anyway is there any battery overcharge protection? intend to leave it overnight charging while i sleep
It is using lithium polymer battery and by theory it is safe to charge overnight. The most it will get bloated if something happen , won't explode.
While charging battery, you may find it a bit warm but when battery full, you noticed that DreamPad II is cooling not warm at all. It is because the mainboard stop excess charge from going in.
However precaution is better than cure.
For some reasons, even iphone does explode,

So what goes wrong? Same theory as milk power incident in china, to cut cost and result in tragedy. Maybe the factory was squeeze to dry dry then find way to cut cost lor...
Many pple assume battery is the culprit but come again, before this excess power goes to the battery, where does it goes to first? This is just assumption if base on what i study in school for electronics. Just theory.
So conclusion, precaution is better than cure. This same applies to all products around our daily life, be it branded or non branded.
And remind me of something, wifi in our home does cause radiation but to certain extend but we still on right? some even sleep beside the modem xP ..ops.....
