Huge capacity to meet all your power needs on-the-go

The Xiaomi ZMI 20000mAh Power Bank QB820 consists of six premium quality LG 18650 lithium-ion battery cells. It has enough power to keep your devices charged during long-distance business travels, cross-country trips or just day to day life, when being tied down to a power outlet is not an option. With portable power, you’re connected at all times.

Create a portable office

The 20000mAh Power Bank provides 2 devices in 1. Not only a portable charger, it also has a USB hub mode (USB 2.0 compatible) that delivers data transfer over its USB ports. In addition, the USB hub mode is perfect for powering your smaller devices that will require a smaller charging current. These may include a smart watch, Bluetooth headphones and other wearables. It cleverly recharges via the USB PD or Quick Charge fast-charging protocols as well as via a conventional power plug.

Super fast recharging

The power bank 20000 supports the new USB Power Delivery (PD) 2.0 protocol through its USB Type-C port with a maximum input power rating of 45 watts. Using a USB PD enabled power adapter, rated 45 watts or higher, the built-in battery will charg in a mere 3.8 hours.

Two-way fast charging

The power bank 20000 supports two-way fast charging, meaning that it charges your mobile devices whilst also being charged itself – all at super high speed.

Triple output can charge 3 mobile devices at the same time

The Xiaomi ZMI 20000mAh Power Bank QB820 accommodates your need to charge multiple devices at the same time. Two USB-A ports are capable of Quick Charge 3.0 fast charging up to 5V/2A, 9V/2A and 12V/1.5A output. One USB-C port is enabled for USB PD and Quick Charge 3.0 with a maximum output power rating of 45 watts.
