  • Delivers 45W at 19.5V 2.31A output

4.5x3.0mm 45W AC Adapter for Dell Laptops

This 19.5V 2.31A power supply replaces Dell part numbers such as AA45NM131, DA45NM140 and LA45NM121. It accepts 100-240V input for worldwide use and ships with a detachable power cord. The 4.5mm by 3.0mm barrel tip matches the charging port on many Inspiron, Latitude, Vostro and XPS models.

Ideal for owners of listed Dell 11, 13, 14.

Buyers with Dell 15-3520, 3521, 3531, 3542, 3537 or Inspiron 15R-5520, 5521, 7520, N5010, N5110 cannot use this adapter because the connector differs. It also does not fit Dell 15-7557 or 15-7559. Anyone needing a 7.4x5.0mm tip or a higher wattage unit should look elsewhere.

4.5mm by 3.0mm barrel connector decides fit

The adapter only works when the laptop requires exactly this 4.5mm outer and 3.0mm inner diameter tip at 19.5V. Verify the original charger’s tip size and the Dell part number on the label before ordering. Mismatched dimensions will prevent charging even if the voltage appears correct.

Questions about this item

How much heat or noise does the 45W 19.5V 2.31A adapter produce when it runs all day?

The adapter has no moving parts and no fan, so it runs silently; its metal case dissipates the 45W load as mild warmth that stays within normal operating limits for a laptop supply.

What must I already own for this charger to work with my Dell?

You need a Dell laptop whose DC jack accepts a 4.5 mm outer / 3.0 mm inner barrel plug and that draws 19.5V at up to 2.31A — models listed include Inspiron 15 3000, 5000 and 7000 series, Latitude 12 7202, 13 3379, 14 E5450 and Vostro 3458, 3558, 5468.

Will this 4.5x3.0mm 45W unit work alongside the older 7.4x5.0mm Dell chargers I still have?

No — the 7.4 mm x 5.0 mm barrel is physically larger and electrically different, so this adapter cannot replace or share tips with those older supplies; it only fits the 4.5 mm x 3.0 mm jack found on the listed models.
