Anyone who has used an iPad knows that using the USB interface of a computer or laptop can't charge the iPad at hand. The reason is that iPad charging requires 5.1V voltage and 2.1A current, while the USB interface provided by the computer can provide 5V voltage and 500mA current. The difference in current parameters makes it difficult for ordinary computer USB to meet the charging needs of the iPad. Therefore, when users connect the iPad with the computer, the iPad will display "not charging".

In fact, when the computer is used to connect the iPad, the iPad is not "not charging", but charging the iPad with a slow current. The whole process is relatively long, and it may take dozens of hours to fully charge the iPad. If you continue to use the iPad during the charging process, the more you charge, the less power you will have. This problem is a headache. Do you want people to take the charger everywhere every day? Is there any way for the computer to charge the iPad normally?

Annoying "not charging"

Yes, of course. To solve this problem, just increase the output current value of the USB interface. In response to this problem, ASUS launched a software called Ai Charger, which was originally launched for ASUS motherboards, but can actually be used on most motherboards at present. The principle of Ai Charger is to modify the USB current related settings in the registry to meet the needs of charging devices. Ai Charger enables desktop PCs and laptops to charge iPads, whether at home or out, at work or for entertainment. Officially, Ai Charger can increase the charging speed of iPad, iPhone and iPod by up to 50%.

The operation method is also very simple. Download and install Ai Charger（ ）, you need to restart it once after installation. After restarting, you can see that an "Asus Ai Charger" icon similar to a charger will appear on the taskbar. At this time, connect the iPad to the USB interface of the computer, and the charging will start automatically. Of course, the display status of this icon is very intelligent. After connection, it is in the "Charging" status. When the device is not connected, it is in the "Disconnected" status.

How about the test results? The author used the iPad 4 to test, and the battery was fully charged from 30% to 40%, which took just 50 minutes in total. That is to say, it takes about eight or nine hours from low battery to fully charged, which is much faster than the slow charging of ordinary computers for at least ten hours. Compared with using the original charger for seven or eight hours, it will not be too slow, so the charging effect after using the plug-in is still very good.

In addition, some readers may worry that after installing the Ai Charger software, will the current value of the USB interface become larger, causing harm to devices such as mobile phones with low current requirements? The author tested the use of other products and found that Ai Charger can only recognize Apple's iPod, iPhone and iPad devices, but not Android or mobile phones and tablets. In this way, there is basically no need to worry about software damage to other devices. In addition, after testing, the USB flash disk can also be used normally without being burned out. If you need it, you can use it with confidence.
