45W AC Adapter for Asus Ultrabooks

This 45-watt adapter replaces the original charger for a wide range of Asus ultraportable models including the UX330, UX360, Q302 and Q504 series. It accepts a universal AC input from 100 to 240 volts and delivers a regulated 19-volt output at up to 2.37 amps. Travellers and remote workers can use it as a direct spare or a second charger kept at a desk.

Broad model coverage reduces spare-part confusion

The single unit covers dozens of Asus part numbers such as the X201E, X202E, X541NA, X542UA, C202SA, C300SA and E402WA. Buyers no longer need to match exact sub-model suffixes; the adapter fits the listed families without extra tips or cables. This simplifies inventory for IT teams managing mixed fleets.

Suits owners of listed Asus notebooks needing

It is not for laptops that require a higher wattage brick, a different output voltage, or a USB-C power delivery connector. Buyers with gaming-class Asus models or newer ultrabooks that charge solely via USB-C should look elsewhere. Verify the tip size and wattage against the original unit before purchase.

Questions about this item

Will the detachable cord on this 45W adapter need replacing before the brick itself?

The supply cord is a standard IEC C7 figure-8 lead; if the plug or cable sheath wears you can swap the cord alone without replacing the whole 19V 2.37A brick.

What stops the charger from delivering more than 45W during long sessions?

The unit is rated for a maximum 45W output at 19V 2.37A; the internal current-limit circuit caps power there, so sustained loads above that will cause voltage droop or shutdown.

How hot does the 19V 1.75A brick get when left plugged in all day?

At full 45W load the case reaches typical external power-supply temperatures; the 100-240V input design spreads heat across the sealed enclosure without a fan.
