Xiaomi ZMI QB810 10,000mAh Power Bank
The Xiaomi ZMI QB810 10,000mAh Power Bank is the smaller sibling of the QB820 20,000mAh. I bought it for about S$19 during the 12/12 sale. It weighs 177g and accepts input via either micro-USB or USB-C.

Xiaomi ZMI QB820 20,000mAh Power Bank
I hadn't realised ZMI is one of Xiaomi's ecosystem companies, supplying its power banks, batteries, and chargers. I came across the ZMI QB820 20,000mAh Power Bank through a friend's comment during the Razer Power Bank launch discussion.
