Many people who purchased the new iPad tablet complain that they are unable to charge the battery of the tablet while using demanding applications or they play games.

The problems seem to appear when using the AC 10 W adapter included in the accessories package as well as when users are trying to use the USB 2.0 connection.

Not being able to use the USB 2.0 connection for charging can be understood easily if we consider the capacity of the battery, which is 70% bigger than the battery of the iPad 2 tablet.

Given the huge difference between the maximum energy absorbed by the charger and the extremely low voltage of the power provided by the USB 2.0 connection it’s natural for the charging time to be bigger.

As such, it’s easy to understand why some people are complaining that the new iPad gets discharged when it is connected to a USB 2.0 port.

Still, we can’t understand why Apple included only a 10 W Ac adapter in the package of the new iPad, considering that a MacBook Air with almost the same battery benefits from a four times better adapter.

Even if we plug the AC adapter the new iPad tablet gets discharged fast if we operate demanding tasks, like playing games or using multitasking. Ironically, in all this time the iPad tablet notifies us that the  battery is charging, even if, most of the times, things are exactly the opposite.

It seems that this time Apple engineers completely ignored the laws of Physics when they designed the new iPad, as these problems are also causing overheating problems and also the impossibility of charging the new iPad on the go, without closing opened apps.
