I don't know, measurement wise, how much it makes. On a normal day the ice maker dispenses enough ice for our family of 5. (However I myself do not use ice frequently, so maybe it'd be more appropriate to say family of 4). On a really HOT day, all of us were using more ice than normal and I noticed our bin was running low. I turned on the acceler-ice feature and we never actually ran out. According to the manual it increases ice production for 24 hours. I couldn't find any details on this except that description, but it seemed to work for us. If we ever plan any parties, I plan to turn the feature on the day before and make sure to re-set it during the party.
