90W 19.5V AC Adapter with USB Port

This 90 watt power supply delivers 19.5 volts at 4.62 amps through a 7.4mm barrel connector. It accepts 100 to 240 volt AC input at 50 to 60 hertz for worldwide use. A built-in USB port allows charging of a phone or tablet from the same outlet. Overload, over-voltage and short-circuit protection are included.

For Dell laptop owners needing a 7.4mm tip

The adapter matches the listed Dell Inspiron, Latitude, Precision, Vostro, Studio and XPS models that use the 7.4mm connector and require 90 watts at 19.5 volts. It is not suitable for laptops that need a different barrel size, a USB-C power input, or a higher wattage rating than 90 watts.

Connector size: 7.4mm barrel

The single specification that determines fit is the 7.4mm outer diameter with 5.0mm inner diameter barrel plug. Verify that your original charger uses this exact tip before ordering.

Questions about this item

Will the 7.4 mm tip or the USB port wear out first?

The 7.4 mm barrel connector is a mechanical part that can loosen after repeated insertion; the USB port is rated for many cycles but carries only low power.

What limits continuous output at 90 W?

Built-in overload, over-voltage and short-circuit protection will shut the unit down if the 90 W / 19.5 V / 4.62 A rating is exceeded.

How hot or loud does the adapter get when running all day?

No fan is present so it runs silently; the enclosure warms to a safe level under full 90 W load thanks to the protection circuitry.
