If you posses an iPad and iPhone in the meantime, do you ever want to use 12A adapter of iPad to charge for your iPhone, will it charge quicker?
But sometime users do not attention that they can not charge their iPad if using charger of iPhone. Some users may noticed,if you opened your iPad while connected a iPhone adapter, it will consume your iPad battery soon.
It seems a little confused, but recently a video which used 2 iPhone 6s with 0 battery to compare. When you use iPad adapter to charge your iPhone,it’s quicker, but only at 5% about 13 minutes. Because one iPhone 6s was used the iPhone charger is 5W,another was 12W for iPad.
