    Just got my iPad 12.9-inch Pro

    Decided not to use the included USB-C charging power brick.

    Reason being, I have a really nice braided Anker 6' USB-C to USB-A cord.

    So I am using the older 12W charging bricks that came with prior iPad Pro models.

    My new iPad pro seems to charge much slower. Additionally, when using the iPad while plugged into the charger, it loses charge rather than keep it.

    Is there any difference in the rated power of the prior 12W chargers and the new USB-C chargers included with the new iPad Pro?

    The charger that comes with the 11” is 18W.

    I’m interested in finding out whether there’s a difference between the included 18w and the Apple 29(30)w? The difference wasn’t that huge between the 12w and the 29w when charging an iPhone so I doubt there is.
