My charger has been fine until recently although I noticed it getting warmer. Last night it wouldn't charge at all and this morning it was so hot I could just about touch it with bare hands. I couldnt get the iPad to start up and eventually noticed a message "only use Apple charging devices as others may cause harm" it was then that I began to use my MacBook Pro USB.
The iPad charges okay from my MacBook Pro USB, is this a common occurrence? I bought the iPad as a manufacturers refurbished and has been fine in every other way.
