Replacement 45W Dell adapter

This 45-watt AC adapter replaces original Dell chargers for a wide range of Inspiron and XPS ultrabooks. It delivers 19.5 volts at 2.31 amps through a 4.5 mm barrel connector and accepts 100 to 240 volts AC input for worldwide use.

Build integration and safety

The unit connects directly to the laptop’s DC port and includes a detachable mains cord, so no internal work or extra cables are required. Built-in protection guards against short circuits, overvoltage, overcurrent and internal overheating, and the design meets recognised North American electrical-safety standards.

Upgrade context and limits

It suits owners whose original 45-watt adapter has failed or been lost and who need a direct, safety-tested replacement with the same output rating. Buyers whose laptops demand a higher-wattage supply or a different connector type will need a different unit.
