45 W AC adapter for Dell Inspiron

This 45 W AC adapter replaces the original charger for a wide range of Dell Inspiron laptops across the 3000, 5000 and 7000 series. It delivers 19.5 V at 2.31 A through a 4.5 × 3.0 mm barrel connector and includes a three-prong mains cord. The unit accepts 100–240 V input at 50/60 Hz for worldwide use.

Replaces a lost or faulty 45 W Dell charger

If your existing Dell 45 W power supply has failed, been lost or shows damaged cabling, this adapter restores full charging capability. The jump is worth it when the original unit no longer holds a stable connection or the brick overheats, provided your laptop uses the 4.5 × 3.0 mm tip and not the larger 7.4 × 5.0 mm variant used on some models in the same series.

Verify the barrel tip before ordering

Check the DC connector on your current charger or laptop port: it must measure 4.5 mm outer diameter and 3.0 mm inner diameter. Some Inspiron 3000, 5000 and 7000 models require the 7.4 × 5.0 mm tip instead, and this adapter will not fit those. Confirm the tip size visually or with a caliper to avoid an incompatible purchase.

Questions about this item

Will the 4.5x3.0mm barrel connector fit my Dell Inspiron 15-3000 series laptop?

The adapter uses a 4.5mm external and 3.0mm internal diameter tip. Most Inspiron 3000, 5000 and 7000 models use this size, but some require the larger 7.4x5.0mm tip. Verify the port on your specific unit before ordering.

What is the correct way to connect the 3-prong AC cord to the adapter brick?

Plug the supplied 3-prong mains cord firmly into the IEC socket on the adapter body, then insert the 4.5x3.0mm DC barrel into the laptop. The step users miss is seating the mains cord fully so the ground pin makes contact.

How long before the 45W 19.5V 2.31A output brick typically needs replacement?

A 45W adapter running at 19.5V and 2.31A usually lasts several years. Replace it if the DC cable frays near the barrel, the brick overheats, or the laptop stops charging while the LED remains lit.
