Compatible 65W higher-output replacements:

ADLX65CLGC2A, 5A10K78736

These two references provide 20V 3.25A and 65W through the same round connector. They can replace the 45W adapter when the system requires 20V and the identical 4.0 × 1.7mm connector, but they are not native 45W models.

⭐ Bulk / Volume Orders

Need a bulk or project quantity? We regularly supply schools, businesses, repair facilities, resellers, refurbishers, and IT deployments.

Simply enter the required quantity and place the order directly through the website. Available bulk quantities can be purchased through the normal online checkout, and we will get the order processed, carefully prepared, and moved through fulfillment promptly.

⚠️ Important Note

Always compare the complete specification with the original adapter: 20V DC, 2.25A, 45W, and a round 4.0mm outer × 1.7mm inner barrel connector without a center pin.

This is not the rectangular Slim Tip or USB-C version. A connector that looks similar can still have a different size or electrical configuration. Using the wrong voltage, connector, or adapter type can cause charging problems or equipment damage.

⚙️ Fit Notes

• Confirm the original adapter says 20V 2.25A 45W and uses the 4.0mm outer × 1.7mm inner round connector.
• This adapter does not fit rectangular Slim Tip or USB-C charging ports.
• Do not cross-reference ADLX45NAC3A with this round-tip adapter; that model uses the incompatible rectangular connector.
• Some product families were sold with 45W, 65W, or higher-wattage adapters depending on the processor, graphics, and regional configuration.
• If the original adapter is rated 65W, use a compatible 65W replacement unless the system’s service documentation specifically permits 45W.
• A 65W adapter with the same 20V output and identical 4.0 × 1.7mm connector can normally replace a 45W adapter because the computer draws only the current it requires.
• Housing style, supplier, cable length, AC wall connection, and printed model suffix may vary across genuine revisions.
• A matching wattage alone does not establish compatibility; voltage, connector dimensions, connector style, and polarity must also match.

✅ Confirmed Compatibility

The following list consolidates verified 45W round-tip system families and configurations. Some model families were manufactured with both 45W and 65W adapters. For models marked “selected configurations,” confirm that the original adapter is rated 20V 2.25A 45W and uses the 4.0 × 1.7mm round connector.
