Car USB interface can not be resolved for the device to charge, the key depends on the car charger

With more and more people with the mobile phone, mobile phone screen has also increased a lot, the attendant trouble is that the larger the phone screen, the more power the phone. Sitting in the car when your phone is out of power, you can only stare, sleep and sleep, want to play the phone and no electricity. What should we do at this time? Everything is artificial, of course, there is a solution. Have a product called car charger can be very good, sitting in the car staring.

Here may be the owner said, my car with USB interface can charge the mobile phone, but you know, most of the car USB interface is ready for the transmission of data and the current is only about 500mA, when you use the mobile phone navigation charge capacity of the electricity consumed is not you. The battery capacity of iPhone4S 1430mAh, for example, 1A current charging just 2 hours or so can be filled, the use of the car comes with USB interface time doubled. So one can provide 1A or greater output current USB car charger is the best choice!
Some people may have doubts about the load capacity of the cigarette lighter interface, in fact, no need to worry. General car cigarette lighter fuse interface around 20A, some like MAGOTAN models such as 30A, even as some Japanese car design is "conservative" also has a 10A load capacity, and the vehicle power supply voltage is 12V, so the load ability of the cigarette lighter interface basically above the 100W car charger; to deal with the 5V output voltage of the power supply even if 4.1A dual interface is only 20.5W, so the load ability of the cigarette lighter interface is no need to worry about.
