GaN is a new type of semiconductor material, widely used in aviation and military fields, with superior thermal conductivity efficiency, high temperature resistance and acid and alkali resistance, the charger made of it can not only achieve small size, light weight, but also in charging power conversion compared with the same power charger (non-GAN) has more advantages. GaN charger, a common form of 45 w, 65 w, 100 w, 120 w high power multi-port charger, especially suitable for home, office, business travel and other usage scenarios.
