difference
Basically no the same place ~~ The so-called mobile phone direct charge is actually a power supply, charging management in the mobile phone and the charger is not the same, the quality of the battery charge depends entirely on the accuracy of the charger, the charger on the market is very garbage, only the official charger of the mobile phone manufacturer is better, the brand is slightly better. Just can only use it ~~ Now want to buy a suitable but charged, not undercharged charger is difficult, basically rely on DIY
