Applications

The Dell PA-1 series AC adapter was the standard OEM charger supplied with Dell Inspiron and Latitude laptops of the early-to-mid 2000s, including models sold under the Dell XP Series branding. These adapters use a 3-pin Dell barrel connector and supply the 18.5V rail required by that generation of Dell notebooks. The universal 100–240V input means the adapter works on both North American and international power grids without a separate voltage converter. This is a practical direct-replacement or spare charger for anyone maintaining or using Dell laptops from that era.
