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

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?).

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".
