Review on 🔧 Armor All Tire Inflator: 12V Portable Air Compressor Pump with Pressure Gauge - Ideal for Automobiles, Cars, Trucks, Bikes and More by Jacob Schmidt

I was skeptical when I took it out of the box given the $20 price tag and cheap looks. However, it worked well and pumped up three of my four tires before it got too hot. The instructions say it only takes 15 minutes to run. If you use it on a completely flat tire, be prepared to wait a bit. Otherwise I am very satisfied and would recommend it.
