The Dell 90W Original Charger (7.4×5.0mm) is the tried-and-tested power adapter for a massive installed base of Dell Latitude, Vostro and Inspiron laptops sold in Pakistan over the past decade. At Rs. 3,699, this is one of the sharpest Dell 90W barrel charger prices in Pakistan 2026 for a genuine OEM-grade unit — sold new and bench-tested at N.N Laptops, Shop 66A, 3rd Floor, Hafeez Center, Gulberg III, Lahore. If your Dell shows the "AC adapter wattage and type cannot be determined" message, replacing with a confirmed OEM-spec unit like this is the right fix.

OEM Chip & Protection
The embedded ID chip communicates with Dell's EC firmware so the laptop displays the correct wattage and does not fall back to slow-charge mode. Over-voltage, over-current and thermal protection circuits ensure the adapter cannot damage your laptop's charging port or battery even on poor-quality local power. A counterfeit or generic brick without the ID chip will often trigger Dell's "unable to determine adapter" warning and throttle CPU performance.
