Looking at some of the chargers out there and it seems like the specs and power delivered by a "portable" charger is pretty much the same as wall mounted units. The one big difference is the price with potable models under $500 and wall mounted units over $500. This isn't an exhaustive search result, but I found what seems to be a decent portable charger (Mustart) for $350 and a wall unit (JuiceBox) for $600 on Amazon. I've read a thread on this forum that seemed to show both styles in use by I-Pace owners. What are the pluses and minuses for each in a typical garage setup indoors? I figure I'll have a portable charger in the car, but not sure why that isn't just as good in the garage. Thoughts?
