My Samsung fast charging wireless unit quit working.

[AC Question]

The cord it is plugged in with is good. When I unplug and plug back in it flashes blue, green and then blue about 5 or 6 times and then goes off. It doesn't seem to be paused or sleeping.

Try different power outlet(s) and see if that helps. If not, then I would suggest contacting Samsung as the device may be defective.

Have you tried re-positioning the device? Some wireless chargers require precise positioning in order to affect a charge.
