Product Description

The Asus Small Pin Q46 40W 19V 2.1A Original Laptop Adapter is a genuine slim‑tip charger designed for select Asus notebooks, ultrabooks and netbooks that use the 2.5 × 0.7mm small pin connector and a 40W 19V power rating. If your original Asus charger is lost, damaged, or you want a second adapter for the office or travel, this OEM‑grade adapter is the safest and most reliable way to keep your Asus laptop powered.

Rated at 40W (19V, 2.1A), this adapter provides exactly the power your compatible Asus device is designed for. Using a charger with the correct voltage, current, and connector type is critical to protecting your laptop’s motherboard and battery. Under‑powered or non‑matching chargers can cause:

• Slow or intermittent charging
• Performance throttling under load
• Overheating or long‑term component stress

The Asus Small Pin Q46 40W 19V 2.1A Original Laptop Adapter matches Asus’ official specification, helping ensure stable charging, safe operation, and long‑term device health.

The adapter uses a small barrel connector (AC 2.5 × 0.7mm), often called the “Asus small pin.” This slim round tip is common on compact Asus models such as older Eee PCs, some VivoBook and mini‑notebooks, and low‑power 11–14″ laptops. Its compact size makes it perfect for lightweight and travel‑friendly laptops, and the adapter itself is similarly compact, making it easy to carry in a bag or backpack without taking up much space.

As an original or OEM‑grade charger (check product listing), this adapter features high‑efficiency circuitry, strong insulation, and multiple safety protections (over‑voltage, over‑current, short‑circuit, and over‑temperature). The durable cable and robust strain reliefs are built to withstand everyday plugging and unplugging, which is crucial for students, commuters, and mobile professionals.
