Dell 90W 4.5mm Barrel AC Power Adapter

Dell 90W 4.5mm Adapter — Official Dell AC Power Adapter

The Dell 90W 4.5mm adapter is the official Dell 90W AC power adapter with the 4.5mm DC barrel connector. The 4.5mm barrel connector is Dell’s newer slim barrel format used on Dell Latitude, Inspiron and Vostro laptops that require a 90W power supply. Official Dell chargers deliver the exact output voltage and wattage that Dell’s power management system expects. This ensures the laptop charges correctly, reaches the correct battery charge rate and operates at full performance under heavy workloads that draw close to the full 90W available from the adapter. Third-party chargers may not communicate correctly with Dell’s power management system, potentially resulting in slower charging or charging warnings on the laptop.

Universal AC input from 100V to 240V on the Dell 90W 4.5mm adapter ensures compatibility with South African wall sockets and international power systems. A compatible South African plug configuration is included for direct wall socket connection. The stable regulated 90W output from the official Dell 90W 4.5mm adapter provides consistent power delivery to the laptop’s battery management system for safe and efficient charging throughout the adapter’s service life. Replacing a failed charger with the official Dell 90W 4.5mm adapter maintains the charging quality and system integration that Dell designed into the laptop.

Verify Before Ordering

Always verify that your Dell laptop requires 90W and uses the 4.5mm barrel connector before ordering. Check the wattage label on your original adapter. The 4.5mm barrel connector is a slim round connector — smaller than Dell’s older 7.4mm barrel connector. Browse Dell chargers from the Briggi Tech accessories range.
