My does my iphone charger keep breaking when I plug it into the laptop?

Last year I'd gone through about 5 chargers. I found that it was usually after I plugged it into the Dell laptop that I have it stopped working. Not always but eventually. It used to come up with a alert saying Port Hub has exceeded or something, and the charger end part smelt a bit burnt and it stopped working.

The latest charger I got I decided not to plug it into my laptop for anything and It has been lasting Way longer than any of my previous ones.

I like to plug it in my laptop to put songs and take photos out of it.

What's the problem?

Probably you…
