45W Dell Laptop Charger

This 45-watt AC adapter delivers 19.5 volts at 2.31 amps for a wide range of Dell Inspiron, XPS, Latitude, Optiplex and Chromebook models. It replaces original Dell part numbers such as DA45NM131, LA45NM140 and ADP-45XD BA. The barrel connector measures 4.5 by 3.0 millimetres, so buyers must verify the tip size before ordering. It is intended for users who need a direct replacement for a lost or faulty OEM charger.

Thermals and Power Draw

The unit accepts a universal 100 to 240 volt input at 50 to 60 hertz, making it suitable for worldwide travel without a voltage converter. It carries CE, FCC and RoHS certifications, indicating compliance with standard safety and emissions limits. No fan is present, so operation is silent. The adapter runs at typical efficiency for a 45-watt switch-mode supply under normal load.

Included Cable and Support

A detachable mains power cord is included in the package, allowing immediate use with a local wall socket. The supplier provides a 30-day unconditional refund period and 12-month warranty coverage, backed by 24/7 email support. No additional software or drivers are required. Buyers who need a higher wattage unit or a different connector tip should look elsewhere.

Questions about this item

How do I connect the 4.5*3.0mm tip to my Dell XPS 13 9350, and what is the common mistake?

Align the 4.5 mm outer diameter and 3.0 mm inner pin with the laptop's DC jack, then push straight in until it seats firmly. The common mistake is forcing the connector at an angle, which can bend the centre pin or damage the jack.

Which part of this 45W adapter will need replacement first under daily use?

The detachable mains lead (IEC C7 figure-8 cable) typically wears out before the brick because its flexible jacket and plug contacts endure repeated bending and plugging. The brick itself has no moving parts and runs cool at 45W.

What limits continuous output during a long charging session?

The 45W rating (19.5V at 2.31A) is the hard ceiling; if the laptop demands more current, the adapter will hit its current limit and either throttle or shut down to protect itself.
