The new power bank has a 10000mAh battery capacity and has four ports. The ports include two full-sized USB ports, a MicroUSB port, and a USB-C port. The selling point of the power bank is its small size which the manufacturer says is half the size of a mobile phone and its support for 22.5W 2-way fast charging.

This means you will be able to charge a device at a maximum power output of 22.5W as well as the power bank itself. The USB-C port allows for two-way fast charging, so you can use the port to charge the power bank if you connect it to a charger that outputs 22.5W. The MicroUSB port also supports 22.5W input while each of the USB-A ports and the USB-C port has a maximum power output of 22.5W at a time. ZMI says charging the power bank takes 3.5 hours when using a 22.5W charger.

The MINI Power Bank will sell for ¥89 (~$13) and you can pick it up on JD.com, TMall, and on ZMI’s own online store.
