Review on 🚗 Kobalt 12-Volt Multi-Purpose Portable Car Sport Air Inflator: Efficient and Versatile Solution for On-the-Go Tire Inflation by Lance Jenkins

Does exactly what it's supposed to do. Not too loud. Generates air quickly enough. Inflated a nearly flat tire to 38 pounds in 4-5 minutes. Inflating the tires takes less time. Much faster and quieter than previous 12V tire pumps. Operation with 120 and 12 volts. The digital display is excellent. The best feature is that it shows your current tire pressure when you attach it before you start inflating. It switches off automatically when the desired pressure is reached. Works best with a Schrader valve stem as this is the standard jet and does not require jets. This type of stem is used on car and mountain bike tires. After use, everything fits securely into its compartments. The Presta valve jet must be inserted into the pump jet. This is the type of valve stem found on high pressure road bike tires. I only gave these four stars because you need to hold the nozzle in place for the Presta nozzle to work properly. Otherwise, the tire will not inflate because it will deflate as it inflates because it will not seal by itself even after the thumb latch is properly closed. Also, when the nozzle is separated from the valve stem, the o-ring is removed and must be reinstalled on the nozzle before reuse. I also have to use needle nose pliers to get the presta tip out of the nozzle. I have not used any other attachments. If you only want to use this on Shrader valves then this is a great product.
