Android device and Apple device actually are different in charging point. The USB high speed data line (D+/D-) are opposite in these 2 system. That’s why some chargers can only support one of these, or some charger make 2 USB ports, one USB indicate for android device, one USB indicate for Apple device. That makes consumers confused. With the smart IC, the USB charging can detect the device D+/D- status can switch automatically. You don’t need to check if the USB port is suitable for your device or not, just plug and charge.

Some chargers make low current like 1A so you will find it charge your iPad too slow, some chargers make high current like 2.4A but you might find your device battery is becoming worse and worse, ruined by the charger. With the Smart IC, the USB charging can detect the current your device needed and offer the correct current, neither charging your device slow nor ruining your device.

At the beginning, only Texas Instruments can make this smart IC, so everyone use TI only. But the unit cost of the IC is quite high for the products. That’s why you will see the price of products with smart IC is quite high at the beginning. Later some other Taiwan IC companies also offer such kind of IC, and make the market price lower.

Many brands create one series brand name for this Smart IC, but basically they are same. Like Power IQ for Anker, iSmart for Ravpower, chargewise for IXCC, etc.
