Anyone accustomed to the hefty MacBook power brick might want to sit down before they see the Anker Nano II 65W. This is far, far smaller than Apple’s wall charger, but can still put out 65 watts. The secret is gallium nitride.
Anker also introduced on Monday versions with 45W and 30W.
The chips in power adapters have been made with silicon since the early days of the computer age. Apple uses this material in all its offerings. But gallium nitride semiconductors are much more efficient. Anker embraced GaN years ago, and is now introducing its second-generation products.

“By improving the chips and the internal layout of these devices, we have created a line of Nano II chargers that transmit energy more efficiently, take up less space, and better regulate temperature than our previous generation,” said Anker.
The company promises the 65W version can charge a 2020 MacBook Air in less than 2 hours. And it can power a 13-inch MacBook Pro at full speed. They can also be used with iPhone or iPad.
Each of the chargers has a single USB-C port and a foldable plug. While the size varies between models, all are considerably smaller than Apple’s own MacBook charger.
