Extra pin
s. J1772 (aka Type1) supports one phase. Type 2 supports 3 phases.
Actually it is mostly missing
ONLY in US. Pretty much whole world uses 3 phases everywhere, incl Asia
US should also have it (as electricity is produced on 3 phases) but it is extremely rare as far as I understood.
Worldwide plug should be Type2. It supports everything while it doesn't actually have cons. The fact that diameter
is slightly bigger doesn't really matter, as there is no reason to have connector smaller than the handle (J1772).
Type2 supports lots of current in DC (as we already know from Tesla's non-US SC stations).
Type2 also supports regular 1 phase current.
And the weirdest PRO of them all: Combo 2, while looking extremely ugly, looks much better than Combo 1
