Replacement 90 W AC adapter

This 90 W AC adapter replaces Delta ADP-90CD DB and ADP-90SB series units for compatible notebooks. It accepts 100-240 V input at 50-60 Hz and delivers 19 V at 4.74 A through a 5.5 mm × 2.5 mm barrel connector. The three-prong outlet plug fits standard mains sockets. Buyers who need a higher-wattage supply or a different tip size cannot use this adapter.

Simple plug-in installation

Connect the barrel tip to the laptop power jack and the three-prong cord to a wall outlet; no drivers or configuration are required. Verify that the original part number appears in the compatibility list before ordering. A mismatched tip diameter or voltage will prevent the unit from powering the notebook correctly.

Steady 90 W output under load

The adapter maintains its rated 90 W output during continuous operation thanks to the 19 V 4.74 A design. Built-in protection circuits guard against over-voltage, over-current and short-circuit conditions. Users running sustained workloads will see stable power delivery without the voltage sag that occurs on undersized chargers.

Questions about this item
