Nearly every airplane these days has 5V USB power port at every seat. Some of these appear to be configured for power only, while others appear to be configured for both power and data transfer, since I will sometimes get a prompt on my iPhone: "Allow this device to access photos and videos?"
I think on some planes it might be possible to play media from your device on the seatback screen, but I'm not sure since I've never done it.
Is there any risk to using these USB ports if a malicious person is connected to another port on the plane? And is the risk any different if you allow/disallow media access?
please add appropriate tags, unsure which ones to use
