AC Adapter, 240W, 19.5V, 3

The Dell 450-AAJI is a 240.0 W AC adapter for laptop charging. It supplies 19.5 V at 12.3 A through a cable to the computer’s charging connection. Its slim black body is a separate external power unit for a desk or workstation.

The round output plug has a center pin, with a 7.4 mm outer diameter and 5.0 mm inner diameter. These measurements help identify the connector format when checking compatibility. The attached output lead is approximately 1.75 m long, allowing the adapter to sit apart from the laptop while connected to a power source.

Its input is rated for 100–240 V AC at 50–60 Hz. The 450-AAJI is for compatible Dell laptop charging setups that use these electrical ratings and a round center-pin connector.
