Some devices don't like being connected to a high-amp charger. My Blackberry will charge from a Kindle Fire charger, but it won't accept a charge from either the USB charger for my wife's iPad or the USB charger for my Galaxy Tab 7.0 Plus.

My Kindle Keyboard isn't picky at all. It charges from any charger.
