Power Delivery

This 240 W AC adapter supplies 20 V at 12 A through a 6.0 × 3.7 mm barrel connector. It accepts 100–240 V input at 50–60 Hz for worldwide mains compatibility. The unit is built for Asus Zephyrus, ROG Flow, TUF Gaming, Strix Scar, Vivobook Pro and ProArt Studiobook models that specify this exact connector and wattage.

Bundle Contents

The package includes the adapter and a detachable power cord so you can replace a lost or damaged original without buying extra cables. No additional software, drivers or proprietary docks are supplied; the adapter works immediately on any supported laptop that recognises the 240 W profile. Users needing a higher wattage brick must look elsewhere.

Connector Constraint

The 6.0 × 3.7 mm barrel is the sole mechanical and electrical interface; laptops with USB-C Power Delivery, larger barrels or proprietary tips cannot use this adapter. The 240 W ceiling also means systems that draw more power under load will not charge or may throttle. Buyers who need more than 240 W or a different connector type cannot use this product.

Questions about this item

How often will the 6.0×3.7 mm barrel connector need replacement under daily plug cycles?

The connector is a standard 6.0×3.7 mm barrel rated for thousands of insertions; replace only if the centre pin loosens or the sleeve cracks.

What component hits its limit first when the adapter runs at 240 W continuously?

The internal thermal protection trips first if the 20 V 12 A output is sustained in a confined space with restricted airflow.

How much fan noise and heat does the 240 W unit produce during all-day use?

The adapter is passively cooled with no fan; expect warm surface temperatures but silent operation at full 240 W load.
