iTekiro 150W AC Adapter for Asus UX550 UX580

This 150W AC adapter from iTekiro replaces original 120W and 90W chargers for Asus UX550 and UX580 series laptops. It delivers up to 20V at 7.5A through a 4.5 mm barrel connector with a centre pin. The unit accepts worldwide input from 100 to 240V at 50 to 60Hz. It does not replace 180W or 230W adapters.

Thermals noise and power draw in normal use

The adapter includes overload, short-circuit, over-voltage, over-current and over-temperature protection circuits. Its case is designed to resist extreme conditions while sealing out water and humidity. High power efficiency provides a steady and reliable power source for the laptop during standard operation. A six-foot UL-listed AC cord and six-foot DC cord give flexible placement.

Behaviour under sustained load rather than short

Smart safety features continuously monitor output to maintain stable voltage and current during extended charging sessions. The durable enclosure helps dissipate heat so the adapter can sustain its 150W maximum rating without throttling. Protection circuits engage automatically if limits are exceeded, preventing damage to the laptop or the adapter itself. It is not suitable for systems that require 180W or 230W input.

Questions about this item

How do I install the iTekiro 150W AC adapter on my Asus UX550 or UX580, and what step is often missed?

Connect the 4.5 mm plug with its centre pin firmly into the laptop's DC jack, then attach the 6 ft AC cord to the adapter brick and plug it into a 100-240V outlet; the step people miss is seating the centre pin completely so the laptop recognises the 150W capability.

What maintenance or replacement will this iTekiro adapter need over time?

The 6 ft UL-listed AC cord and 6 ft DC cable can wear at the strain reliefs; inspect them periodically and replace the whole adapter if insulation cracks or the centre pin becomes loose, since no user-serviceable parts exist inside the sealed case.

What limit appears first when this adapter runs at full load for long periods?

The 150W maximum output (20V 7.5A or 19.5V 7.7A) is the hard ceiling; sustained loads above that will trigger the built-in overload protection and shut the unit down until it cools.
