Beyond the massive 20000mAh capacity,It has two USB-A ports, a Micro-USD port and a USB-C port. You can only use the two USB-A ports to charge other devices, and the Micro-USB port to charge the powerbank. That said, the USB-C can go either way, allowing for extra flexibility there. The 20000mAh powerbank also supports 18W fast charging. There’s a caveat to this, though. The fast charging only works for single-port charging, so you won’t be able to charge multiple devices at the same speed. You’ll be able to find the Redmi 20000mAh powerbank at physical Mi Stores nationwide. They are priced at RM99. (Source: Xiaomi Malaysia / Facebook. Image: Xiaomi)
