I have 3 powerbanks. from 10.000 to 20.000 capacity.
I use it with a 5v usb to 12v Socket power converter cable-adapter i bought from amazon.
Not the Ripcord
The only one where the DT2 works with is one from Intenso with 10.000 and 3.1A output.
It works like a charm and i get around 2-3 good hours out of it.
Is it safe to assume that it needs >3A or is it my Voltage converter?
Who has the Ripcord and what specs of a Powerbank works for you?
Check towards the bottom (the more recent responses), that’s where the discussion turns to DTII specifically although there will be other relevant information throughout.
I might search the topic for your ripcord using “ripcord” as a keyword. When you click the magnifying glass while you’re already inside of a thread there’s a check box which says “search this topic”, you have to click it to get isolated results out of the search engine.
