90W Dell Inspiron AC Adapter

This 90-watt AC adapter supplies 19.5 volts at 4.62 amps through a 7.4 by 5.0 millimetre barrel connector. It accepts a 100 to 240 volt input at 50 or 60 hertz and ships with a US-standard power cord. The unit is built for Dell Inspiron 13, 14, 15 and 17 series laptops across the 3000, 5000 and 7000 families as well as selected Chromebook models.

Replaces original Dell 90W chargers

It serves as a direct replacement for a lost or damaged factory adapter on the listed Inspiron and Studio models. The jump is worth it when the original brick no longer holds a charge, the cable has frayed, or a spare is needed for travel. Buyers whose laptops require a higher wattage or a different connector diameter cannot use this adapter.

Simple plug-and-play installation

No drivers or configuration are required; connect the barrel tip to the laptop and the cord to a wall outlet. The most common issue is ordering the wrong tip size, so verify the 7.4 by 5.0 millimetre specification against the device before purchase. A loose fit or reversed polarity will prevent charging and may trigger an error.

Questions about this item

What connector size does this 90 W adapter use for the laptop side?

The DC plug measures 7.4 mm outer diameter by 5.0 mm inner diameter.

How do I connect the adapter to mains power and what is the common mistake?

Plug the supplied US-standard cord into a 100-240 V 50/60 Hz outlet, then insert the 7.4*5.0 mm tip firmly until it seats; the frequent error is leaving the tip partially inserted.

When should I consider replacing this charger?

Replace it if the output no longer delivers 19.5 V at 4.62 A, the cable shows exposed conductors, or the connector becomes loose on the laptop port.
