Dell 331-7957 compatible 180 W adapter

This 180 W AC adapter delivers 19.5 V at 9.23 A and uses a 7.4 mm x 5.0 mm tip. It is built for Dell laptops that require the original 331-7957 part and ships in new condition.

The bundle supplies a mains cable so the unit can be plugged straight into a wall socket. Buyers who need a different tip size or a lower-wattage unit for ultraportable models will need a separate adapter.

Questions about this item

Does the 7.4 mm x 5.0 mm tip wear out and need replacement?

The barrel tip is a solid metal connector; it does not contain moving parts and normally lasts the life of the adapter unless physically damaged.

What limits continuous 180 W output — heat or the 19.5 V 9.23 A rating?

The 19.5 V 9.23 A rating defines the maximum continuous output; sustained loads at 180 W are limited by that electrical ceiling and the adapter's internal thermal design.
