I lost the original charger on my Note 3 and my battery is completely drained. I've tried a bunch of other micro-usb chargers I have but the phone doesn't show any signs of charging. Even kept it plugged in for a few hours. The chargers work fine on an S3 and Note 2. I thought the phone was dead so I took it to a Bell store and they tried charging it with an original charger and it instantly showed the charging icon on the phone. They wanted $50 for it though, so I declined. Why don't these other chargers work? Some have outputs of 1 amp and others 1.2 amps.
