45W Dell laptop charger

This 45W AC adapter delivers 19.5V at 2.31A through a 4.5mm by 3.0mm barrel connector. It accepts worldwide input of 100-240V at 50-60Hz and replaces part numbers including 0KXTTW and LA45NM140. The unit ships new with a power cord in non-retail packaging.

Suits owners of listed Dell models

It fits many Inspiron 11, 13, 14, 15 and 17 models plus XPS 11, 12, 13 and 15 units and selected Vostro and OptiPlex desktops. Buyers whose laptop requires a different voltage, wattage or connector size should look elsewhere. Anyone needing a battery rather than an AC adapter will not be served by this product.

Fits into a standard mains outlet

The wide-range input lets you plug into any household socket without a voltage selector. The fixed 4.5mm DC plug connects directly to the laptop, freeing you from carrying a separate transformer brick. No additional cables or configuration are required beyond the included power cord.
