Reliable 65W Replacement Charger for Lenovo Laptops

This 65W AC adapter delivers 20V 3.25A output through a 4.0x1.7mm round tip connector. It serves as a direct replacement for lost or damaged original chargers across many IdeaPad, Yoga, and Flex models. The unit includes the AC adapter and a detachable AC power cord for immediate use.

65W Output with 45W Backward Compatibility

The adapter provides up to 65W maximum power while safely supporting Lenovo systems rated for 45W that share the same 20V round-tip input. Built-in protections guard against short-circuit, over-current, and over-voltage events during charging. It cannot power laptops requiring higher wattage or different connector types.

Replaces Common Lenovo Part Numbers

This unit matches OEM part numbers such as ADLX65CCGC2A, ADLX65CDGU2A, GX20L29355, and 5A10H42919 among others. Buyers must verify their laptop model, required 20V output, and exact 4.0x1.7mm tip size before purchase. It is not suitable for devices using USB-C charging, slim-tip connectors, or proprietary square-tip designs.

Questions about this item

Will the 65W adapter with 4.0x1.7mm tip run an older IdeaPad 330 that originally shipped with a 45W charger?

Yes — the adapter delivers 20V 3.25A (65W max) and is backwards compatible with 45W systems using the same 20V round tip; verify your laptop requires 20V before connecting.

How can I confirm the charger is working correctly after I plug it in?

The laptop battery icon should show charging, the adapter LED (if present) stays solid, and the brick remains only warm — not hot — during normal 65W load.

Does the package include both the AC adapter brick and the detachable mains cord?

Yes — the box contains one 65W AC adapter with 4.0x1.7mm round tip and one standard AC power cord; no extra cables are needed.
