ZMI, one of the first Xiaomi-funded ecosystem companies, specializing in the design and manufacture of mobile accessories, launches a USB-C-only power bank on Kickstarter. Named the PowerPack Ambi, it can deliver up to 18W output and input for faster charging and recharging.

As for the reason to go USB-C only, the team claims:

Our decision to go with USB-C only is based on our vision of a future where USB-C is the only port on all your mobile devices. This is a vision that is shared by major device manufacturers like Apple and Google. We want the PowerPack Ambi to be a portable charger for the future and not stuck in the past.

Also, according to ZMI, If they implemented other protocols like Quick Charge in addition to USB PD, that would violate the USB specification by the USB-IF organization.

Main features:

Includes a 50cm USB-C to USB-C cable

One of the smallest dual USB-C port power bank

No legacy ports, only USB-C

Previously Mi Power Banks was a great success being the most sold power banks in the world with their stylish design and high quality. We’ll wait and see whether the PowerPack Ambi is another successful evolution of the legacy.
