Lot of 25+ smart Micro USB Chargers

These are smart chargers. They light up and show the flow of electricity as it charges. If a lot of electricity is going through the charger to the device the lights stream rapidly. If your device is almost charged or halfway charged the lights will move slowly through the cord and when your device is finished charging, the lights in the cord will turn off completely stopping the flow of electricity. Ithink they all light up in the color blue but there could be more colors. There’s atleast 15+ 3 feet long (These retail at $25 a piece)
