    Ok, so maybe you haven't heard, but the expensive new MacBook Pro has an USB-C port. I know, not something people talk about, right? Anyway - you can charge it with a lot of things now. External batteries, 3rd party chargers, monitors, tosters, etc.

    My question is - is it.... safe to use those various power sources? The only chargers I ever used with my Apple devices were the ones I got in the box. In fact, I don't even like to charge my iPhone with my iPad Pro charger.

    Now I know the tech that regulates the voltage (or whatever it is) is inside the device, not the charger. But still, I'm kind of scared to experiment. And I'm not talking about using cheap fake chargers either - I would be scared to take an USB-C lightning cable and attaching my iPhone to my 87W MacBook Pro charger. Would that work? Would it be safe?

    With iPhone 6S battery recalls, Note7s exploding and everyone trying to charge batteries as fast as possible - I'm a bit reluctant to attach my MBP to something that isn't the Apple MBP 87W charger.

    My question is: should I be worried? Can I safely use external batteries, 3rd party chargers, different Apple chargers, etc. Anything I should know?

    Thanks

    I'd be wary of any device not certified by USB-IF. You're safe otherwise.

    As far as 3rd party power banks, you should make sure it's certified; chances are it most likely won't charge at the rate that the 87W charger does, so the main purpose of the power banks is to extend your MacBooks battery life (unless you charge it while it's sleeping).

    As for different Apple chargers, the charger itself will change the output for the respective device. So the same 87W charger can charge the MacBook at 20.2V---4.3A and an iPhone 7 at 5.2V---2.4A.
