I tried Today: Pros: - 30 psi to 34 psi took 5 sec i was surprised to see. May gauge reading not accurate. - Wire length is sufficient to reach all tyres. - little heat up. - Sound is managable.
Cons: - nozzle should be little more strong.
Users please follow the steps as mentioned in manual. While fitting the nozzle, be quick so that less air leak. Also, fit nozzle tight. For better power, make car engine on. Make sure, the cigarette charging point is fitted tightly. Always switched off the device before pluging in or out and before fitting nozzle in and out.
So, at first trial, this device was wow. lets see how long this will go.
------------- Day 3: I checked on Gas Station and I found reading was accurate as shown in this tyre inflator. Next I tried on a flat puncture motorcycle tyre. So, from 3psi to 22psi it took nearly 14 sec. I was surprised, it's very fast.
