    i love how fast the 29W USB C charger charges my iPad Pro 12.9 inch. I want to get the same performance at work without having to pay $70 more for the convenience of having two chargers.

    I bought a third party USB C 29W charger and a USB-c to lightning wire. Is there an app in the App Store that can compare if these third party accessories are charging my iPad as fast as Apple's official USB C charger? Or am I just going to have to compare them the old fashion way and time how long it takes to charge the iPad from a drained battery?

    if the charge on the iPad is 40% or less a fast charge should charge at roughly 1% a minute. so if you discharge the iPad to 10% in 30 minutes you should be at 40%. You can probably check it in 10mins and if you are at 20% you are good. Pretty quick. Or use an AC Power Meter. I don't think there is an App yet for the iPad to report what you are asking. Note though although 3rd-Party adapters have been found that work, currently I don't know that any 3rd-Party cables have been found. A cable adapter may work, waiting for the iPad to need charging to test one.

    This was an unanswered thread from last year. There are several threads in this and the iPad Accessories section about fast charging 2015's 12.9-inch and both of this year's iPPs.
