This 45 watt power supply delivers 19.5 volts at 2.31 amps through a 4.5 by 3.0 millimetre barrel connector. It replaces original Dell adapters such as the DA45NM131 and LA45NM140 across a wide range of Inspiron, XPS, Vostro and OptiPlex models.

Fits Dell Systems with 4.5×3.0mm Tip

The adapter accepts 100 to 240 volt AC input at 50 to 60 hertz for worldwide use. It powers compatible laptops directly and charges the internal battery while the system runs or sleeps. Verify that your device requires the 4.5 millimetre outer and 3.0 millimetre inner diameter tip before purchasing.

Steady Output During Continuous Use

Rated for 45 watts continuous delivery, the unit maintains the specified 19.5 volt output under sustained load without dropping voltage. It is not suitable for laptops that require the larger 7.4 by 5.0 millimetre connector or a higher wattage rating.
