Now in a Vodafone store in Canberra, Australia an iPad exploded, sending out burst of flames from the charging port. A Vodafone person suggests that the cause of the explosion was as a result of extreme heat, in other words, the iPad was charge for too long. The firemen were called to put out the fire and no one was injured.
The iPad uses Lithium polymer and tends to explode when overcharge. And moreover, other devices that come with Lithium polymer batteries are no exception. That's why they come with the protection circuit.
An Apple employee went to the Vodafone office to pick up the device for proper investigation.
