The pump stops and starts on its own. This happens several times a day
The general air pump itself will have an air bag, the pump will work into the air bag into the compressed air, when the pressure in the air bag reached a fixed value, will stop continuing to inflate, when the air pump will stop working. When the pressure of the package is not enough to support the use of the air pump, the pressure is automatically started. So it's normal to start and stop automatically.
Possible voltage instability or debris in it
