-----Digital device charging common sense science----

   Charging current is determined by three factors: 1. the charger output capacity; 2. charging line of transmission capacity; 3. mobile phones or digital device's ability to receive current. During charging， the actual current size with all the above factors are closely related. The cord just solves the 2nd item， provide a good pathway for charging. The actual charging current， or charging rate also needs to look at the 1th and the 3rd.

   Take a simple example， pump cord is like home， you buy a thick pipe， but the actual outlet size depends on how much water companies give you water， and how big your tap. You turn the tap off so small， small water naturally， water companies give you a small amount of water， water is naturally small， or even water， a drop of water or， to walk on water at mealtimes. Water company here is the charger， taps is charged for digital equipment.

   Do not know if you understand yet?Therefore， if you decide to buy 2 a line， we will be able to fill current of 2 a phone， flying generally charge， that thinking is wrong!

Important notice:

  As with data capabilities， D+，D-is not shorted together.If you charge head D+，D-not togetherSome Android phones not charging or charging may occur slowly， if you would like further information please Baidu "Android handset identification resistors."
