THE # 1 CAUSE OF MICRO USB FAILURE IS MOVING THE CHARGING DEVISE TO MUCH PULLING/STRETCHING BOTH THE DEVISES PORT AND CHARGERS END. AUTO SPIRAL PIG TAIL CORDS BEING STRETCHED TO TALK WHILE CHARGING CAUSE 50+% OF ALL DEVISE PORT DAMAGE FROM PULLING. Put something tight into any hole and pull/push in every direction and that hole will not be as tight ever again.......... As a father of 7 My best advise to the person in the family who purchases the majority of the charging cords to make and make well known of a spot where "bad" cords go and firmly insist they don't get shoved under beds or thrown away. Every time a cord is needed you go to this spot and hope you have a few that don't work on opposite ends. I cut off the non working side and grab another cord that has that side still working and splice them together. I've found the standard usb end rarely is the problem and its usually the micro usb end that's the issue so my pile is usually most bad micro usb. It seams the auto cords fail more on the car side do to more parts in play so I usually have at least one. Also cut or otherwise damaged cords provide another source of good micro ends. If colors don't match search it online or trial and error. Don't make cords to long for power limitations to push it to far except in the car. I currently use a double length spiral pig tail type in car cutting the micro usb off one and cigarette lighter end off other leaving all cord possible and I can charge a phone in back seat from front seat. Last I found going out purchasing same exact cord then putting your broken one in its place then return or warranty the item now having receipt and package. Don't mistake that as me saying buy something put broken one in and return as if u bought a bad one but simply most have warranty for any reason and will replace it for free. Big box stores work well for this . Good luck and stop buying new cords get off your but and find one if the 50 in your house...
