What happens if the wrong cable/adapter are combined? I'm just curious as a non-Apple user. I mix-and-match USB-B chargers and cables between my various devices all the time, and never experience a problem (except maybe slower than maximum charging sometimes). I assume the issue here would also simply be sub-optimal charging; but I have heard that some USB-C situations can actually be dangerous to the device since more power logic is in the USB cable ends?
- saurik 10y agoI am pretty sure you can use the cables that are designed to support the higher wattage chargers on the smaller devices (and that's what I'm doing right now: Apple doesn't even sell the crappier cable the 12" MacBook shipped with a year and a half ago standalone right now, AFAIK).
- colechristensen 10y agoSome usb-c cables that don't follow the usb spec can be dangerous (i.e. cheap 3rd party cables) Apple cables wouldn't have a problem with this, they would just charge devices slowly. The only danger occurs when usb cables lie about what they can do (in the physical layer to the host/slave devices)
- bravo22 10y agocables are rated for different power and that is signalled by specific resistor values. I'm assuming in this case Apple just cheaped out, to save a few cents, and didn't make them all rated for 3A. Therefore you'd only get slow charging as a side-effect.
