As for the Chademo adapter... I never regretted spending the money on it. Have used it many times and it is great for peace of mind knowing that anywhere there are chargers, always have access to the fastest ones there are. Last week waiting for my wife at Pearson Airport in the cell phone lot and charging at the Chademo there. Her flight was delayed for 50 minutes, so got 24.9 kw while waiting. Sweet.
