Choetech 100W GaN Dual USB-C Charger is one of the latest products from Choetech. 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.
There are two plug variants for the charger, US and EU. Since I live in Singapore, so I chose the EU plug.
Besides the fact that the EU plug is bulky, the overall charger footprint is compact. 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.
As the name implies, it can output a maximum of 100W through USB-C Power Delivery (PD).
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.
This charger is slightly smaller than Apple’s 61W USB‑C Power Adapter.
My company’s 15″ MacBook Pro, macOS detected it as a 100W charger.
When charging, it takes in about 19.4V and between 1.5A and 2.74A.
The temperature of the charger hovers between 40°C and 50°C.
