90W 19V AC adapter for Asus 15.6-inch laptops

This 90-watt AC adapter delivers 19 volts at 4.74 amps through a 4.5 by 3.0 millimetre barrel connector. It replaces Asus part numbers such as PA-1650-48, PA-1900-29, PA-1900-30 and ADP-90YD B. The unit suits owners of compatible Asus Q524, Q534, F560 and P-series 15.6-inch touch-screen laptops who need a direct replacement charger.

Sustained output with full protection suite

The adapter accepts a universal 100 to 240 volt input at 50 to 60 hertz and maintains a steady 90-watt output during continuous use. Built-in safeguards include over-current protection, over-voltage protection, short-circuit protection and total power protection. Every unit undergoes 100 per cent testing before delivery and meets UL, CE, FCC and RoHS standards.

4.5 by 3.0 millimetre barrel connector decides fit

The sole specification that determines compatibility is the 4.5 millimetre outer diameter and 3.0 millimetre inner diameter of the output plug. If your laptop requires a different barrel size or a USB-C power input, this adapter will not connect. Buyers who need a different connector profile or a higher wattage unit should verify their original charger specifications before ordering.

Questions about this item

How much heat or noise does the 90W adapter produce when it runs all day?

The 19V 4.74A unit includes over-current, over-voltage and short-circuit protection, so it stays within safe thermal limits during continuous operation.

What must I already own for the 4.5×3.0 mm connector to work?

You need an ASUS laptop from the listed Q524, Q534, F560, P2440, P2520, P2530 or P2540 series that uses a 19V 4.74A barrel jack.

Will this 90W charger run an older ASUS model that originally shipped with a 65W brick?

Yes — the adapter supplies 19V at up to 4.74A and carries UL, CE, FCC and RoHS certification, so it safely powers any compatible ASUS notebook that accepts 19V input.
