Unless my '13S is a unicorn, yes 27.5a on both 240v and 120v, I've done both
Note the reason Alozzy said 24a was not because that was the max but rather the max on a TT-30 plug. >30a at 120v isn't very common, to test mine I used a 50a plug(14-50) and just used the neutral and one hot, for testing.
A pre '13 Leaf charges a max of 16a @ 240v and worse yet only 12a @ 120v
Not sure if S model Leafs without the charge package also have the 12a 120v limit or if both voltages are capped at 16a, I've never had one to test and don't believe I've read how it behaves.
