The Dell 90W AC power adapter delivers 19.5V at 3.34A to power and charge compatible Dell laptops. This compact external adapter replaces an original power supply and provides a stable DC output through a standard barrel connector. Designed for everyday use, it supports charging during heavy workloads and includes built-in protection against overload and short circuits to help maintain reliable operation.

Advantages

The adapter provides a consistent 90W output that supports sustained laptop performance and battery charging. Its compact, lightweight design makes it easy to carry between home, office and travel locations. Integrated safety features reduce the risk of damage from overcurrent and overheating, while the standard barrel connector ensures wide compatibility with many Dell laptop models that use this connector type.

Suitable for

  • Powering and charging compatible Dell laptops at home or in the office
  • Replacing a lost or damaged original power adapter
  • Use with portable workstations during travel or commuting

How to use

Connect the adapter to the laptop’s DC input using the barrel connector, then plug the AC cord into a suitable mains outlet.
