    Has anyone tried if iPhone 8 fast charging works using a standard Macbook USB-C power supply and USB-C power cable together with a USB-C -> Lightning adapter like this one:

    I'd prefer to just take a small adapter when traveling instead of yet another cable (not to mention that the price of Apple's USB-C/Lightning cable is ridiculous).

    It will not charge at maximum rate capable if you used a direct lightning to usb-c cable, but in practice it may not matter. Early testing is showing that the new 'fast' charging is not a whole lot faster than people were getting using an iPad charger previously - ie. about 40% in half an hour on the plus models. I guess the regular 8 model may charge a bit faster, but you won't get full speed without the right cable.

    Thanks. But has anyone actually tried charging from the Macbook charger with one of those adapters? The same speed as with the iPad charger would be fine (faster is of course better, e.g. to recharge at an airport). I usually don't bring my iPad and its charger when I already have the Macbook with me. Being able to charge everything from one charger would be nice.

    When 29w fast charging first became a possibility on the 2015 iPad Pro, no adapters or other cables would enable it. Then, as now, only the Apple cable will do.

    Does 29w vs 61w make a difference? Like is the fast charging capped at 29w anyways making the extra power pointless?

    I have a 29w with Apple USB-C to Lightning cable. It does the “I got plugged in” beep twice, once on connecting and a few seconds later when it realizes it can fast charge. Beyond that, it’s noticeably faster than my iPad charger, but not “worth the money” faster. Note that my comparison is a half-dead 6+, so my data may be skewed.

    Did the phone get warmer than normal than when using an iPad charger? I heard on a review and test it got warm with fast charging.

    Can’t you use the MacBook Pro charger cube with a usb c —> lightning cable to get the rapid charge? Not sure why you said it wouldn’t work. It’ll just be capped at 29W

    It gets warm, but not scary hot. I have a Rhinotech Playproof, so it’s pretty thin. It is warmer than charging off a normal iPad charger.

    I said using the posted adapter it's not going to work - the cable is a very important element of getting the fast charge and some cheap knockoff in the chain isn't likely to reach the full charging potential.
