Why do you say that? Do you mean if you are using the Rivian EVSE or are you commenting on the CPH50 at their advertised rate with 70/80amp feeding a full 50 amp constant load?
Rivian caps out at 48A (11.5 kWh) charging, which Rivian has said will provide approximately 25 miles range per hour.

Because different EVs consumer a different number of Watts per mile, you can't say that a specific charger gives "47 miles range" to any EV -- you must specify which EV you're talking about. Since this is a Rivian forum, using a Rivian vehicle would be most relevant. If you use a 48A+ EVSE then you're going to cap out at ~25 miles range, per hour. Even if you have a more powerful EVSE, you'll never charge faster than that (Level 2). At 32A it's ~16 miles range, per hour.

99% (guesstimate) of all L2 EVSEs that "plug in" use NEMA 14-50.
Agreed, however understand the NEMA 14-50 is meant only for 50A maximum—not a continuous load as required in EV charging. Hence, if you go that route instead of a hardwire, you are limited to setting your EVSE to a 40A max load (80%) on a 50A breaker, which will increase one's charging times. This may, or may not, work depending on individual needs, particularly in light of the ~25-mile limit at 48A as posted above. Those extra 8A may be handy to say nothing about “future proofing” the circuit for multiple/future vehicles...
