It was my first time to Shanghai, China, for a business trip, and I decided to pop by the Mi Store (小米之家) at Pearl of the Orient (东方明珠) .
As standalone, the Xiaomi 20W Wireless Charger cost CN¥99 (S$20) while the 27W USB-A to USB-C charger costs CN¥49 (S$10). There is almost no difference in price by buying them in a set.
It measures 47 x 28 x 56 mm and is made from polycarbonate. Silicone rubber can be found at the top and bottom of the charger for anti-slip purposes.
Xiaomi 20W Wireless Charger is currently the world’s fastest wireless charger. It is compatible with any Qi devices but so far only the Xiaomi Mi 9  will be able to make use of the full 20W wireless charging speed.
At the back of the wireless charger is a USB-C port and it is designed to fit the included USB-C cable head. You might run into problems using other USB-C cables as the fitting is quite tight.
The charger is a 27W USB-A to USB-C charger that has Quick Charge 3.0 (QC3.0) and supports 110V – 240V.
Measuring at 47 x 28 x 56 mm and weighing 84 g, it is pretty compact.
Using QC3.0, the maximum input is 20V/1.35A, and the maximum output is 15V/1.33A. If not, it falls backs to 12V/1.35A for input and 12V/0.8A for output.
