Purpose-built power

The Dell 5GT3K Slim AC Adapter delivers 90 watts at 19.5 volts and 4.62 amperes through a 7.5 mm barrel tip. It is designed specifically for select Dell Latitude laptops that require this exact voltage and connector size. The unit ships as the adapter only; a mains lead is not included.

Right fit, wrong fit

This adapter suits owners of compatible Latitude models needing a replacement or spare 90 W unit with the 7.5 mm barrel. It will not work for laptops that demand a different wattage, voltage, amperage or tip diameter, nor for devices that use USB-C Power Delivery instead of a barrel jack.

Build integration

The slim form factor leaves more space in a bag or dock alongside the laptop. Because the power cord is sold separately, you can pair it with any IEC C5 or C7 lead that matches your region’s wall socket. The fixed 19.5 V output means the laptop’s own charging circuitry handles all power negotiation.

Questions about this item

Which Dell Latitude models accept the 7.5 mm barrel tip on this 90 W adapter?

The adapter is built for select Latitude notebooks that require a 7.5 mm barrel connector at 19.5 V and 4.62 A; check your laptop’s service tag or original charger label to confirm the same tip size and power rating.

Can I use this slim 90 W unit with an older Latitude that shipped with a bulkier 90 W brick?

Yes, provided the older system also uses a 7.5 mm barrel jack and expects 19.5 V at 4.62 A; the slimmer housing does not change the electrical interface.

How do I verify the adapter is delivering the rated 90 W after I plug it in?

In Windows, open the battery icon or Dell Power Manager — it should show “19.5 V” and “4.62 A” (or roughly 90 W) while the battery charges; the LED on the barrel tip will also stay solid when power is flowing correctly.
