Definitely necessary product

For this purpose, the adapter is definitely necessary contradict other recessions. The Galaxy Tab uses only 500mA without adapter, with adapter probably about 2000mA.

If you put the tab with this adapter to the USB standard on the PC, the course has just an optical advantage, namely that the charging icon changes. Load faster not (although some USB controllers maybe be more current to flow ... and thereby be damaged?). Therefore, the adapter uses naturally only in a properly sized power source something!

Considering especially coming USB chargers for socket and car .. Without adapter useless for charging the Galaxy Tab.

I hope this recession Helps :-)
