Smartphones typically have a restricted output current for OTG devices. Furthermore, smartphones yield a lot of internal interference, so powering from them isn’t the most ideal.
With the CB19, dongles can power from a clean source, such as a power bank, instead of your smartphone. Your DAC dongle gets quality power with minimal interference with the CB19 while simultaneously preserving the battery on your smartphone, achieving optimal performance from both your phone and the dongle.
I use this cable to connect my Cayin RU7 to my IPhone 16 Pro and an external power bank. It works perfectly.
Bought this so that my DCA Noire X + Ibasso Nunchaku wouldn't suck my phone battery dry. It works perfectly. Looks great. Solid build. No complaints, highly recommended.
Thanks Bloom Audio for another great experience!
Wish this came in the box but works as intended, I can now charge and listen at the same time!
Made dc elite sound better
