It retails for **US$59.99 (S$86)** with free shipping to Singapore. This dual USB-C charger is powered by GaN, which stands for Gallium nitride. The technology allows the charger to have a smaller footprint by providing higher efficiency in charging. You can read more about GaN in The Verge’s [Gallium nitride is the silicon of the future](https://www.theverge.com/2018/11/1/18051974/gallium-nitride-anker-material-silicon-semiconductor-energy). There are two plug variants for the charger, US and EU. Since I live in Singapore, so I chose the EU plug.

Measuring 6.7 x 6.5 x 3 (cm) and weighing 195 g. The design is in matte white, which means it is not a fingerprint magnet. That is something I prefer compared to Apple’s glossy MacBook Pro charger.

Each of the two USB-C ports is capable of a maximum output of 5V/3A, 9V/3A, 12V/3A, 15V/3A, and 20V/5A. If both USB-C ports are in use, the maximum output of each port will be 5V/3A, 9V/3A, 12V/3A, 15V/3A, and 20V/2.25A. Like most chargers, it takes in AC 100 – 240V, so it is suitable to bring along for traveling.
