Replacement charger for Dell laptops

This 90W AC adapter delivers 19.5V at 4.62A through a 7.4 x 5.0 mm round connector. It supports a wide range of Dell Latitude, Inspiron, Studio, Precision and XPS models listed in the compatibility data. The unit accepts 100-240V input for worldwide use. Buyers needing a higher wattage supply or a different connector size cannot use this adapter.

Compact brick with detachable mains lead

The package includes one AC adapter and one AC power cable, so the brick separates from the IEC lead for easier packing. A 7.4 x 5.0 mm barrel plug fits the charging port on supported Dell notebooks without adapters. The housing is a standard black plastic enclosure built for daily transport. Users who prefer a fixed cable or a right-angled plug will find this design unsuitable.

Ready-to-use kit with spare cord

An extra mains cable is bundled, letting you keep one lead at a desk and another in a travel bag. No driver installation or configuration software is required; the charger works immediately on connection. The 30-day money-back period and 12-month coverage from the supplier apply to the complete kit. Customers wanting USB-C Power Delivery or multi-voltage tips must look elsewhere.
