wait a second!! who says the EVSE upgrade only does 4.8 KW? pretty sure mine is programmable up to 25 amps or 6 KW? and yes that would require a 40 amp circuit but you could also set it for 24 amps (5.76 KW) and a 30 amp circuit would work just fine.
I think the portability, price and adjustability of the EVSE upgrade makes this a no brainer decision
as far as speed, mine is only set to 4.8 KW but ONLY because I am using the worst breaker panel in use (been banned for over 15 years) today. Because of that, I chose not to push the limits and I have been fine. Just a few hours is all I need to get a significant boost in range. more than a few times, I have had tight turnaround times and have yet to come up short
