I've got this device very cheap for RM43 or approximately around 9 USD from local Mr.DIY store. It is quite small and portable powered by 12 Volt car lighter slot. The power cord is long enough to reach all 4 tires (front and rear back) and but i am not sure exactly how long probably around 3 to 4 meters. The inflator tube fitting is using screw which is exactly what i am looking for because it will snugged fit right into the tire inflation tube without air leakage.
Upon the first test the sound is quite loud and the startling sound almost makes me doubt it can pump standard car tire - but that changed after i have tested it. According to the manual the device cannot operate more than 12 minutes continuously due to overheating but that is the least of problem to concern about because it takes 1 or 2 minutes only to inflate a single tire. So not to worry about it because we are not going to use on industrial scale.
The test was done with my Perodua Alza initial tire pressure around 29 psi ~ 30 psi and i am going to achieve it's ideal pressure which is 230 kPa or 33 psi as standard on the car manual. So after the test it takes only 1 to 2 minutes and the result is very satisfying. There are 3 basic thing to notice about this Coido tire inflator device.
1. The air tube screw - making it very tight and snugged fit to pump and prevent air leakage
2. The gauge meter - quite accurate as good as the one provided by petrol station
3. The power cord length
The gauge meter are presented in 2 scales
1. lb/in^2 or mostly known as PSI (Pound per Inch Square) - it's the black outer meter reading
2. Bar - red inner meter reading
