MFI Lightning cable Wholesale – The Lightning cable that iPhones, iPods and iPads have been using since 2012 is a proprietary connector created by Apple. Inside each lightning connector is a tiny authentication chip that tells your device it’s Apple MFI Certified. This is important because non-certified, or knock-off, lightning cables can be very dangerous to your device.These cables can often times get extremely hot, cause damage to your phone, and even render it completely fried and useless.
