What this adapter replaces

This 150 W AC adapter delivers 20 V at 7.5 A through a 4.5 mm tip with a centre pin. It is built for the MSI Pulse GL66 and Stealth 15M models listed in the compatibility data, including the 11UCK, 11UDK, A11SDK and A11SEK series. Buyers who need an 180 W, 230 W or 240 W unit should look elsewhere because this adapter does not replace those higher-wattage chargers.

Cords and protections included

A 6 ft UL-listed 3-prong AC cord and a 6 ft DC cord are supplied in the box, giving extra reach between the wall outlet and the laptop. The brick incorporates overload, short-circuit, over-voltage, over-current and over-temperature protection, and its sealed case resists water and humidity. No software or additional accessories are bundled.

Installation notes

Connection is straightforward: plug the AC cord into the adapter, the DC tip into the laptop, and the 3-prong plug into a 100–240 V 50/60 Hz mains socket. The only common issue is accidentally ordering this 150 W model for a laptop that requires the 180 W, 230 W or 240 W version, which this unit cannot support. Verify the original charger wattage before purchasing.

Questions about this item

Will the 4.5 mm centre-pin tip wear out and need replacing?

The tip is a fixed part of the 6 ft DC cord; if it becomes loose or damaged the whole adapter must be swapped.

What stops the 150 W output first when the laptop runs flat-out?

The adapter is rated for 150 W maximum; sustained loads above that will trigger its overload protection and shut the unit down.

How hot or loud does the brick get after hours of charging?

The sealed case has no fan, so it runs silently; warmth is normal but the housing is designed to dissipate heat without overheating.
