I have not used my Harumio one that I ordered in late May or June (going to go verify which one it is now). But living in Idaho, I am glad I have it for options. I just drove to Bozeman Montana and back and was able to do it via Tesla superchargers, but I could see absolutely do use ChargePoint or EA on some of these interior trips. Seems like ChargePoint is more common here. Some more chargers are going in in Idaho from the federal funds and that will open some options well. I could have fixed some range anxiety I had on the way back when I went through Dillon Montana, where apparently there is an alternate charge at a university campus, but made it to Lima Montana and the supercharger there by reducing my speed instead. My daughter is up in college in Bozeman and We will probably be making that trip. I prefer the way through West Yellowstone and Idaho Falls but my wife wants to go to Dillon and stop at the Patagonia outlet once in a while. So, will be useful there. Also, a CCS will be going in in Arco, ID, which will help when I don't to charge to 100% to get home from Lima to Hailey/Sun Valley.
So glad I have it. My trip so far have been serviced by Tesla superchargers but glad I will have this option especially for the price comparison.
Question, can you manually cause the car to precondition the battery for charging at one of the alternate chargers like it does when you navigate to a supercharger?
