Compatible Asus Models

This 90W AC adapter replaces Asus 45W, 65W and 90W chargers for the Q529, P2440, P2520 and P2530 series laptops. It delivers 19VDC at up to 4.74A through a 4.5 mm tip with centre pin. The unit accepts 100 to 240V input at 50 to 60Hz for worldwide use.

Who This Suits

Buyers needing a direct replacement for a lost or damaged 90W Asus charger with the 4.5 mm centre-pin connector. The extra-long 6 ft AC cord plus 6 ft DC cord gives 12 ft total reach without an extension lead. It is not for owners of Asus models requiring 120W or 150W adapters.

Deciding Specification

The 4.5 mm plug tip with centre pin inside is the single detail that decides fit. Check your original charger tip against picture 3 before ordering; a different tip size or pin arrangement will not work.

Questions about this item

Does the 90 W brick run hot or make noise when it powers a laptop all day?

The adapter uses high-efficiency circuitry and a rugged sealed case to deliver continuous 19 V output up to 4.74 A without active cooling, so it stays quiet and only warm under full load.

What must I already have to use this charger with my Asus notebook?

You need a wall outlet that supplies 100–240 V at 50–60 Hz and a laptop whose charging port accepts the 4.5 mm centre-pin connector used on the Q529, P2440, P2520 and P2530 series.

Will this 90 W unit safely replace the original 65 W adapter that came with my older Asus model?

Yes, the output is rated 19 V at 3.42–4.74 A, covering 45 W, 65 W and 90 W Asus chargers, and internal surge protection guards the older hardware from voltage spikes.
