What is the proper way to charge an iPad Pro 3rd Gen 12.9 in a car? I want to know exact watt, Amp requirements. I don't want to just wing it...
iPad Pro 12.9-inch, 3rd Gen, Wi-Fi, Cell
Use this from Apple Belkin USB-C Car Charger - Apple
There's not much you can do to effect the watt output of either a USB Charge port or the cigarette lighter port in your car. So don't worry about the output, it won't hurt your iPad at all. What you will need is a USB C to USB adapter, because no car that I'm aware of currently includes a USB C charging port.
Something like this should fit the bill: https://www.amazon.com/Nekteck-Certified-Charger-Delivery-Included/dp/B075WQQG7C/ref=sr_1_1_sspa?ie=UTF8&qid=1547401132&sr=8-1-spons&keywords=usb+c+car+charger+quick+charge+3.0&psc=1
