Gallium Nitride (GaN) is a high-performance alternative to the traditional silicon used in charging devices. It features a wider band gap, which can sustain higher voltages and higher temperature. It is more heat-resistant, efficient, and carries current more quickly when compared to other semiconductors like silicon. The X.One GaN 6 Turbo charger feature GaN technology, hence providing faster charging capabilites and lesser energy loss due to excessive heat.
