The G5 does not have a mirco USB power port. It is wider. What size USB cable is needed?
I think, like the G6 and V30, your phone has what's called a "USB-C" connector. Not a microUSB connector like the G4 had. Which is really quite nice!
Go to Amazon.Com and search for LG G5 USB cable. They are inexpensive to replace.
