How to power a device connected to an iPad?

[d-b]

I am gonna connect a RIAA pre amp to an iPad to transfer audio from the amp to the iPad (via Apple's Lightning to USB 3 Camera Adapter). This amp is powered through USB (requires only 0,1 A). Would the iPad be able power this amp? If not, how do I do that?

No,it won't. iPads cannot power anything.

Except for an Apple Smart Keyboard, or to charge an Apple Pencil, or...
