Review on 🔧 Koto 12V DC Air Compressor Pump - Efficient Tire Inflator for Versatile Applications by Chris Burns

This pump has a low average sound. Other air pumps have a high pitched sound. A shrill sound wakes the neighbors. The pump is fast. but you should pump 3-4 psi higher than your desired psi range since 2-3 psi will be lost when you loosen the valve. This pump replaces the failed green mud air pump. he was sucking air instead of giving air. I hope this pump lasts a long time.
