Ipad/iphone Connect computer show not in charge how to solve

First, it should be to make sure that your ipad is not a problem (because it's just unpacking, and you're more trusting of Apple's products.) , and then look at the ipad with its own charger charging voltage is "5.1V and 2.1A", while the ordinary PC-side USB interface output parameters are generally 5V and 500mhA, with the ipad to connect the PC display "not charging" It should be because the PC-side USB interface output voltage and output current are lower than the ipad's charging standards.

Summarize the solution

Method One:

With regard to the ipad Air charging on a common PC, there is only one extremely stringent implementation method, which is to install a program called "Ai Charger" on the computer, which allows the PC to support the IPad air charging, the principle of which is to modify the registry USB current settings.

Method Two:

Connecting the ipad Air through the data cable to the computer will display the word "not charging" in the upper-right corner of the ipad Air, because the Windows system does not have the appropriate hardware drivers installed, and the solution is simple: Download a hardware driver after installation is complete.

Method Three:

To understand the computer Tatsu people should know, ordinary computer USB interface output parameters are generally 5V and 500 Ma. Let's take a look at the charging voltage of the ipad's own charger, which turns out to be "5.1V and 2.1A".

When you see these two sets of numbers, you should know that the ipad is "not charging" when it connects to the PC because the PC-side USB interface outputs voltages and currents far below the ipad's charging standard.

Method Four:

When the ipad shows "no charge," is it charging?

In fact, when the ipad is connected to the PC via USB, it is also charging the process, but due to low voltage and current, charging speed is extremely slow. In general, charging the ipad with the ipad's original charger will take about 2 hours to connect to the PC in this low voltage current situation, and it takes 10 hours or more to fully charge the ipad.

The exception is that Apple's all-in-one and laptop can be used to recharge the ipad because their output voltage is up to the ipad's charging standard.

Experience

I'm using an Apple phone and I'm not charging when I connect the iphone to my computer. But I will find that there is a problem if we connect the computer after the installation of a driver box, if we turn off the driver to install the box does not show the charge, if you protect this state is no problem.
