That seems like something that could be solved by color coding or otherwise marking the connectors. I know Apple is allergic to color coding (and colors, generally), but there's opportunity to expose more information to the user other than simply by the physical shape of the connector itself. IMO, the connector should prevent you from doing something dangerous and/or harmful (i.e. you mustn't be able to plug an unregulated charger into a device that's going to turn into a flaming ball of slag) but the fact that a device is going to charge slowly is sort of a "SHOULD" rather than "MUST". Marking the connectors -- put a different symbol or color on high-current ones -- would go a long way towards alleviating the unpleasant surprise of not having a device charge like you expect it to. And while I know that designers and developers like to laugh at the stupidity of non-technical users, I don't think the average person is incapable of discerning that (say) "hotter" colors mean more available charging capacity, provided that it was standardized. Hell, they're probably fine actually reading numbers as well, if the number of amps of available current was clearly marked in the same place on various chargers and not in minuscule print.
