Compatible Lenovo IdeaPad 3 Models

This 45W car charger replaces the standard AC adapter for several Lenovo IdeaPad 3 variants, including the 81W40016CF, 81W40019US, 81W40020CC, and 15IIL05 81WE series. It connects to a 12V or 24V cigarette lighter socket in a car, boat or RV, letting you power the laptop and charge its battery while the vehicle is running. The right-angle DC plug reduces strain on the laptop's power jack.

Output Capacity and Vehicle Voltage Range

The adapter delivers 20V at 2.25A for a 45W output, matching the original Lenovo supply. It accepts a wide 12V to 24V DC input, so it works in both standard cars and larger vehicles with 24V systems. The unit can supply up to 65W maximum, providing headroom for brief peaks, but sustained loads above 45W are not supported. It will not operate from a mains AC outlet.

Thermals, Noise and Power Draw

The charger includes short-circuit and over-temperature protection that shuts it down if internal heat rises excessively. A smart LED indicator shows power status without adding audible noise, as the unit has no moving parts. Its compact 4.33 by 1.69 by 1.18 inch enclosure weighs 9.7 oz and draws only the power needed by the connected laptop, minimising drain on the vehicle battery.

Questions about this item

Will this 45 W charger work with my older Lenovo IdeaPad 3 that uses a 65 W brick?

Yes — the adapter outputs 20 V at 2.25 A for 45 W and is listed as a replacement for genuine Lenovo 20 V 45 W and 65 W units, so it will power compatible IdeaPad 3 models.

How do I know the charger is functioning once I plug it into the 12 V socket?

A smart LED indicator lights up when the adapter receives 12–24 V DC input and is delivering power to the laptop.

What comes in the box and do I need any extra cables?

The package includes the auto adapter with its attached right-angle DC cable; no additional cables are required for the 12 V / 24 V cigarette-lighter outlet.
