I have multiple micto usb charging cables from Verizon both home and car chargers. I have been using the home charger that says 5.1 output all week and it seemed to be working. Last night my battery was near 0 before putting on charger. In the morning or had no charge still. I plugged the cable in and out and it said use an LG cable. I tried the LG cable marked 5.0 output and it worked and a Verizon cable marked 5.0 output also worked. I am not sure what output my Verizon car charger is but I will test next. Does LG make a car charger?
