It’s a 27W USB-C PD charger that’s the size of the junky 5W plug that Apple gives you for free with your iPhone. > Anker says that the difference with the Atom series of chargers is the use of Gallium Nitride (GaN) components over silicon, which the company says allowed for increased efficiency and the dramatically smaller size. The company also says the Atom PD 1 will be the first in a line of Atom chargers, with a 60W, two USB-C port PowerPort Atom PD 2 charger and a 100W four port (two USB-C and two USB Type-A) PorwerPort Atom PD 4 charger on their way, too.
