Compatible Lenovo IdeaPad Models

This 45W AC adapter fits Lenovo IdeaPad S340 and S145 laptops including the 14IWL, 15IWL, 14IIL, 15IIL, 14IGM, 15IGM and 14IIL variants. It is intended for owners of those specific models who need a replacement or spare power supply.

Input Voltage and Frequency Range

The adapter accepts 100-240V at 50-60Hz, making it suitable for mains power in most countries without a separate voltage converter. Output is fixed at 20V 2.25A, so it cannot charge devices that require a different voltage or current profile.

45W Output Decides Suitability

The single specification that determines whether this is the correct part is the 45W output rating. Laptops that demand a higher wattage charger will not operate correctly with this adapter, while models specified for 45W will charge as designed.
