What this adapter powers

The Graviton HSTNN-CA27 is a 150 W AC adapter built for HP ZBook 15 G3 and G4 mobile workstations. It also fits several Pavilion, Omen and 15-AX series notebooks that require the same 19.5 V 7.7 A output through a 4.5 x 3.0 mm centre-pin connector. Buyers who need a different voltage, a higher wattage or a barrel size other than 4.5 x 3.0 mm must choose another unit.

Input and output limits

The adapter accepts 100-240 V at 50-60 Hz worldwide and delivers a fixed 19.5 V at up to 7.7 A. The 4.5 x 3.0 mm plug with a centre pin is the only mechanical interface provided. Laptops that demand a different connector profile, a lower current limit or a proprietary communication pin will not work with this supply.

Deciding specification

The single figure that determines compatibility is the 150 W power rating combined with the 19.5 V 7.7 A output and the 4.5 x 3.0 mm centre-pin plug. If the target machine lists any other wattage, voltage, current or plug geometry, this adapter is not the correct replacement.
