What this adapter does

This 45 W AC adapter delivers 19.5 V at 2.31 A through a 4.5 x 3.0 mm centre-pin connector. It replaces Dell part numbers such as LA45NM140, DA45NM140, 03RG0T and 044PV8 for Inspiron 11 3000, 15 7000 and Latitude 13 7350 models.

Input and plug limits

The unit accepts 100-240 V at 50-60 Hz, so it works on mains worldwide when paired with the appropriate EU, US, UK or AU power cord. Output is fixed at 19.5 V and 2.31 A; it cannot supply higher current or a different voltage for other devices.

Deciding specification

The 4.5 x 3.0 mm plug with a centre pin is the single detail that determines compatibility. If the laptop requires a different barrel size or pin arrangement, this adapter will not fit.
