Review on Portable Air Compressor Tire Inflator with Digital Pressure Gauge and LED Light - 150PSI, 12V DC Auto Tire Pump for Car, Bicycle, and More by Chris Maurer

Very light weight and fast inflation. I increased my tire pressure today and the observations from my first use are the advantages: 1. Compact size and light weight2. Wires can easily reach both front and rear wheels3. rapid inflation. It took 70 seconds to fill the pressor from 29.5psi to 34psi4. flashing LED lights5. automatic shutdown after reaching the set pressure6. Cons of the digital pressure gauge: Makes noise, but I think that's typical of inflating tires for drinking. a good emergency device and the extra adapters are useful for basketballs and soccer balls.
