Testing Cheap Tools That Hit or Miss: Does This $39 Inflator Measure Up?
What happens here
The host moves on to test another one-star review from 'Brian,' which states that the 'PSI reading is way off, beware' and that the pressure reading is 'about 4-5 PSI off.' To test this, he first uses a dedicated 'Slime Sport Gauge' digital tire pressure gauge to confirm the pressure of a trailer tire, which reads 50 PSI. He then connects the generic LIVOWALNY inflator, which reads 48 PSI, and then connects a Milwaukee M18 inflator, which reads 51 PSI. Based on these discrepancies from the known accurate gauge, he confirms that Brian's review about inaccurate PSI readings is true.
Goal: Verify the accuracy of the inflators' PSI readings against a known accurate gauge.
