90W Dell AC Adapter with 7.4mm Smart-Pin

This 90-watt AC adapter delivers 19.5 volts at 4.62 amps through a 7.4mm by 5.0mm barrel connector that includes a central smart-pin. It accepts a 100 to 240 volt input at 50 or 60 hertz, making it suitable for worldwide travel. The unit replaces Dell part numbers PA-10 and PA-3E for a wide range of Inspiron, Latitude, Studio and Vostro laptops. A detachable mains cable is included in the box.

For Dell owners needing a 90W replacement

Buyers with compatible Dell models that specify a 90-watt, 19.5-volt supply and the 7.4mm smart-pin connector will find this a direct fit. It will not suit Dell systems that require a higher-wattage brick or a different connector diameter. Users of non-Dell laptops or older Dell barrels without the centre pin should look elsewhere.

The 7.4mm by 5.0mm smart-pin connector decides fit

The critical specification is the barrel size: 7.4mm outer diameter, 5.0mm inner diameter with a central smart-pin. If the original Dell charger shows those exact dimensions and a 90-watt rating, this adapter matches. A different pin layout or wattage requirement means the part will not work.

Questions about this item

Will the 90W rating actually run my Dell laptop under load?

The adapter delivers 19.5V at 4.62A for a maximum of 90W, matching the original Dell PA-10 and PA-3E specifications, so it will power compatible Inspiron, Latitude, Studio and Vostro models at full speed.

Does the 7.4mm x 5.0mm barrel with centre pin work on every Dell charger port?

The plug has a 7.4mm outer diameter, 5.0mm inner diameter and a central smart-pin, which is the exact Dell proprietary interface used on the listed Inspiron, Latitude, Studio and Vostro series.

What do I need to mount or connect this adapter to my laptop?

The package includes the AC adapter and a detachable mains power cable; the DC lead ends in the 7.4mm x 5.0mm barrel with centre pin that plugs directly into the laptop’s charging socket.
