So I have 2 USB cords for my Warp but one has become wore out I guess because its loose when I try to charge. I like to have one for my car and one for the house. Do they have a specific size number or something I can look for online to replace my bad one? And where is the best place someone would recomend to purchase it. Its not the port on the phone its the small end of the USB that seems to be wore out/lost its tight connection. Thanks.
