In recent months the ZMI brand has become one of the most prominent within the Xiaomi Youpin ecosystem. This is above all thanks to the continuous release of new really interesting and innovative smartphone accessories like the last one ZMI Speaker with Wireless Charging. Well, as you probably have already guessed, this time we are going to see a new gadget now on sale in China, the ZMI 20000mAh Bidirectional Power Bank.

The ZMI 20000mAh Bidirectional Power Bank comes with an eco-friendly external material in PC + ABS and a corrugated finish to improve the feeling in the hand and at the same time add a non-slip and scratch resistance function. In addition, ZMI has decided to further customize the device with a shiny metal logo.
As for the capacity of the power bank, as the name suggests, the accessory equips a 20000mAh battery. This will be enough to fully charge a Xiaomi Mi 9 for 4,7 times, an iPhone XS for 5,2 times and a Nintendo Switch for 2,8 times.
The power bank adopts two USB Type-A interfaces (the ordinary one) and a USB Type-C interface to charge up to 3 devices simultaneously. We then have the USB Type-C interface and the Micro-USB interface which support the current input for charging the power bank itself at the maximum power of 18W. With the bidirectional USB Type-C one, it can therefore recharge the power bank at 18W or recharge another device always at 18W.
This 18W fast charge will allow us to recharge a smartphone like the iPhone 11, through a Lightening to USB Type-C cable, reducing charging times by 53% compared to using the original charger and data cable that arrive with the iPhone 11.
If, on the other hand, you want to recharge low-power smart devices such as Bluetooth headsets or fitness bands, simply double-click the power button to activate the "low-power recharge" mode. With this charging mode the battery will be more protected as less stress is put on with a slower charge and there will also be better autonomy. Obviously the power bank can also be used in combination with other devices equipped with USB interface such as the ZMI USB fan and therefore become a small portable fan.
Finally, as regards safety, the ZMI 20000mAh Bidirectional Power Bank uses high precision sensors for the detection of resistance / capacity which not only makes it safer, but also improves the efficiency of the energy conversion rate and stabilizes the discharge voltage. It can also easily handle abnormal charging conditions such as overcharge, overdischarge, high temperatures, short circuits and much more.
The ZMI 20000mAh Bidirectional Power Bank is now on sale in China at the price of 149 Yuan, that is poco more than 19 euros.
