Newbie needs HELP!

Looking for suggestions for a quality budget friendly powered usb hub to be used between  my iPhone 7 (using Apple camera C usb cable) & my Peachtree Dac Itx (using its usb input). The dac needs power so I’ve been using the Apple camera C charging port but suppose a separate powered USB hub would be preferable; but don’t know if that’s actually true Any help would be very appropriated. Thx 
Oh yes. I believe you are correct Sir & that item should do the trick. Really appreciate your input & help. Thx very much. Cheers, Mike
@courant. One thing I truly hope I’m just not seeing- how can I use that power bank w my set-up ( iPhone 7 >Apple USB-C (camera adapter). USB-C output > dac usb input, & lightening charge cable>USB hub ( which now I’m using a standard plugged into AC outlet USB hub) without automatically charging my iPhone unnecessarily, and causing the dac to stop working? Thx for your help. Mike
You'll probably want to hunt down some form of USB Y Cable that splits power and data. Connect the power section to the hub as needed, and connect the data-only to the dac.

Beyond that, Google is your friend.

Hope that helps.
Absolutely helps. I’m just frankly amazed that this seemingly simple issue is this friggin complicated. Ha. Thx so much for your knowledgeable input. Cheers,  Mike
@mstrauss  You will benefit from using a 'reclocker' between your iPhone and your DAC. There are a number of options like the Sonore microRendu, Wyred4Sound Reclocker, SoTM, etc.

This will not only solve the problem you are trying to address, but also improve overall sound quality and musical performance. A true win - win with a small additional investment.

The 'reclockers' come with their own power supply, which can be upgraded to a linear power supply for even greater sound quality improvements. See how you like overall performance via the stock switch mode supply (wall wart) and decide accordingly. It is a worthwhile second future step. 

Whichever device you go with, check with Peachtree for compatibility (or the manufacturer of the reclocker).

Good luck.
