65W AC adapter for Lenovo IdeaPad and Yoga

This 65W AC adapter delivers 20V at 3.25A through a 4.0 x 1.7 mm connector. It supports a wide range of Lenovo IdeaPad 1, 3, 5, Flex and Yoga models, plus select Chromebook N22, N23 and N42 devices. The unit also covers 45W 20V 2.25A requirements for compatible systems. It is intended for users replacing a lost or damaged original charger.

Universal 100-240V input for worldwide use

The adapter accepts AC 100-240V at 50 or 60Hz, allowing operation on mains supplies around the world without a voltage selector. Normal use draws up to 65W from the wall, matching the output rating. No thermal, noise or efficiency figures are provided by the supplier, so typical operating temperature and acoustic profile cannot be stated.

Detachable mains lead included for regional plugs

A detachable IEC C7 mains cable is supplied, letting the user fit a local plug type for their country. No additional software, drivers or configuration utilities are bundled with this power supply. The package contains only the adapter brick and the mains lead.

Questions about this item

How do I connect the 4.0 x 1.7 mm barrel plug without bending the centre pin?

Align the plug straight with the laptop socket, push gently until it seats fully, and avoid angling the connector — the centre pin is thin and bends easily if forced off-centre.

Which part of this 65 W 20 V 3.25 A adapter is most likely to need replacement first?

The DC cable near the barrel plug sees the most flexing; inspect it periodically and replace the whole unit if the insulation cracks or the connector becomes loose.

At what load does the 100-240 V 50/60 Hz input draw its maximum rated current during continuous use?

When the laptop draws the full 65 W output, the adapter pulls its highest input current; sustained operation at that level will warm the brick noticeably.
