Review on Black Stop & Go RCP Mini-Air Compressor by Christopher Bacho

This small compressor is designed for emergency or intermittent air supply for motorcycle, bicycle, etc. The label included in the package clearly states that it cannot be used on car and truck tires. It is not intended for continuous operation or frequent use. Its purpose is to be there when you need it and hopefully you don't need it. If you use this often I doubt it will last long, but it's just an educated guess. I deflated my bike's front tire and it inflated it from completely flat to 36psi in about 3.5 minutes. This is a typical 17 inch wheel size for a sport bike. Now that I know it works I put it in the trunk of my bike and hopefully never have to open my bag again. BENEFITS: Compact and lightweight Comes with a protective carry case and a variety of power connection options The power cord is about the length of a motorcycle so you can reach either end. Has an LED on the top to help you connect to the bus at night. Has a yellow button to turn the compressor on and off. not loud. For its tiny size, it inflated my tire pretty quickly. CONS: The sensor is useless or will be soon. It jumps 10-15 psi on each stroke of the compressor and then returns to the tire pressure gauge. So when you start the compressor, the arrow gets blurry like a fan blade. When I first hooked it up to my tires, it showed 36psi, the correct pressure. After a cycle of deflation and inflation with a small compressor, which must consist of thousands of cycles of shaking the gauge needle, the needle read 6 pounds low with the pump off. If you're familiar with pneumatic tools and feeders, you'll understand that they didn't place the hole between the gauge and the feeder, or they got it wrong. Rather than modify the pump to protect the gauge, I just carry mine. Do not rely on this pressure gauge to show your actual tire pressure. All in all, an almost ideal design for an emergency air pump.
