  • USB-C cable shopping for an iPad or Thunderbolt 3 Mac is still a nightmare for consumers

    Thanks for this article that made me realise not all cables are the same. Unfortunately, I’m more confused than ever.

    I was hoping that someone could help me choose the right charger and cable for my new 2018 3 gen 12.9” iPad Pro.

    Apple’s support article: https://support.apple.com/en-us/HT209186 rather unhelpfully advises: “If you have a higher-wattage USB-C power adapter — such as the one that came with your Mac notebook — you can use it with iPad Pro, and you might see faster charging.”

    On the ATP podcast, Marco Arment says he was told that the maximum charge power the new iPad Pro can draw is 45W. The 18W adapter that ships with the product says it outputs 5V, 3A or 9V, 2A (hence the 9 x 2 = 18W).  

    So, I think I need to buy a full PD spec cable (100W, 20V), but how do I choose which PD charger to buy? What maximum voltage and current will the iPad Pro’s port draw? There seems little point in spending extra money on a charger with power that the iPad can’t exploit.

    Thanks in advance for any response. I realise that my questions may demonstrate a lack of electrical understanding, but I think it is more because Apple don’t publish the full specs of that iPad’s port.
