Using a non-apple iPad connector results in "no charging"
Hi, I have an iPad Air 2, and it had charged fine using an Apple usb transformer with a USB to lightning connector. However, recently I lost the USB-lightning connector, and had to use an separate one that I found around the house. When I connect my phone to a charger with it it warns me I am using a non-Apple product, and when I connect my iPad it says "not charging". Why won't my iPad charge with it?
