The inlet is for her to connect the strap on gear she's wearing into some smart cable so she can move around in the air with great flexibility. Though now that I think about it, the connection might not be strong enough to hold a cyborg in motion, but ... ... hmmm, cyber-wizard and futuro magic make it possible kehehe XD.
Her power plugin is on her left arm, enclosed with a piece of metal to protect from wear and tear.
Thank you sojuchan! You are too kind :D.
