45W USB Square Yellow Tip Adapter

This 45W AC adapter delivers 20V at 2.25A through a USB square yellow tip. It replaces Lenovo part numbers such as ADLX45NCC3A, ADLX45NDC3A and ADLX45NLC3A. The unit suits owners of compatible Lenovo Flex, G40, G50, S21, S210, Yoga 2 11, Yoga 2 11S and ThinkPad Helix models who need a direct replacement charger.

Installation and common issues

The package includes the adapter and an AC power cable for immediate use. Input voltage covers 100-240V at 50-60Hz for worldwide mains compatibility. The yellow square tip must match the device port exactly; a similar-looking round or differently coloured tip will not fit. Forcing an incorrect connector damages the laptop charging socket and voids any return.

Check before ordering

Confirm the laptop requires 20V 2.25A 45W output and uses a yellow square USB-style connector. Verify the original charger part number against the listed compatibles such as ADLX45NCC3A, ADLX45NDC3A, ADLX45NLC3A, 45N0290, 45N0294, 45N0298 or PA-1650-72. Devices needing a different voltage, amperage or connector shape are not supported by this adapter.
