I was doing pattern work (touch and goes) with one of my students and on our second lap while climbing out on the upwind we lost the power at 300ft ; wasn't a complete loss of power but the RPM dropped to 1000; the airport has a 2 parallel runways so I decided to turn towards the parallel runway because there wasn't enough power to climb out but while turning the airplane got it's power back again so I decided to keep going and just enter the crosswind for the parallel runway; I believe that there was something wrong with the carburetor that caused the problem; I didn't declare the emergency but I did asked for a priority but I think I should have declared the emergency because that will probably make everything clear to the tower and everyone but at the end of the day we were safe on the ground with no injuries or damage.
Piper PA28 flight instructor reported the engine lost power during climb; then regained power when turning crosswind for a parallel runway.
