45 W 3-Prong AC Adapter US Black

This Dell 492-BBHO adapter delivers 45 watts of power through a standard three-prong US plug. It accepts a worldwide AC input range of 100 to 240 volts at 50 to 60 hertz and provides a DC output of 19.5 volts at 2.31 amperes. The unit comes in a black finish and is sold new.

Ideal for compatible Dell laptops requiring 45 W

Owners of Dell notebooks that specify a 45-watt, 19.5-volt adapter with a matching barrel connector will find this a direct replacement. Buyers whose laptops require a different voltage, a higher wattage rating, or a proprietary connector shape should look for the unit specified by their device manufacturer.

DC output 19.5 V 2.31 A determines compatibility

The critical specification is the 19.5-volt, 2.31-ampere DC output that yields the rated 45 watts. Only laptops designed for this exact voltage and current combination will operate correctly and charge the battery as intended.

Questions about this item

How can I verify the Dell 492-BBHO adapter is delivering the correct 19.5V and 2.31A output after connecting it?

The laptop battery icon should show charging and the system power meter will report the adapter wattage once the barrel plug is seated firmly.

What comes in the box with the Dell 492-BBHO 45W unit and is a separate power cord required?

The package includes the adapter brick with fixed 3-prong US mains plug and integrated DC cable; no extra cord is needed.

The specs list 45W at 19.5V — how do I know this capacity matches my Dell laptop?

Check the original charger label; if it shows 19.5V and 2.31A or 45W with the same barrel connector, this adapter is the direct replacement.
