DELL Adjustable DC Adapter Tip- 7.4 × 5.0mm

One Dell-compatible adapter tip with five selectable power modes.

Designed for compatible Dell and Alienware laptops with a 7.4 × 5.0mm charging port, this adjustable DC adapter tip supports 360W, 300W, 240W, 180W, and below 150W modes. The color-coded LED makes the current setting easy to identify, while the recessed button helps prevent accidental changes. The built-in memory function automatically saves the last selected mode.

Five Selectable Power Modes

Supports 360W, 300W, 240W, 180W, and below 150W modes. Select the appropriate setting based on the wattage of the laptop's original power adapter.

Dell 7.4 × 5.0mm Connector

Features a 7.4 × 5.0mm round connector designed for compatible Dell and Alienware laptops with the corresponding charging port. Please confirm your device's charging-port size before purchasing.

Supports Devices Up to 360W

The maximum 360W setting supports compatible high-performance gaming laptops, mobile workstations, and lower-power laptops. Also supports 150W chargers for compatible lower-power Dell and Alienware devices.

Color-Coded LED Indicator

Each power mode is identified by a different LED color for immediate at-a-glance confirmation of the active power setting. A steady white light after power-on indicates normal operation.

Recessed Button — Prevents Accidental Mode Changes

The adjustment button is recessed inside the circular opening of the DC adapter tip, helping prevent accidental setting changes during use, storage, or transport. Lightly press and quickly release to cycle through the five modes in sequence.

Power-Setting Memory

The adapter automatically remembers the last selected power mode and restores it the next time it is powered on — no need to reconfigure after each session.
