This DC 3-5V Mini Air Pump is a low cost and used in Water Fish Tank Aquarium. The applicable voltage of this batch of air pumps is DC3V-5V, power-on test machine, the best working voltage is DC 4.2V, this time the air volume is good, the sound is quiet, of course the air volume at DC5V is more powerful, but the sound is a bit noisy.
The higher the voltage, the better the air volume, but the larger the current, the louder the sound. it works best at DC4.2V, the sound is soft and the air volume is also quite good. However, the air volume of the 130 air pump is a little bit different than that of the 370 air pump. It is much larger than the 031 air pump but less than the 370 air pump.
