DELTA ELECTRONICS ADP-40PH BB 40W 19V 2.1A power adapter

Compact 40 W 19 V power adapter

The Delta ADP-40PH BB delivers 19 V at 2.1 A for devices that require a 40 W external supply. It accepts 100-240 V input at 50-60 Hz, making it suitable for worldwide mains voltages. The unit is intended as a direct replacement for the original charger supplied with compatible laptops or peripherals. Buyers who need a higher-wattage brick for larger systems should look elsewhere.

Passive cooling with built-in protection

The adapter uses a sealed plastic enclosure with no moving parts, so it runs silently in normal use. Internal safeguards protect against incorrect voltage, short circuit and internal overheating. The 1.2 A input draw at full load keeps heat output modest for a 40 W design. Users who require active cooling or fanless certification for noise-critical environments will not find those features here.

Includes detachable US power cord

A three-contact US AC cord is bundled, allowing immediate connection to North American outlets. Overseas purchasers should note that the cord is not supplied for international orders, so a local mains lead must be sourced separately. The barrel output connector is fixed and matches the original Delta specification. Anyone needing a different plug type or a longer cable will have to provide their own.
