Anker Uses Gallium Nitride to Shrink High-Wattage Chargers

Anker today announced a new solution for charging battery-powered devices. The company has replaced silicon in the charging block with Gallium Nitride. Silicon components are larger and heavier than Gallium Nitride, and waste power due to heat emission. Switching to Gallium Nitride allows Anker to reduce the size of the charger while keeping the power delivery at a high wattage. The first product, called the PowerPort Atom PD 1, is just larger than a standard 5W charger and yet it delivers up to 27W via USB-C. Anker claims this is enough to charge most phones and tablets, as well as some gaming devices and even laptops. The PD 1 goes on sale in late November for $30. Anker intends to deliver 60W and 100W versions of the PD 1 with multiple ports in the months ahead.
