Lenovo 45W AC Wall Laptop Power Adapter

The Lenovo GX20K11838 is a 45 W AC wall adapter built for anyone who needs a simple, dependable way to keep a compatible Lenovo laptop charged. It connects to a standard outlet and delivers a steady 45 W to IdeaPad and Flex models, so you can write reports, stream lectures, or edit photos without watching the battery level slip away.

Lenovo designed this adapter with daily movement in mind. It weighs about 160 g, roughly the weight of a smartphone, and slips easily into a backpack pocket or desk drawer. The input range of 100 to 240 V at 50 to 60 Hz means you can fly from London to Los Angeles, plug in with a travel converter, and keep working without interruption.

Safety and efficiency are built into the circuitry. The adapter carries Lenovo safety approvals and uses an energy conscious design that reduces wasted power while your laptop tops off. Each box includes the AC cable and a quick installation guide, so you are ready to charge right away. A one year warranty adds an extra layer of confidence.

Keep a spare at the office, leave another in your travel bag, or replace a lost original. The GX20K11838 ensures you never need to ration battery life during a meeting, a lecture, or a long flight.
