As promised, Here's Bjørn Nyland's CHAdeMO adapter video.
What you'll see in the video is CHAdeMO charging a Tesla Model S (via adapter) versus Supercharging both a 60-kWh Model S and an 85-kWh Model S.
Despite its slower charging rate, Bjørn says that, without a doubt, he'd recommend that Model S owners buy the CHAdeMO adapter.
That adapter is only $495 in the U.S. and is being shipped out now to those who've been on the waitlist for quite awhile.
General ordering of the adapter will be available just as soon as Tesla fills the backlog.
