3 USB-C to iMac
- Amount Charged in 30 Minutes: 34%
- Total Time to Charge: 1 hour, 45 minutes
- Cost: $25
Onto the methods that will cost most users extra money. Forking over $25 for a USB-C to Lightning Cable will allow for a noticeably shorter charging time when plugged into an iMac’s USB-C port. The iPhone 8 hit 34 percent in testing after 30 minutes, and reached 97 percent after 1 hour and 45 minutes of charging. Presumably, it was fully charged just a few minutes after.
