Xiaomi Alkaline Batteries comes in AA and AAA. Interesting fact, in China, AA is known as No. 5 and AAA is known as No. 7.
Both sizes come in a pack of ten and each pack retails for CN¥9.90 (S$2). That works out to be only S$0.20 for each battery.
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).
I bought the Xiaomi High Speed Wireless Charger Set for CN¥149 (S$30). It includes the 27W USB-A to USB-C charger and 20W Wireless Charger.
