Dell laptop power adapter

This replacement adapter delivers 45 W or 65 W output at 18 V to 20 V with a 4.5 mm x 3.0 mm or 7.5 mm x 5.0 mm barrel plug. It supports a wide range of Dell Inspiron models from 11-inch to 24-inch series plus selected XPS, Latitude and Vostro laptops. The unit accepts 100 V to 240 V input at 50 Hz to 60 Hz for worldwide use.

Build integration and cable management

The adapter connects directly to a wall outlet and supplies power through a fixed DC cable ending in one of the two listed barrel connectors. Built-in IC protection guards against overload, short circuit and over-temperature conditions while shielded wiring resists electromagnetic interference. No extra cables or modules are required for basic charging.

Suitability and limitations

This unit suits owners of compatible Dell laptops needing a spare or replacement charger with the specified plug sizes and voltage range. Buyers whose devices require a different connector diameter, a USB-C power delivery profile or a higher wattage rating should look elsewhere. The adapter is not designed for non-Dell hardware or for powering peripherals beyond the laptop itself.
