  • Genuine Dell replacement keeps your laptop running safely

Genuine 90W Dell adapter

This genuine Dell LA90PM130 adapter supplies 90W at 19.5V 4.62A for compatible Dell Latitude and Inspiron notebooks. It accepts a worldwide 100-240V 1.7A input at 50-60Hz and includes a detachable power cord. The unit is new and has been tested for correct voltage, short-circuit and over-temperature protection.

Connector fit and use cases

The 7.5mm to 4.5mm barrel connector fits Dell models that require this specific tip size; buyers whose laptops use a different barrel diameter or a USB-C power port should look elsewhere. It is not suitable for higher-wattage workstations that demand more than 90W or for non-Dell brands with proprietary pin layouts.

Build integration

The adapter replaces a lost or damaged original charger and frees you from hunting for third-party units with unverified safety circuits. Its standard IEC inlet works with any compatible mains cord you already own, so no extra cable purchase is needed. The compact brick sits on a desk or travels in a bag without requiring special mounting or ventilation space.

Questions about this item

What AC wall socket voltage does the LA90PM130 adapter accept?

The adapter accepts 100-240V at 50-60Hz, so it works on standard mains supplies worldwide without a voltage converter.

Will the 7.5mm to 4.5mm connector fit my older Dell laptop that uses a 4.5mm barrel jack?

Yes, the 4.5mm end plugs directly into Dell laptops that require a 4.5mm barrel connector, while the 7.5mm end connects to the adapter brick.

How can I confirm the adapter is delivering the rated 90W after I plug it in?

The laptop should charge normally and report 19.5V 4.62A input in its battery or power management utility, matching the adapter’s rated output.
