Compatible Samsung Galaxy Book Flex Alpha 13.3

This 40W AC adapter is built for the Samsung Galaxy Book Flex Alpha 13.3 NP730QCJ, NP730QCJ-K02US and NP730QCJ-K01US laptops. It delivers 19V at 2.1A to match the original charger specification. The package includes one adapter and one power cord. Buyers with other Samsung models or different voltage requirements should look elsewhere.

Worldwide 100-240V input with 50-60Hz frequency

The adapter accepts 100-240V AC at 50-60Hz, so it works on mains supplies around the world without a separate voltage selector. A single fixed 19V 2.1A output means there is no manual switching or auto-sensing beyond the stated range. Users needing adjustable voltage or a different plug standard cannot use this unit.

Fixed 40W 19V 2.1A output decides fit

The single deciding specification is the 19V 2.1A 40W output; the laptop must require exactly these values. If the device needs higher wattage, lower voltage or a different connector polarity, this adapter will not work. No other rating or feature overrides this requirement.

Questions about this item

Is there more than one power-rating option for this Samsung Galaxy Book Flex Alpha 13.3 adapter?

The listing supplies a single 19V 2.1A 40W unit with one power cord, so no alternative capacities are offered.

What does the 40W output actually deliver to the NP730QCJ in daily use?

It provides the exact 19V 2.1A the laptop expects, powering the system and charging the battery simultaneously.

Which connector standard does the 19V 2.1A tip use and what does that limit?

The barrel tip matches the NP730QCJ charging port, limiting use to that Samsung model family.
