I’ve had my Ioniq5 for almost 2 years and finally did my first longish trip. NYC area to Boston and immediately back. First time relying on DC fast charging and at first was kind of nervous but I can say it was flawless. Went thru two Electrify America stops and got high charge rates both times. Experiences no lines or charging issues at all. Also was free. Will not hesitate to do it again.
The whole East coast Interstate system (mainly I-95) is pretty good. North of Augusta, ME can get a bit interesting, but Boston to Orlando is a piece of cake.
