Aetdin 45W 19.5V AC Adapter

The Aetdin 45W adapter supplies 19.5 volts at 2.31 amps for compatible HP laptops. It accepts a universal 100-240 volt input at 50-60 hertz. The connector measures 4.5 by 3.0 millimetres with a blue tip. This unit replaces original HP part numbers such as 719309-001 and 741727-001.

For HP Pavilion, Envy and Stream owners

Buyers needing a direct replacement for the listed HP models will find the correct voltage and tip size here. It suits Pavilion 15-ba and 15-f series, Envy X360 convertibles and Stream x360 11, 13 and 14 inch units. Users whose laptops require a different output voltage, higher wattage or a non-blue tip connector should look elsewhere.

Connector fit decides compatibility

The 4.5mm by 3.0mm blue tip is the single specification that determines whether this adapter fits your laptop. Match this exact connector size and the 19.5V 2.31A output against your device requirements before purchasing. A mismatch in tip geometry or electrical rating means the unit will not work.
