Lenovo 36200280 45W Laptop Power Supply Adapter

The Lenovo 36200280 45W Power Supply Adapter is a genuine Lenovo accessory designed to charge and power compatible Lenovo laptops and ultrabooks. Outputting 20V at 2.25A for a total of 45W, this adapter matches the power requirements of Lenovo's more energy-efficient portable machines, including many models in the IdeaPad and ThinkPad lines that ship with 45W chargers. As an OEM part, it meets Lenovo's specifications for voltage regulation, thermal safety, and connector fit, providing the same reliability as the adapter originally included with your device.

The adapter accepts input voltages from 100V to 240V at 50-60Hz, making it suitable for use anywhere in the world with just a plug adapter—no bulky voltage converter needed. This makes it a practical choice as a travel spare or desk-side backup charger. Its compact size reflects the lower power demands of the laptops it supports, keeping it lighter and more portable than 65W or 90W alternatives. Buyers should verify that their Lenovo laptop is compatible with part number 36200280 before purchasing, as using an adapter with the wrong wattage or connector can result in slow charging or incompatibility.
