The Xiaomi Mi PowerBank 2X comes with a PC/ABS environmentally friendly material. This plastic chassis has a matte surface. So we can say it provides the same non-slippery holding experience like the second-gen Mi PowerBank. It’s also scratch resistant. This model comes with dimensions of 13.55 x 6.76 x 2.39 cm and weighs 328 grams. In this sense, the PowerBank 2C is a bit bulkier than the Mi PowerBank 2.
It’s become a standard for high-end power banks, so the Xiaomi Mi PowerBank 2C comes with two USB ports as well as a micro USB port. Thus it supports bi-directional charging. The interfaces support 5.1V / 2.4A, 9V / 2A, and 12V / 1.5A with the maximum power of 18W. But this option can be used for only one port at a certain moment. This means when a single device is charging from one port, the Quick Charge 3.0 is enabled for it and disabled for the second one. It will take up to 8 hours to fill the battery fully.
Finally, the total capacity is 20.000mAh, but the actual output capacity is 13.000mAh due to the improved conversion rate of 93%. This capacity is sufficient for charging the Xiaomi Mi 5X for 4.3 times or the Xiaomi Mi MIX 2 for 3.8 times. The Xiaomi Mi PowerBank 2C comes with temperature protection, short circuit protection, input overvoltage protection, and a power display button to show the current power status once is tapped.
