19V AC Adapter for Asus Ultrabooks

This 19V AC adapter replaces the original power supply for Asus X750, S400, K45, S301, S550 and S551 series laptops. It delivers 19V output with worldwide 100-240VAC 50/60Hz input for international use. The package includes the power cord cable for immediate connection. It suits owners of these specific Asus models needing a direct replacement charger.

Sustained operation with protection circuits

The adapter maintains steady 19V output during continuous charging and laptop operation. Built-in over voltage, short circuit and over current protections activate automatically if irregular conditions occur. These safeguards prevent damage to both the adapter and the connected laptop during extended sessions. The unit is tested before shipment to verify reliable performance under load.

New replacement with broad model coverage

Supplied new, the adapter fits multiple Asus ultrabook and notebook variants including X750jb, X750jb-db71, X75a-dh32, X75a-ds51, S400ca-db51t, K45Vj, S301La, S301Lp, S550Cb, S550Cm and S551La. The barrel connector matches the original charging port on these devices. Buyers with Asus models outside this listed compatibility range should verify connector size and voltage before purchasing.

Questions about this item

How much heat or noise does the 19V adapter produce when left plugged in all day?

The unit has no fan and runs silently; its over-voltage, short-circuit and over-current protections keep temperatures low during continuous use.

What must I already own for this charger to power my laptop?

You need a compatible Asus model such as the X750, S400, K45, S301, S550 or S551 series and a working mains socket for the included power cord.

Will this 19V supply work reliably with an older Asus ultrabook I still use?

Yes, the wide 100-240VAC 50/60Hz input and 19V output match the original specifications for the listed legacy Asus ultrabooks and notebooks.
