Compatible Dell Models

This 90 W AC adapter replaces the original charger for a wide range of Dell Inspiron, Latitude, Precision and Studio notebooks. Supported models include Inspiron 11z, 13, 13R (N3010), 14 (1440), 14 (1464) and 1420, plus Latitude D400 through D505 and Precision M65 through M4500.

Thermals Noise Power

The adapter delivers 90 watts of continuous power to charge the battery and run the laptop simultaneously. It operates on standard AC mains voltage and uses a lithium-ion compatible charging profile. No active cooling fan is present, so operation is silent under normal load.

Connector Build Day To Day

A barrel-type DC plug fits the charging port on every listed Dell model without an adapter. The cable length allows comfortable desk or bedside use while the unit sits on the floor. Sturdy strain relief at both ends resists damage from frequent plugging and unplugging.

Not For Other Brands

This unit only fits the Dell models listed above; it will not charge laptops from other manufacturers or Dell models outside the compatibility list. Buyers needing a charger for a different device must source the correct part for that machine.

Questions about this item

How do I connect the 90W adapter to my Inspiron 14 (1440) and what step is often missed?

Plug the barrel connector firmly into the laptop's DC-in jack until it seats, then connect the AC cord to the brick and wall outlet; the step often missed is fully seating the barrel plug so the charge LED lights.

What part of this adapter will need replacement first with daily use?

The detachable AC power cord and the barrel-tip cable see the most flexing; replace either if the insulation frays or the connector becomes intermittent.

At what load does the 90W brick hit its thermal limit during sustained charging?

Continuous 90W output — such as charging a depleted battery while running a Precision M4500 at full load — will trigger thermal throttling first.
