any listed ThinkPad.
