Fast chargers communicate with the devices they're charging, to see what the device needs. (Send 9 Volts or 12 Volts to a device that needs 5 Volts and you can blow it, but send that to a device that uses 9 Volts or 12 volts for faster charging and it charges faster.) It sounds like a communications failure, to the point that the charger can't tell what the Samsung tablet is, so it doesn't send anything to it. Parts do fail - if he's sending you a new one, and it works, chalk it up to "meet the real world".
