240W AC adapter for MSI Pulse and Stealth laptops

This iTekiro 240W replacement charger powers compatible MSI Pulse and Stealth series notebooks. It delivers up to 20V at 12A or 19.5V at 12.3A through a 4.5 mm barrel tip with a centre pin. The unit includes a six-foot AC cord and a six-foot DC cord for flexible placement. It is a new adapter built to replace several original MSI power supplies.

Capacity and headroom for 240W MSI systems

The adapter supplies a maximum of 240W, matching the original MSI 240W, 230W, 200W and 180W chargers listed for the Pulse GL66, GL76 and Stealth 14 Studio models. It will run those laptops and charge their batteries whether the system is on or off. It does not replace MSI 280W, 300W or 330W adapters, so buyers needing higher wattage must look elsewhere.

4.5 mm centre-pin tip decides compatibility

The single specification that determines fit is the 4.5 mm diameter plug tip with a centre pin inside. Only laptops using that exact connector will work with this adapter. The worldwide 100–240V input and UL-listed AC cord support international use, but the tip geometry remains the deciding factor for every purchase.

Questions about this item

Will this 240 W adapter run my older 180 W MSI laptop without issues?

Yes, it replaces MSI 180 W, 200 W, 230 W and 240 W chargers, so it will power your older unit safely.

How can I confirm the adapter is delivering 20 V 12 A or 19.5 V 12.3 A after I plug it in?

The brick’s label lists both output profiles; a multimeter on the 4.5 mm tip will show the active voltage under load.

Does the package include the 6 ft AC cord and 6 ft DC cord, or must I buy them separately?

Both cords are supplied — UL-listed 3-prong AC cable and DC cable — nothing extra is required.
