Product Overview

ASUS 45W Adapter (19V, 2.37A) - Thin Pin

Comprehensive Connector Identification & Compatibility Guide

ASUS

A genuine or high-quality replacement 45W AC adapter for ASUS laptops, delivering 19V at 2.37A. It features a compact "thin pin" (4.0mm x 1.35mm) DC connector designed for ultrabooks like the ZenBook, Vivobook, and Transformer Book series.

The ASUS 45W Adapter (19V, 2.37A) is the standard power supply for a wide range of ASUS ultrabooks, Chromebooks, and compact laptops. Rated at 45 watts, it provides sufficient power for dual-core processors, SSDs, and integrated graphics without the bulk of larger 65W or 90W adapters.

Connector Identification: "Thin Pin"

The critical distinction for this model is the 4.0mm x 1.35mm connector. ASUS has used multiple connector types over the years—this "thin pin" is significantly smaller than the older "big pin" (5.5mm x 2.5mm).

ASUS Connector Comparison

Connector Type	Size	Description
Thin Pin (This Adapter)	4.0mm x 1.35mm	Narrow metal tip, used on modern ultrabooks
Big Pin	5.5mm x 2.5mm	Wider tip, used on older budget models

⚠️

Important: Verify your laptop's charging port before purchasing. The 4.0mm thin pin will NOT fit a 5.5mm port. Always verify the connector size before purchasing.
