Universal 90W 19V Laptop Power Adapter

This universal AC adapter delivers 90 watts at 19 volts and 4.74 amps for compatible laptops. It accepts a 100 to 240 volt input at 50 to 60 hertz for worldwide use. The unit includes multiple interchangeable tips to fit various barrel connectors. It is finished in black and measures approximately 12.5 by 4.8 centimetres.

Suitable For Listed Brands Only

The adapter suits owners of HP, ASUS, Acer, IBM, Dell, Sony or Toshiba laptops that require a 19V 4.74A supply with a matching tip. Buyers whose laptops need a different voltage, a higher wattage or a proprietary connector not in the supplied set should look elsewhere. The included tips cover many common barrel sizes but not every manufacturer-specific plug.

Critical Spec 5.5mm x 2.5mm Connector

The primary connector measures 5.5 millimetres outer diameter by 2.5 millimetres inner diameter. Additional tips provide sizes such as 7.4mm x 5.0mm, 4.5mm x 3.0mm, 6.5mm x 3.0mm, 6.0mm x 3.0mm and several smaller Asus-specific dimensions. Matching this exact tip size to the laptop's DC jack is the single specification that determines compatibility.

Questions about this item

Will the 5.5 mm x 2.5 mm connector fit my laptop's charging port?

The adapter includes a 5.5 mm x 2.5 mm tip among 17 interchangeable connectors covering HP, Dell, Asus, Acer, Sony, Toshiba and IBM models.

How do I attach the correct tip without damaging the pin?

Align the chosen connector with the DC cable end, push straight in until it clicks; forcing it at an angle bends the centre pin.

When should I replace the AC cable or the adapter itself?

Replace the figure-8 AC lead if the insulation cracks; replace the 90 W brick if output drops below 19 V 4.74 A or the housing overheats.
