Cathay Pacific Asia Miles - Older Equipment and Powerports

A quick question for the professional out here. During the last Cathay flight my FIL took last week between HKG-YVR-NYC he was told that Empower was not available but they had an older 7-pin power outlet.

Any ideas as to what this might be and where I can get one?

Hi
why would you want one
CX carries Targus units on board If Targus does not have it do not bother to buy it or it will be redundant

If it was the old DIN connector, it may have been the old IFE controller... and not even related to power
