“3 blue lights are lit and 4th one is blinking. This happens when the unit is plugged in or even if input power is removed. Since 3 lights are solid, the unit should have sufficient charge, but it does not charge any device connected to it. What's wrong?”

  Sorry, there was a problem. Please try again later.

• Make sure you hit the button on the top to start charging your device. If it’s still not working, try a different usb.
