Here is how to charge your iPhone from your MacBook Air battery. (It will work for a MacBook Pro as well.)
I was recently on a car trip and my iPhone went flat. I didn’t have a 12 V adapter to plug it into the cigarette lighter in the car.
I plugged the iPhone into the USB port on my laptop, but of course it didn’t charge because the laptop was asleep. I opened the laptop, and the laptop woke up, and the phone began to charge, but this was no good because it would have drained the battery of the laptop too quickly.
So I closed the laptop, putting it to sleep, and the phone continued to charge!
I estimate that you can fully charge your iPhone 3 to 4 times from a full MacBook Air battery.
Umm Hi i’m a student a UMKC and I’m about to take a test so umm yeah anyway i have a iPhone 6s and I’m trying to use my MacBook Air to charge my phone but it won’t continuously charge it and then if i close my laptop it will stop charging all together. So how do i just make it Charge my phone?
We’ve had the same problem while travelling in the car on holidays. The only way to charge our phone from the laptop was to keep the lid sightly open, which is a problem because then the mac heats up. There is an app called InsomniaX which will keep the MacBook awake with the lid closed, but this may overheat your computer. I don’t know of any way of keeping the USB port alive with the computer asleep.

I mean why doesn’t my MacBook Air have a USB?

if you face connecting disconnecting problem with your phone then follow these steps
1. Open terminal
2.and type ” sudo killall -STOP usbd ”
and if you want to charge your phone after closing the lid then follow these steps
1. Open terminal
2.and type ” sudo pmset -a disablesleep 1 ” ** it will keep alive your mac after closing the lid **
if you want to disable that mode then type ” sudo pmset -a disablesleep 0 “
