[QUOTE="PGB1, post: 1949811, member: 76746"] If it is helpful, I have a MacBook Pro that is a senior citizen. It uses the "L" mag safe connector. I have one 60 watt power adapter and one 85. Testing shows that both take the same amount of time to charge from 10% to 100%. (+/-[I] ca.[/I] 3 minutes) How Tested: Sent battery to 10%, turned off apps & turned screen brightness low. Timed charge to 100%. Repeated twice on each power adapter. The computer must limit how much current is "shoved" into the battery, possibly to protect it. Keep in mind that that computer is a 2007 A1226 MAcBook Pro. A newer one possibly will be able to take advantage of the higher wattage charger. Maybe try both on yours and return one charger if there is no difference in charge time. Or, check the advertising for the computer when it was new. Perhaps it shows a choice of power adapters. I would assume the highest one to pick will be the highest one you would want. (On some of the new ones, there is a choice in wattage. Don't know about the older ones.) Paul [/QUOTE]
