45 W Dell AC Adapter

This 19.5 V 2.31 A power supply replaces the original charger for a wide range of Dell Inspiron, XPS, Latitude, Vostro and OptiPlex laptops. It accepts 100 to 240 V input for worldwide use and terminates in a 4.5 mm by 3.0 mm barrel tip.

Sustained 45 W delivery

The adapter maintains its rated 45 W output continuously rather than only in short bursts, so the laptop charges while under load without throttling. A broad 50 to 60 Hz input tolerance keeps output stable on varying mains supplies.

Simple plug-and-play fit

Installation requires only matching the 4.5 mm by 3.0 mm connector to the laptop port and plugging the included power cord into the wall. The most common issue is ordering the wrong tip size; the 7.4 mm by 5.0 mm variant looks similar but will not fit.

Questions about this item

Does the 45 W adapter get noisy or hot when it runs all day?

The unit has no fan and relies on passive cooling; the 19.5 V 2.31 A output stays within its 45 W rating during continuous use.

What else must I already own for this charger to work?

You need a compatible Dell laptop with a 4.5 mm × 3.0 mm barrel jack and the supplied IEC C5 mains cord for wall power.

Will the 4.5 mm × 3.0 mm tip fit my older Dell XPS 13 9343 alongside newer Inspiron models?

Yes, the connector matches the 9343 and the listed Inspiron 3000, 5000 and 7000 series that use the same barrel size.
