Power Adapter Charger for Asus Vivobook S500C
The Asus Vivobook S500C large-format touchscreen ultrabook requires a highly stable direct current (DC) power feed to support its 15.6-inch display panel, computing components, and dual-drive storage systems. Selecting an aftermarket power supply with loose voltage tolerances or unshielded internal components can cause critical electrical ripples along the motherboard power lines. This often leads to an unresponsive capacitive touchscreen, erratic trackpad tracking, or premature cell breakdown within the laptop’s internal battery pack.
Asus Vivobook S500C Product Overview
This premium replacement AC adapter converts standard household electricity into a clean, regulated direct charge mapped exactly to original factory engineering limits. Unlike smaller ultrabooks of its generation that utilize a thin needle plug, the Asus Vivobook S500C relies on a larger, standard circular power port. This adapter features a reinforced outer plug collar, ensuring a flush, tight seat inside the laptop’s DC jack to eliminate physical port wiggle, dangerous micro-arcing, and unexpected charging dropouts.
Asus Vivobook S500C Key Features
-
Standard 5.5mm x 2.5mm Connector Tip: Features a robust, standard barrel profile designed specifically to align snugly with high-draw classic ultrabook ports.
-
65W Continuous Energy Delivery: Outputs a robust 19V 3.42A configuration that seamlessly satisfies higher performance hardware demands while rapidly charging the internal battery.
-
Smart Safety Control Module: Built-in micro-chips proactively guard the motherboard against volatile over-voltage (OVP), over-current (OCP), and short circuits (SCP).
-
High-Purity Copper Conductors: Equipped with heavy-gauge internal copper wiring to minimize resistance, reduce conversion heat loss, and extend cable life.

Asus Vivobook S500C Pros & Cons
Pros:
-
Widely Available Format: The 5.5mm x 2.5mm barrel is a highly standard Asus size, making it much easier to find replacements locally compared to proprietary pins.
-
Rapid Battery Replenishment: Full 65W output charges the larger ultrabook battery pack significantly faster than lower-tier 33W netsupply items.
-
Cool Operating Profile: Mapped precisely to the device’s energy-efficient architectural boundaries to avoid excessive heat buildup.
Cons:
-
Bulkier Form Factor: Requires a separate 3-pin cloverleaf power cord alongside the main power brick, increasing overall travel weight.
-
No Native Type-C Flexibility: Built around a dedicated round DC barrel input; it cannot be powered directly by modern universal USB-C Power Delivery wall chargers.
Asus Vivobook S500C Verdict
To protect your Asus Vivobook S500C laptop’s operational health, pairing it with a high-quality 19V 65W power adapter featuring a 5.5mm x 2.5mm barrel tip is the absolute baseline requirement. Verifying these physical dimensions ensures perfect mechanical fitment, keeps your touchscreen and system components running smoothly, and shields internal power routing lanes from early degradation.
