What happens if I use an incompatible power adapter?

I've been looking forward to buy a macbook air that comes with a 67 W power adapter. I've read that the adapter is only compatible with mac devices. My question is, what would happen if I tried to use that adapter to charge an iPhone? Would it damage it or would it just charge it at a lower speed?

the iphone draw as much current as it was build to use when charging, the fact that

a charger can provide a lot more just means it's not having its full capacitive
