[QUOTE="RadDave, post: 1629728, member: 234411"] Well, your new iMac has USB 3 ports which provide nearly 5 W of power - see comparison below ([URL="http://support.apple.com/en-us/HT4049"]SOURCE[/URL]) - not sure which model phone you own (and there will be a difference), but I just bought my wife an iPhone 6 which came w/ a 5 W charger, however, I have her plug it into a 10 W charger (like for the iPad) for a much quicker charge. Bottom line, your phone should charge faster on your new computers USB 3 ports, but for the fastest charge, depending on which iPhone you own, an iPad or comparable 10 W AC charger will be the quickest way. Dave :) P.S. If you do not know, Wattage = Amperage x Voltage. [/QUOTE]
