The biggest issue is that people still recommend usb drives. Do not use USB drives! Buy microSD cards + USB adapters instead. They don't need much power to operate and they don't get insanely hot unlike USB drives, plus their reading times are top. I have several microSD cards with their own adapters.

Also, I recommend going the OTG route, which means you would have to install bleemsync first..
