Query: Hit or miss. Don't use the car charger plug.

A word of caution, this is a low priced item because corners have been cut and the quality control isn't very good.I've purchased 5 or 6 of these items now and for the most part everything has been fine. I've never had an issue with the USB cord or the wall adapter but I've had a few problems with the car charger. A couple of the sets have refused to charge my phone. Which isn't to bad for something this cheap but recently we had something a little more concerning happen. I gave a set to my mother-in-law to use for her car. Before she realized what it was she had fried the fuses in two separate cars when trying to use the charger.So if you want a cheap USB cord and wall charger then this is a decent cheap set. Don't buy this for the car charger, its not worth damaging you car or device to save a couple bucks.
