COREPARTS 230W 20V 11.5A AC Power Adapter with USB Square Connector for Lenovo Laptops (02DL144-CP)

When your Lenovo laptop refuses to charge and the battery drains faster than you can find an outlet, the problem is often a failing or incompatible power adapter.

This replacement adapter is built to keep high-performance laptops running through demanding workloads, from video editing to 3D rendering, without throttling or unexpected shutdowns.

Tips

Before ordering, confirm that your laptop's original adapter is rated at 230W, 20V, and 11.5A, and that the DC plug is the slim rectangular type. Using a lower-wattage adapter may cause the laptop to charge slowly or not at all under heavy load. For best results, connect the adapter directly to a wall outlet rather than a power strip, and keep the ventilation area around the adapter clear to prevent overheating.
