90W replacement for Asus laptops
This 90W AC adapter replaces Asus 45W, 65W and 90W chargers for models including TN3402, Q524UQ, Q534UX, P2430UA and P2440UA. It uses a 4.5 mm plug tip with a centre pin and accepts 100-240V input for worldwide use. It does not replace 120W or 150W units.
Thermals, noise and power draw
The adapter delivers up to 19VDC at 4.74A with high power efficiency for consistent output. A ruggedised case is sealed against moisture and high humidity. Internal safety features filter input voltage spikes and limit output to protect the laptop. No fan is present, so operation is silent.
4.5 mm centre-pin connector
The DC plug measures 4.5 mm with an internal centre pin; verify this matches the laptop port before purchase. Two 6 ft cords are included: a UL-listed 2-prong AC cord and a DC cord. Buyers needing a 120W or 150W replacement cannot use this unit.

Questions about this item
How do I install the iTekiro 90W adapter and which step do people get wrong?
Plug the 6 ft 2-prong AC cord into a 100-240V outlet, then insert the 4.5 mm center-pin DC plug firmly into the laptop; the common mistake is not pushing the barrel connector all the way in so the center pin makes contact.
What maintenance or replacement will the iTekiro 90W adapter need later?
The UL-listed AC cord and 6 ft DC cord are the only wear items; inspect them periodically for fraying or damaged insulation and replace either cord if the jacket cracks or the connector loosens.
What limit appears first on the iTekiro 90W adapter under sustained load?
The adapter caps output at 19 V / 4.74 A (90 W max), so sustained loads above 90 W will hit the current limit before any thermal throttle engages.
