Power Adapter Charger for Asus X556UQ-NB51

Power Adapter Charger for Asus X556UQ-NB51

The Asus X556UQ-NB51 requires the modern “small pin” charging standard. Unlike many earlier Asus X555 models that used the larger 5.5mm connector, your specific X556 series laptop requires a compact 4.0mm x 1.35mm barrel tip. Using a charger with the wrong pin size will cause a physical mismatch and can potentially damage the internal charging port of your laptop.

Asus X556UQ-NB51 Product Overview

This replacement AC adapter is engineered to provide the exact voltage and amperage required for the X556UQ-NB51 series. Because this model is thinner than older X555 series laptops, it requires this specific “small pin” connector to fit correctly. A high-quality replacement ensures stable, ripple-free power delivery, which is essential for preventing system stuttering, screen flickering, or unexpected shutdowns during intensive computing tasks.

Asus X556UQ-NB51 Pros & Cons

Pros:

• Perfect Mechanical Fit: Using the correct 4.0mm x 1.35mm tip prevents the mechanical stress and port damage associated with using unauthorized adapter types.

• Unthrottled Performance: 65W output provides the necessary headroom for the X556UQ-NB51 hardware to perform as designed.

• Safety & Stability: Quality units include surge protection, which is essential for consistent performance on local power grids.

Cons:

• Fragile Tip Profile: The 4.0mm x 1.35mm pin is physically smaller and more sensitive to bending than the old 5.5mm standard; ensure the plug is inserted straight.

• Model Specificity: Not compatible with chargers from older, bulkier Asus models.

Asus X556UQ-NB51 Verdict

Your Asus X556UQ-NB51 must be paired with a 19V 65W charger featuring the 4.0mm x 1.35mm “small pin.” Avoid any “universal” chargers that do not clearly specify this small-diameter tip, as they will not connect properly to your laptop’s charging jack.
