Genuine Dell 90W AC adapter

This genuine Dell AC adapter delivers 19.5V at 4.62A for a total of 90W. It is designed for Dell laptops that require this exact voltage and current rating. The unit is supplied new and matches the original manufacturer specification.

90W output for compatible Dell laptops

The 90W capacity comfortably powers and charges supported Dell notebooks during typical workloads. It will run out of headroom if the connected system demands more than 90W under heavy load. Verify your laptop's required wattage before purchase.

Standard thermals and silent operation

In normal use the adapter operates within expected thermal limits for a 90W brick. It has no moving parts so it runs silently. Power draw from the wall matches the load placed on the laptop up to the 90W maximum.

Questions about this item

Will the 90W 19.5V 4.62A adapter charge a Dell laptop that originally came with a lower-wattage charger?

It supplies 90W at 19.5V and 4.62A; if the laptop accepts that voltage and the barrel connector fits, it will charge.

How can I verify the 0U7809 unit is delivering 19.5V and 4.62A after I plug it in?

Check the Dell power-status LED or BIOS adapter field — both should report a recognised 90W Dell adapter.

Does the box include the AC mains lead or only the 0U7809 brick?

The listing covers the adapter brick only; a compatible IEC C5 or C7 mains cable must be sourced separately.
