90W Universal AC Adapter with 15 Tips

The DELL UB-90HB is a 90W universal AC adapter supplied with 15 interchangeable barrel tips. It accepts AC 100V-240V input and delivers selectable DC outputs including 20V 4.5A, 19.5V 3.34A and 19V 3.42A. Automatic voltage detection matches the connected device without manual switching. The unit is new and intended as a replacement or spare charger for compatible laptops and 19V peripherals.

Suits owners of multiple 19V barrel-powered devices

This adapter suits users who need one charger for several notebooks, monitors, speakers or routers that use the included tip sizes. It is not for devices that charge exclusively through USB-C Power Delivery. Buyers who require a higher wattage rating than 90W or a tip size not in the 15-piece set should look at other options.

Stable 90W output under continuous load

The adapter maintains a consistent 90W output during extended charging sessions while the laptop is in use. Reinforced cable construction and robust housing resist heat build-up and physical wear from daily connection cycles. Automatic voltage regulation prevents power fluctuations across the supported 15V to 20V range, protecting connected equipment during sustained operation.

Questions about this item

What must my laptop have so the DELL UB-90HB adapter can power it?

Your laptop needs a barrel-type DC input that matches one of the 15 included tips and accepts 15 V, 16 V, 18.5 V, 19 V, 19.5 V or 20 V up to 90 W. The adapter auto-detects the correct voltage.

Will the DELL UB-90HB work with an older 65 W or 45 W laptop I still use?

Yes. The adapter delivers 90 W maximum but automatically steps down to 75 W, 65 W, 60 W, 45 W, 36 W or 24 W to match the laptop's original requirement.

How can I confirm the DELL UB-90HB is operating correctly after I plug it in?

The adapter supplies a steady 20 V at up to 4.5 A (90 W) when the laptop draws full load; the laptop's charging indicator should light and the battery level must rise while the system runs.
