ZMI Power Bank Type-C QB910 10000 (QB910)

The Chinese flagship for the production of mobile electronics Xiaomi has been known on the market since 2010, but its gadgets have already won the sympathy of users in many countries around the world. The Power Bank 20000 is a new portable battery model released under the Zmi sub-brand. It has a capacity of 10,000 mAh, a USB-C port with support for fast charging (Power Delivery, Quick Charge) and stands out with an unusual design.

Best Design Award Winner

Perfectly even shapes, matte plastic that is pleasant to the touch, compactness and beautiful fabric upholstery of the battery itself: all this suggests that we have before us not just a useful gadget, but to some extent a fashionable accessory that you want to brag to your friends. Not without reason, in 2019, he received the award for the best design at the prestigious RedDot Awards. Of course, the fabric upholstery raises questions about practicality, but after a few weeks of testing, it did not rub or get dirty at all.

Strong middle peasant

As for the insides, this is a good, but missing stars from the sky, portable battery with a capacity of 10,000 mAh. Taking into account energy conversion losses and overall efficiency, the “net” capacity reserve available for replenishing the charge of mobile devices is about 6000 mAh. This is enough for one and a half charges of an average smartphone with a 4000 mAh battery. It is important to take into account that the output power is only 18 watts, which is not enough to fully charge the laptop. A conditional ultrabook like Chromebook Flip was charged exactly half in 2 hours, after which the energy supply in the battery ran out. But it, like some other power banks from Zmi, can work in USB hub mode, allowing you to connect a USB flash drive, portable drive and other peripherals to your laptop.
