Product Overview

Dell 65W "Blue Pin" Adapter (19.5V, 3.34A)

4.5mm x 3.0mm Slim Pin Laptop Power Adapter

ADAPTER

The Dell 65W "Blue Pin" Adapter (19.5V, 3.34A) is the standard power supply for a wide range of modern Dell laptops manufactured in the mid-2010s and later. Rated at 65 watts, it provides sufficient power for ultrabooks, 2-in-1 convertibles, and standard Inspiron models featuring Intel Core i3/i5/i7 processors.

? Connector Identification: "Blue Pin" (4.5mm x 3.0mm)

The term "Blue Pin" is critical for compatibility. Dell has transitioned through several connector types. This 4.5mm x 3.0mm connector is physically thinner than older standards and is often, but not always, tipped in blue plastic.

Connector Type	Size	Common Tip Color	Typical Use
"Blue Pin" (Slim)	4.5mm x 3.0mm	Blue (or Black/Grey)	Modern Inspiron, XPS, Latitude
"Big Pin" (Old)	7.4mm x 5.0mm	Black	Older Inspiron, Vostro, Latitude
USB-C	Type-C	N/A	Latest Dell laptops

Important: The 4.5mm x 3.0mm "Blue Pin" connector is physically smaller and will NOT fit the older 7.4mm "Big Pin" port. Always verify the connector size before purchasing.
