Moisture Detected Message When Trying To Charge.

This might sound dumb, but have you tried a different cable or brick, or both?

As far as I know, the way devices detect moisture in their charging ports is through a bit of logic applied by the USB controller to each pin on the connector. Most water that a device would be exposed to has minerals in it which, long story short, is how water ends up ruining devices. How the logic works is basically: if pins 1 and 4 are supposed to have voltage when charging, the rest of the pins aren’t supposed to have voltage, and this is what the USB controller “sees” on the USB port then things are fine. However, if the controller detects that pin 2 has the same voltage as pins 1 and 4, then the controller raises the alarm and the device says “Moisture Detected”, resulting in what you’re currently experiencing.

As examples, if your USB cable has a bent pin or two and is providing charging voltage to pins that aren’t supposed to be used for charging, or has a short internally which is providing voltage to pins that shouldn’t get voltage, or if there is some internal fault in your charger that’s resulting in charging voltage to be sent to pins that aren’t supposed to get charging voltage, then the USB controller would “see” the same conditions that water in a USB port would cause, and raise alarm bells.

What’s potentially more concerning to me is that Apple won’t look at their own product because it’s not the “right country”… If it’s brand new, I would call Apple and sit on hold until someone can provide you a solid, legitimate reason as to why products from Apple Thailand are so vastly different and incompatible with the products sold by Apple Philippines, since Apple Philippines refused to touch your iPad.
