Lenovo 45W Chromebook Adapter

This 45W AC adapter supplies power to the Lenovo Chromebook N21 and recharges its battery. It is intended for users who need a spare or replacement charger for that specific model. The unit operates independently of the operating system. It provides a stable power connection wherever a wall outlet is available.

Compact Energy Efficient Design

The adapter weighs .60 lbs, making it light enough to carry in a laptop bag alongside the Chromebook. Its compact form factor allows it to sit unobtrusively on a desk or power strip. The unit plugs directly into a standard AC outlet without requiring a separate power brick or cable management. Energy efficient operation reduces unnecessary power draw when the battery is full.

Single Model Compatibility Limitation

This adapter is confirmed compatible only with the Lenovo Chromebook N21. Buyers who need to charge a different Lenovo model or a device from another brand cannot use this unit. There is no selector switch or interchangeable tip to broaden the range of supported hardware. Verify the exact model number before purchasing to avoid a mismatch.

Questions about this item

Does the 45W rating cap the power delivered to the Lenovo Chromebook N21?

Yes, the adapter supplies up to 45W to the compatible Lenovo Chromebook N21, so the system will not draw more than that rating.

What physical connector does the GX20K02934 use to fit the Chromebook N21?

It uses the standard Lenovo slim-tip barrel connector that mates with the N21 charging port.

What is the installation step users often miss with this adapter?

Plug the AC cord fully into the brick before connecting the barrel tip to the N21; a loose brick connection prevents charging.
