What this adapter replaces

This iTekiro 150W AC adapter fits MSI Pulse GL66, Stealth 15M, Sword 15, Sword 17, WF66 and WF76 laptops that use a 4.5 mm barrel tip with a centre pin. It replaces the original MSI 150W and 120W chargers but does not replace 180W, 230W or 240W units. Buyers who need a higher-wattage supply for a larger workstation model should look elsewhere.

Thermals and power behaviour

The adapter accepts 100 to 240 V AC at 50 to 60 Hz for worldwide use and delivers up to 150 W through selectable 20 V 7.5 A, 19.5 V 7.7 A or 19 V output rails. Built-in overload, short-circuit, over-voltage, over-current and over-temperature protections keep the brick running within safe limits during normal charging sessions.

What the bundled cord changes

A 6 ft UL-listed three-prong AC cord and a matching 6 ft DC cable are included, giving extra reach between the wall outlet and the laptop. The durable, sealed case resists water and humidity, so the charger survives travel and desk spills better than a bare-bones replacement.

Questions about this item

How do I install the 4.5 mm tip on my MSI laptop, and which step do people get wrong?

Align the centre pin inside the 4.5 mm plug with the laptop socket before pushing straight in; the common mistake is forcing the connector without the pin seated, which bends the pin and breaks the connection.

What maintenance will this 150 W adapter need later?

No internal maintenance is required; inspect the 6 ft AC cord and 6 ft DC cord for cracks or kinks, keep the vented case clear of dust, and replace the unit if the plug tip or cables show wear.

What limit appears first under sustained load on this adapter?

The 150 W maximum output is the first hard limit; continuous operation at 20 V 7.5 A or 19.5 V 7.7 A will trigger the built-in over-temperature protection before any other constraint.
