The popular Xiaomi brand Power bank is a high-capacity (20,000 mAh) external lithium polymer battery that supports various fast charging standards. So, in addition to Quick Charge 3.0 and 2.0 technology, the proprietary protocols of Samsung, Huawei and MediaTek (Pump Express) are supported here, which expands the range of gadgets that the Xiaomi Zmi Power Bank Aura 20000 (QB821) power bank will quickly “charge” with energy.

Fast charging also works to replenish the capacity of the device itself, therefore, via USB-C in Power Delivery mode, it will take less than 6 hours to restore a full battery charge. The real capacity of the model, which can be "given away" to mobile devices, is 12,600 mAh. This, for example, is enough for several charges of modern smartphones or portable speakers. You can charge 2 devices at the same time.

Support for microcurrent charging is also announced, which means that the device is also suitable for owners of small devices, including smartwatches, fitness trackers or Bluetooth headsets. The appearance of the battery deserves special mention. The case is made of durable plastic and is complemented by an LED display that displays digital values (percentage of power bank charge).

Video reviews

Xiaomi and its subsidiaries are almost out of competition in the portable battery segment. The brand's products stand out from their peers with a large real capacity at a very democratic cost. The best confirmation of this in fact is the Zmi Power Bank Aura 20000 (QB821).

Quartet of connectors

The power bank is assembled in a case of a traditional form factor, the materials for which were soft-touch plastic that is pleasant to the touch. Connection connectors lined up on the upper end of the device: two USB A output ports (provide a total power of up to 18 W) and two microUSB / USB-C input connectors. Through the contacts of the latter, the power bank charges at an accelerated pace of 18 W — from zero to hundreds of percent in about 6 hours .

Fast Charging Protocols

Xiaomi Zmi Power Bank Aura 20000 (QB821) works on Qualcomm Quick Charge second and third generation, MediaTek Pump Express, Samsung Adaptive Fast Charging and Huawei Fast Charge fast charging protocols. Of the 20000 mAh of its claimed capacity, the user has the right to count on 12600 mAh, which is also by no means small. The difference in performance occurs due to the conversion of the operating voltage from 3.7 to 5 V and other losses during the operation of the power bank.

2-in-1 cable

The remaining charge level of the power bank is displayed on the info display in the upper part of the front panel of the case. Also, an arrow indicates the charging of a mobile battery or gadgets from the outside. Out of the box, the model comes with a USB A — microUSB cable with a built-in adapter for a symmetrical USB-C connector. Owners of devices with different charging connectors do not have to carry a bunch of wires with them.
