20V 45W AC adapter for IdeaPad and Yoga

This 20V 45W AC adapter replaces the original charger for many Lenovo IdeaPad and Yoga models. It accepts 100-240V input and delivers 20V at 2.25A through a 4.0 x 1.7mm connector. The unit is new and built to match the ADP-45DW and PA-1450-55L specifications. It suits owners of compatible laptops who need a direct replacement power supply.

7.5ft power cord included

The package supplies a 7.5ft charging cable alongside the adapter, so the set is ready to use without buying a separate mains lead. The cord length gives flexibility for desk or bedside charging positions. No software or extra accessories are bundled beyond the adapter and cord. This keeps the replacement simple and complete in one box.

45W output for listed models

The 45W rating covers the power needs of the IdeaPad 100, 110, 120, 130, 310, 320, 330, 510, 520, 530 and 710S series plus Yoga 710 11, 14 and 15 models listed in the compatibility data. It will not run laptops that require a higher wattage or a different connector size. Buyers with those machines should check their original charger rating before ordering.

Questions about this item

Will the 4.0 x 1.7mm connector or the 7.5ft cable need replacing first?

The connector is a fixed moulded tip rated for thousands of insertions; the 7.5ft cable flexes daily and its strain reliefs are the first point that typically wears.

What limits continuous output before the adapter shuts down?

The 45W ceiling at 20V 2.25A is the hard limit; sustained loads at or above that level trigger the built-in over-current protection.

How hot or noisy does the brick get when it runs all day?

With no fan inside, the unit is silent; the enclosure warms to a noticeable but safe temperature while delivering 45W continuously.
