Yes, unless you're using the newest and rarest non-superchargers, you're looking at 8-14kW vs 50-150kW. Also there are 3 or more different ones (so one app isn't enough) and because they take so long to charge people often park for extended (e.g. 4+ hours) periods. They border on useless, unless they happen to be where you work or live, if what you're looking for is a quick fill-up.
