It’s a shame that Apple iPods, iPhones, and iPads with USB Ports do not exist. You’re not out of luck. Although Apple doesn’t include them, it does not mean that you cannot use one. You simply need a Lightning to USB port adapter or a docking station.
Currently, all of the adapters available provide a micro USB port. To get to a full-sized USB port, you would just connect an OTG cable. Now that you know that you need two different adapters, you may be thinking it’s expensive. It’s not; you may be looking at less than $15.00 for a full-size port considering the cost of the adapter and OTG cable.
