What this adapter powers

The Delta ADP-90CR B is a 90W AC power adapter that delivers 54V at 1.67A through a 5.5x2.5mm barrel connector. It suits devices requiring this exact voltage and current, such as certain monitors, docking stations or small-form-factor PCs. A detachable power cord is included for immediate use.

Replacing a lost or faulty unit

This adapter replaces an original Delta 90W supply that has failed, been misplaced or shows cable damage. The jump is worth it when the original charger no longer holds a stable 54V output or the connector fits loosely. It restores reliable power without changing the device's power profile.

Check voltage, current and connector first

Before ordering, verify the device label states 54V and 1.67A (or 90W) and that the jack accepts a 5.5x2.5mm plug. Confirm the input range 100-240V 50-60Hz matches your mains supply. Overseas buyers should note the power cord may not be included and a local cord will be needed.
