I'm using Coido #2124 DC 12V Air Pump bought from MrDIY at RM36.32. So far so good. It's small and easy to store. I don't expect much since its cheap compared to those Michelin brand with few hundreds ringgit. It might not have very accurate meter but it does it job by inflating car tyres. If you want to be accurate, you can purchase separate gauge to check the tyre pressure. 2 items add together still cheaper than branded electric air compressor/inflator. Furthermore, if its broken I also will not feel pain.
