You don't have to use EA. You can visit any DCFC station you please. SoCal is littered with DCFC stations from various providers but if you're like most owners, 80-95% of your miles will be from your garage outlet.1. Most important is cost of on-the-road charging. Unless Ford states and guarantees we will have charging rates (through EA I guess) of no more that $0.30 a kWh and no charge-by-time obviously, I am out. Period.
If all you do is long range driving though, the Mach-E might not be the best choice for you. Ford offers the Escape PHEV and Fusion Energi PHEV if you'd prefer.
