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.

Super fast delivery and the cable works for exactly what i needed it for . To use a small power bank to power my Dac Dongle , now all my Dac dongles sound wayy better with better power then what my iphone can give ! More juice = higher quality sound and my phone battery dont drain ! Thanks Bloom Audio ! 2 day delivery and packed with care !
Nice build quality. I'm using the cable with an iBasso Nunchaku and a Nitecore NB Air.
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!
