I am pretty sure you can only take advantage of fast charging with the 10-core or higher (not the base 8-core). Also the 96W is fair amount larger, for what it’s worth.
Only the 96W can do fast charging… but it’s supposed to be bigger and less portable…
I actually changed my order because the 96W charger accelerated delivery by a week…
But I am wondering as well if there are any downsides to the 96W charger…
I am a little afraid that the battery might not like it very much…
