Replacement 19 V 90 W Adapter

This 19 V 4.74 A power supply delivers up to 90 W through a 5.5 mm by 2.5 mm barrel connector. It accepts 100 V to 240 V AC input at 50 Hz to 60 Hz for worldwide use. The unit is built with over-voltage, over-load, over-current and short-circuit protection and carries CE, FCC and RoHS certifications.

For Asus Owners With Matching Tip

The charger suits owners of listed Asus models such as the X551, K53, K55, N56, U56 and Q501 series that require 19 V 4.74 A and the 5.5 mm by 2.5 mm plug. Buyers whose laptops need a different voltage, a higher wattage or a different connector diameter should look at other adapters.

5.5 mm by 2.5 mm Connector Decides Fit

The barrel tip measures 5.5 mm outer diameter and 2.5 mm inner diameter, so it only fits ports with that exact geometry. Verify the laptop's original adapter shows the same dimensions before ordering.

Questions about this item

How can I verify the adapter is delivering the correct 19V 4.74A output after connecting it to my ASUS laptop?

The laptop should power on and charge the battery normally; the adapter’s built-in over-voltage, over-load, over-current and short-circuit protection will engage automatically if the output drifts outside safe limits.

What comes in the box and is a separate AC mains cable required?

The package includes the 90W adapter unit with a fixed 5.5×2.5mm DC connector; a standard IEC C7 or C5 mains lead for 110–240V input must be supplied separately if not already owned.

Which connector size should I choose — 5.5×2.5mm or another variant — for my ASUS model listed in the compatibility list?

Select the 5.5×2.5mm tip; the product is built specifically for that barrel size and matches the 19V 4.74A 90W requirement of the listed ASUS laptops.
