This Fosi Audio GaN power adapter takes in input a voltage of 100-240VAC and allows to have in output a voltage of 48V DC for a maximum current of 5A. Its output connector is a DC 5.5/2.5mm jack.

Gallium nitride (GaN) is a very hard and mechanically stable wide bandgap semiconductor. With higher breakdown strength, faster switching speed, higher thermal conductivity, and lower on-resistance, power devices based on GaN significantly outperform silicon-based devices.
