45W Dell AC Adapter

The myVolts 45W power supply delivers 19.5V at 2.31A through a 4.5mm barrel connector. It replaces original Dell adapters carrying part numbers such as 05NW44, HK45NM140 and ADP-45XD. The unit accepts 100-240V AC input at 50-60Hz for worldwide use.

Sustained 45W output

Continuous operation at the rated 45W is supported by the 19.5V 2.31A DC output. The adapter maintains stable voltage across the listed Dell Inspiron, XPS, Latitude, Vostro and OptiPlex models during extended charging sessions. No thermal throttling or derating is described in the specifications.

4.5mm barrel fit

The decisive specification is the 4.5mm x 3.0mm connector diameter. Only laptops requiring this exact barrel size and the 19.5V 2.31A profile will work correctly. Buyers whose devices use a different connector diameter or a higher current rating cannot use this adapter.

Questions about this item

How much heat does the 45W 19.5V adapter produce during all-day use?

The adapter draws 1.1A at 100-240V input and delivers 19.5V at 2.31A. Typical efficiency for this class keeps the brick warm but not hot under continuous load.

What must I already own for this 4.5mm Dell charger to work?

You need a Dell laptop that accepts a 4.5mm x 3.0mm barrel connector and requires 19.5V at up to 3.34A. Compatible models include Inspiron 11-3000, 13-5000, 14-3000, 15-5000, XPS 13 9333, 9343, 9350, Latitude 13 7350 and Vostro 14 3458.

Will this 45W unit run an older Dell that shipped with a 65W brick?

If the older system is listed — such as Inspiron 15-3000 3551, XPS 12 L221X or Latitude 14 E5450 — the 45W supply will power it. On unlisted models the lower wattage may limit performance or prevent charging.
