45W AC adapter for Dell laptops

This 45-watt power supply delivers 19.5 volts at 2.31 amps through a 4.5mm by 3.0mm round connector. It is built for owners of compatible Dell Inspiron, Latitude, Vostro, XPS and Optiplex models who need a replacement or spare charger.

100-240V input and fixed 45W output

The unit accepts worldwide mains voltage from 100 to 240 volts at 50 to 60 hertz and draws 1.3 amps. Its output is locked at 45 watts, so it will not power systems that require the 65-watt 19.5V 3.34A variant.

Replaces lost or faulty 45W Dell chargers

It substitutes an original Dell 45-watt adapter with the same voltage, current and connector dimensions. The upgrade is worthwhile when the original unit has failed, been lost or a second charger is needed for travel; it is not suitable for laptops specified for higher-wattage power supplies.

Questions about this item

Should I pick the 45 W version or the 65 W version for my Dell?

Choose the 45 W unit only if your original charger is rated 19.5 V 2.31 A 45 W; the 65 W 19.5 V 3.34 A model is explicitly not compatible.

Will the 19.5 V 2.31 A output run my laptop at full speed?

Yes, 19.5 V at 2.31 A delivers the 45 W the laptop expects, so performance is not limited by the adapter.

Does the 4.5 mm × 3.0 mm barrel connector fit every Dell listed?

The 4.5 mm × 3.0 mm round tip matches the models shown; verify your original charger uses the same dimensions before ordering.
