Battery-powered USB hub?

post #1 of 9
Thread Starter 

Does anyone know of a decent battery-powered USB hub which is currently available on Taobao or EBay?

 

Thank you.

Can you not use a portable battery to power a small hub?

I've tried a battery-powered USB charger (basically a battery with a built-in charger), and am having problems with clicking noises. Do you have any specific recommendations regarding battery PSUs (brand, availability?).

Clicking noises in what? You have not specified the use for the whole device, so it is hard to guess where the cllicks appear and recommend anything

When the D7 is powered via a powered hub connected to the USB charger (battery powered), and IEMs are connected directly to the D7's headphone socket, a regular ticking noise is heard in the background, regardless of the volume setting or of whether a source (iPad) is connected or not. The ticking disappears when the charger is replaced with a 5V "wall wart".

Battery might be poor quality. Try some other portable battery. I have a New Trent IMP70D, but have never used it for powering a DAC.
