90W 19.5V Dell AC Adapter

This 90 watt AC adapter delivers 19.5 volts at 4.62 amps for a wide range of Dell Inspiron, Latitude, Precision and Studio laptops. It accepts a 100 to 240 volt input at 50 or 60 hertz for worldwide use and features a 7.4 by 5.0 millimetre barrel connector. The unit replaces numerous Dell part numbers including PA-10, PA-12 and PA-1900 series adapters. It is supplied new with a three-pin mains plug and the adapter itself.

Sustained 90W output with 65W fallback

Under continuous load the adapter maintains its full 90 watt rating at 19.5 volts and 4.62 amps without throttling. The design also supports 19.5 volts at 3.34 amps for 65 watt systems, so it runs cooler when powering less demanding models. Built-in protection circuits guard against over-voltage, over-current and short-circuit conditions during extended sessions. CE, FCC and RoHS certifications confirm compliance with international safety standards.

Check connector size and part number match

Verify that your laptop uses the 7.4 millimetre outer diameter and 5.0 millimetre inner diameter barrel tip before ordering. Confirm the original charger part number appears in the compatible list such as PA-10, PA-12, PA-1900-02D or 310-2862. Ensure the device requires 19.5 volts input; this adapter is not suitable for 20 volt USB-C or proprietary Dell power-delivery systems. Buyers needing a slimmer tip, higher wattage or USB-C output should look elsewhere.

Questions about this item

How much heat and fan noise does the 90W adapter produce when left running all day?

The brick has no internal fan and relies on passive cooling, so it runs silently; under continuous load the casing becomes warm but stays within normal operating limits for a 90W supply.

What must I already own to use this 7.4mm × 5.0mm connector on my Dell laptop?

You need a Dell laptop whose charging port accepts a 7.4mm outer by 5.0mm inner barrel — models listed include Inspiron 1525, Latitude E6420 and Precision M4500.

Will this 19.5V 4.62A unit safely charge an older Dell that originally shipped with a 65W PA-10 brick?

Yes — the adapter is rated 19.5V 3.34A 65W compatible, so it will power any Dell that uses the 7.4mm × 5.0mm tip and expects a 65W or 90W supply.
