A:Answer Both USB ports on this device won't connect to an iPhone...just about every model. All expansion for an iPhone goes into the power connector port which is on the X, or the 8 appear to be USB C (which this has), but Apple's IOS doesn't allow external memory except for pictures. You can't add any USB memory and expand the memory of the phone and add movies, etc. like you can on an android (that's usually through SD cards), but they will recognize there is a storage device connected to the power port and read and write to them.
Even if you buy Apple's dongle to connect the power port to USB, it only allows pictures to be written and fetched from the USB device.
Generally the rule of thumb with iPhones is to get the model with the most memory on board if you want to store movies, or need the space, because except for pictures, you're not going to be able to use any device for extra storage (read/write) with an iPnone.
That's one of many reasons I moved to android.
