65 W 7.4 mm adapter for Dell Inspiron

This 65 W AC adapter delivers 19.5 V at 3.34 A through a 7.4 mm barrel connector with a 5.0 mm centre pin. It replaces the original charger for a wide range of Inspiron 14, 15 and 17 series notebooks as well as selected Vostro models. The unit accepts 100–240 V input at 50/60 Hz for worldwide use.

Capacity and headroom

Rated at 65 W, the adapter comfortably powers mainstream Inspiron laptops during everyday workloads such as office applications, web browsing and video playback. It will reach its limit when the system draws sustained peak power from high-performance CPU or GPU states, at which point the laptop may throttle or drain the battery despite being plugged in.

Thermals, noise and power draw

The brick runs silently with no moving parts and stays warm to the touch under normal load. Typical efficiency meets CE, FCC and RoHS requirements, so idle draw remains low when the laptop is fully charged or in sleep mode. No fan noise or coil whine is specified for this model.

Questions about this item

Will the 7.4 mm tip fit the Dell Inspiron 15 5521 I am keeping?

The adapter uses a 7.4 mm outer diameter and 5.0 mm inner diameter tip, which matches the Inspiron 15 5521 listed in the compatibility table.

How can I verify the charger is delivering 19.5 V at 3.34 A after I plug it in?

The brick is rated for 19.5 V 3.34 A output; a multimeter on the barrel connector should read 19.5 V with the unit powered and no load applied.

Does the package include a mains lead or only the power brick?

The package content lists one AC adapter unit; a separate IEC C5/C7 mains cable for your region is not included.
