Power bank for the Chinese brand Xiaomi is manufactured by Zmi. The model is made of plastic, has a compact size (slightly larger than a 5.5-inch smartphone), and is available in two colours: black and white.
Three connectors
At the end of the Xiaomi Zmi Power Bank 20000, there are a pair of USB A ports and one USB type C, which works both for input and output. The latter connector supports Qualcomm Quick Charge 3.0 and USB Power Delivery. With it, you can quickly charge the power bank. So, using a charger with Quick Charge 3.0 support, this will take 5.5 hours, and with USB Power Delivery charging, 3 hours and 20 minutes.
Simultaneously charge up to three devices
About 12,000 mAh out of a total of 20,000 mAh is available to power connected gadgets. Up to 3 devices can be charged at the same time, including smartphones, tablets and modern laptops with USB Power Delivery (via USB type C), including Asus Zenbook, HP Specter, Macbook Pro series, Dell XPS and more. Powerful laptops will only charge when the workload is minimal or turned off, while models with power up to 45W will charge without any restrictions at all.
Each of the ports individually supports fast charging of connected gadgets. In addition, you can simultaneously charge the Xiaomi Zmi Power Bank 20000 itself, and two more devices that are connected to it.
Additional features
Power bank can be used as a USB 2.0 hub when connected to a laptop or desktop PC. Through an accessory, you can connect a mouse, flash drive, hard drive to a computer, and these devices will be powered by Xiaomi Zmi Power Bank 20000. When you connect a laptop via USB type C, both laptop charging and the hub function will work.
A multi-level protection system is also provided. In case of overheating, exceeding the permissible voltage or current, short circuit and other overloads, the power bank will automatically turn off.
Zmi Power Bank 20000 is one of the most functional external batteries on the market, for which they ask for solid money. For example, the "younger brother" Xiaomi Mi Power Bank 20000, the name of the same capacity, costs almost half as much.
