The wall-adapter versions have compatible 20V, 3.25A, 65W output and a 4.0mm × 1.7mm computer-side plug, but they do not necessarily have the detachable IEC C5 power-cable arrangement. This does not affect or change the functionality, they are interchangeable and functionally equivalent. 

⚠️ Critical Connector Compatibility Notice

Several physically incompatible 65W adapters share similar descriptions and partial model numbers. Confirm all of the following before ordering:

• The original system uses a 4.0mm × 1.7mm round barrel connector.
• The connector is hollow and does not have a center identification pin.
• The cable exits the molded connector at a 90-degree angle.
• The system requires 20V DC.
• The system requires no more than 3.25A or 65W.
• The barrel length, connector housing, and insertion depth match the original.
• If reusing the original wall cable, the adapter must have an IEC C6 inlet for an IEC C5 cloverleaf cable.

⭐ 65W Replacement for Same-Tip 45W Adapters

A 65W, 20V adapter can safely replace a 45W, 20V adapter when both use the exact 4.0mm × 1.7mm center-positive connector. The laptop draws only the current it requires.

Examples of current 45W same-tip label families include:

GX21J75540 / 5A11H02888 / ADLX45NDC3A
GX21J75541 / 5A11H02879 / ADLX45DLC3A
GX21J75542 / 5A11H02880 / ADLX45NCC3A

These are one-way upgrade references, not exact 65W equivalents. A 45W adapter should not be substituted for a system originally requiring 65W.

✅ Confirmed Compatibility

Compatibility applies to configurations equipped with the 20V 4.0mm × 1.7mm round charging port and requiring 65W or less. Some model families were also produced with USB-C, rectangular slim-tip, or higher-wattage charging systems.

⚙️ Fit Notes

• The connector must measure 4.0mm outside diameter and 1.7mm inside diameter.
• This connector is hollow and does not contain a center identification pin.
• Do not confuse this connector with the visually larger 5.5mm × 2.5mm round plug.
• Do not confuse it with the rectangular yellow slim-tip connector.
• This adapter does not connect to a USB-C charging port.
• A 65W adapter can replace a matching 45W adapter, but a 45W adapter should not replace a system requiring 65W.
• Do not use this adapter for a system requiring more than 65W.
