Universal 90W adapter with USB port

The DELL PA-1900SU-01BK delivers up to 90W through a 20V 11.8A DC output and includes a 5V 2.4A USB Type-A port for charging phones or tablets. It accepts 100V-240V AC input at 50-60Hz and comes with a 6-foot mains cord plus a set of interchangeable tips. The unit weighs 150 grams.

Swappable tips cover many brands

A connector kit supplies tips such as 4.8mm x 1.7mm and 5.5mm x 2.5mm sizes to fit HP, Dell, Lenovo, Asus, Acer, Toshiba, Samsung, Sony, Fujitsu and Gateway models listed in the compatibility table. Selecting the correct tip lets the adapter automatically provide 18.5V, 19V, 19.5V or 20V as the laptop requires. The USB port remains active while the laptop charges.

Slim corded design for travel

The compact brick measures 14.33in W x 12.83in H x 9.06in D and uses a fixed DC cable with a detachable AC cord, so only the mains lead changes between regions. Built-in protection guards against over-voltage, over-current, short-circuit and over-temperature conditions. Buyers needing a higher-wattage supply for gaming laptops or a USB-C Power Delivery port will need a different adapter.

Questions about this item

Does the 5.5 mm × 2.5 mm tip on this charger wear out and need replacing?

The T9/M5 tip uses a 5.5 mm × 2.5 mm barrel connector rated for 19 V 3.42 A; the tip set is replaceable if the barrel or pin becomes loose.

What limits the 90 W output when the adapter runs continuously?

The unit is rated for 85 W continuous DC output at 20 V 11.8 A; sustained loads above that will trigger the internal protection circuit.

How hot and loud does the brick get when it powers a laptop all day?

The adapter has no fan, so it runs silent; under full 85 W load the case becomes warm but stays within normal operating temperature for a sealed 90 W brick.
