Gallium Nitride chargers: Lots of power in a small package

Malcolm Owen for AppleInsider:

USB C Charger [GaN Technology], Anker 30W Ultra Compact Type-C Wall Charger with Power Delivery, PowerPort Atom PD 1 for iPhone, iPad, iPad Pro, MacBook, and moreChargers using gallium nitride are starting to enter the market, capable of delivering high quantities of power to devices while staying a reasonable size, and even taking up less space than conventional chargers. AppleInsider explains what’s changed in chargers, and how it can help redefine the accessory industry…
For phone and device chargers, the use of the high-voltage GaN means more power can be transferred at a far higher efficiency than silicon, making them more suitable for this sort of application.
Since more power can be shifted through GaN components, which can also be made more compact than their silicon counterparts, this means that more can be built into the GaN component instead of relying on multiple silicon components, shrinking the amount of components required for a charger, and potentially allowing for the overall size of the charger to be smaller.
To consumers, they can expect GaN chargers to be smaller in stature than current-generation chargers, as well as some that keep the same size but offer the ability to provide power to more devices, as well as being able to charge high-Watt items like MacBooks with ease.

MacDailyNews Take: We use and recommend the Anker USB C Charger with GaN technology, which offers 30W in an ultra compact Type-C wall charger which delivers high-speed charging to Apple iPhones, iPads, and MacBooks.
