Review on 🚗 Aocoom Portable Air Compressor: 12V DC Electric Auto Tire Inflator with Pressure Gauge and LED Light for Car, Bicycle, and More! by David Garnic

Bought because of the attractive price and the possibility of preset pressure for inflating bicycle tires. It is nicely packaged and comes with the usual set of nozzles and needles for inflating beach toys etc. However, the first purchased turned out to be defective - when turned on, it did not puff up. Instead of the usual supercharger motor sound, there was an unusual hum and the cable got hot, so I sent it in for a replacement. When I plugged in the replacement, the same thing happened: buzzing but no gas. I unplugged it immediately and tried again and after the initial buzzing I heard the compressor start up sound and it worked fine. I have successfully inflated 5 bike tires to 65psi and will update this review.
