What it is and who it replaces

The Graviton FSP090-ABBN2 is a 90 W AC adapter that delivers 19 V at 4.74 A through a 5.5 x 2.5 mm barrel connector. It ships with a power cord and accepts 100-240 V input at 50-60 Hz, making it a direct replacement for the listed FSP and PA part numbers across multiple laptop families.

Practical limits of the 90 W barrel interface

The unit is fixed at 19 V output and cannot negotiate other voltages or higher currents. Devices that require more than 90 W, a different voltage rail, or a USB-C Power Delivery handshake will not operate from this adapter. The 5.5 x 2.5 mm plug fits only matching jacks; centre-pin or smaller-diameter sockets are incompatible.

When the jump to this adapter is worth it

Choose this supply when the original charger is lost or damaged and the laptop part number appears in the compatibility list. It is not suitable for systems that draw above 90 W under load, for thin-and-light models that charge exclusively over USB-C, or for any device specifying a voltage other than 19 V.
