Replacement 45 W AC adapter for Lenovo IdeaPad

This 45 W adapter replaces the original charger for a wide range of Lenovo IdeaPad and Yoga models. It delivers 20 V at 2.25 A through a 4.0 mm × 1.7 mm barrel connector. The unit accepts 100–240 V input for worldwide use and includes a detachable three-prong power cord. It is supplied new with CE, FCC and ROHS safety certification.

Upgrading from a lost or damaged 45 W

The adapter is a direct substitute when the factory supply is missing, frayed or no longer holds a charge. It matches the 45 W rating used by many 11-inch to 17-inch IdeaPad and Yoga systems, so the swap restores full charging speed without over- or under-powering the laptop. The jump is worth it whenever the original brick is unavailable or the cable has failed at the strain relief.

Fits into a travel or desk setup with a standard

The brick uses a common three-prong inlet, so any IEC C13 mains lead can replace the bundled cord for a shorter or longer reach. Its 100–240 V input removes the need for a voltage converter when moving between regions. The 4.0 mm × 1.7 mm tip mates only with compatible Lenovo ports; it will not fit laptops that require USB-C Power Delivery, a larger barrel or a rectangular connector.

Questions about this item

What connector size does this adapter use to fit the Lenovo laptop charging port?

The adapter uses a 4.0 mm × 1.7 mm barrel connector that matches the DC-in port on the listed IdeaPad, Yoga and Flex models.

How do I connect the adapter, and what step is often missed?

Plug the three-prong IEC power cord into the adapter brick, then insert the 4.0 mm × 1.7 mm tip firmly into the laptop until it seats; the step often missed is pushing the tip in until it clicks.

When will the power cord or adapter need replacement?

Replace the IEC power cord if the plug or insulation shows damage, and replace the adapter if the output drops below 20 V 2.25 A or the connector becomes loose.
