Hello Forum,
i am searching for a Powerbank (in Europe!!!) to Power the Octatrack MK2 via a Ripcord converter cable.
I have no acces to the Bonai Powerbank which is reported as a working one.
The ones i tried all fail to deliver the right amount of Amperes at the USB Port.
So:
who knows, and uses one - available within Europe - that will do the Job.
Thank you for all Infos 
Cheers
