I just got a new 15" macbook pro to replace my old macbook. I have a couple extra chargers for the macbook, and I'm wondering if it's safe to use them to power the pro.
Normally I wouldn't think it's safe, since the macbook's charger is 60W while the pro's is 85W. I'd worry it might damage the battery or not be able to fully power the laptop.
However, my dad has apparently been using an old macbook charger to charge the pro he got a few months ago, and claims it's been working fine.
I'd love to be able to use my old chargers so I can leave one at work instead of lugging around a charger in my bag every day. But I'm worried it might damage the battery's health, and since they're no longer replaceable I'd really like to avoid that.
