With a new material called Gallium nitride (GaN), semiconductor components have been able to be shrunk down, leading to smaller than ever charging accessories. Several accessory makers have been taking advantage of GaN technology for new products, including Anker.

Anker recently debuted the PowerPort Atom PD 1, a 30W USB-C charger that's much smaller than the USB-C power adapters offered by Apple and, in fact, not much larger than an iPhone charger.
