I placed my Model X order without the secret 72 A charger option and I'm considering adding it to my order but I can't make up my mind (deadline: Saturday). Please help convince me one way or the other! Pros: - 50% faster charging speed where available. - It's only about 1% more cost to the order, so it seems almost silly not to get it. Cons: - Basically only useful with destination charging, and not even at every destination charging location. - Possible I might never make use of the feature at all.
