iTekiro 90W AC Adapter 4.5mm tip for Asus UX450FDA UX481FL UX533FD

SKU CH-7GMS-K38G5

Replacement 90 W AC adapter with 4.5 mm tip powers compatible Asus laptops and includes extra-long 6 ft cords

  • Replaces Asus 45W, 65W and 90W chargers with 90W max output
  • 12 ft total cable reach from 6 ft AC plus 6 ft DC cords
  • 5 mm tip with centre pin fits listed UX and P series models
  • UL listed AC cord and internal surge protection guard against voltage spikes
  • Worldwide 100‑240V input lets you charge anywhere without a voltage converter

Replacement 90W AC adapter for Asus ultrabooks

This iTekiro adapter supplies 19 V at up to 4.74 A and replaces 45 W, 65 W or 90 W Asus chargers. It fits the UX450FDA, UX481FL, UX533FD and several related models that use a 4.5 mm tip with a centre pin. The unit accepts 100–240 V input for worldwide use.

Steps up from lower-wattage bricks

It replaces 45 W and 65 W adapters when the laptop demands more power, but it does not replace 120 W or 150 W units. The jump is worth it if the original charger was rated below 90 W and the connector matches the 4.5 mm centre-pin specification.

Straightforward swap with long cords

A 6 ft AC cord and a 6 ft DC cord give ample reach without extension leads. The ruggedised case resists moisture and humidity. The only common issue is ordering the wrong tip size, so verify the 4.5 mm centre-pin plug before purchasing.

Questions about this item

What plug size does this adapter use and will it fit my Asus laptop?

The adapter uses a 4.5 mm plug tip with a centre pin inside, matching the port on the listed Asus UX450FDA, UX481FL and UX533FD models.

How do I connect the two cables and which end goes where?

Plug the 6 ft 2-prong AC cord into the wall outlet and the brick, then connect the 6 ft DC cord from the brick to the laptop; the brick must sit between the two cords.

When should I replace the AC power cord or the DC cable?

Replace either cable if the insulation is cracked, the plug pins are bent, or the connector feels loose in the laptop port.
