This USB3 vs USB2 or the port type (USB C) debate is irrelevant.
If the tablet USB port can only deliver 300 mA or less things are going to become tight on a 2 ch interface w. mics.
A typical mic requires about 2 to 10 mA from phantom at 48V, that's roughly 1/2 Watt maximum, possibly less.
The real question is whether the tablet USB port will give you at least 400 mA in which case there should be more than enough power available for a 2ch USB powered interface incl. mics.
