I just finished a 700 mile RT from Chicagoland to Eau Claire, Wisconsin this weekend. The way up didn't require a charge until I got to Eau Claire, the charger there had the bounce for a bit, but I charge from 8% to 75% in 1/2 hour while shopping. On the way back we stopped by a charger in Tomah and Madison and both seemed to give the amount of power expected at 50% charge, around 120 kW.
One thing I noticed is most dispensers had one cable out of order, but at least it was noted on the screen.
3.5 mi/kW average for the trip. The car was pretty packed with 4 adults and a full frunk/trunk.
