El Al Matmid - In-seat power on 747?

I've tried searching. Seatguru says the 747s have no power ports,
but this (http://www.executivetravelmagazine.com/page/El+Al+upgrades+747-400s) contradicts it. So I turn to you for the truth.

On an LY 747 between JFK and TLV, do the seats have power ports,
and if so what kind? I'm interested in the answer for economy and
business class. Thanks.

Only in business and it's a standard plug connector - you can connect a US power supply.
