Suspect he's talking about part 6627 which is in the 2018 price list - I didn't recall noticing this before but it's not marked as new. It is what it says on the tin AFAICS, ie a 5v supply cable for console etc but with a (full-size I think) USB connector on the other end for connecting to eg a smartphone charger.
Incidentally, there's also 6670 as a new part which is a pole-mounting bracket for a single solar/UV sensor.
