Dc 3V Micro Mini Mute Air Pump Oxygen Pump M20 Motor Pump For Fish Water Tank Sphygmomanometer Monitor

Compact. shakes normally. It makes noise like a quadcopter. An excellent option in case of power outage. Works both from 3 Volt batteries and from a power bank of 5 volts.

Very noisy. One of the two pumps is used and the other is new. They work normally, if on a reduced voltage, then they do not make much noise.
