WORKSITECordless Tire Inflator Air Compressor, Battery Powered Car Tire Pump, Portable Handheld Air Pump with 12V Car Power Adapter Digital Pressure Gauge for Cars Motorcycles, Gray

The media could not be loaded.  I decided I needed a portable tire inflator and chose the Worksite tire inflator, partly because of operation and dual power – 12v from the car or 20v from the included battery - and partly because of the $20 off at the time.I charged the battery before I used it the first time. I could have just started using it since the battery came nearly full, but I topped it off to make sure I had a full charge to begin.The tire on the right side of my utility trailer has a slow leak and just happened to be flat at the time, so I thought that would be a great first test of the tire inflator. That tire is rated for 50 psi.I pushed the nozzle fully onto the air valve on the tire and clamped it on. I pressed the On/Unit button to turn on the LCD display and used the plus (+) and minus (-) buttons to set the inflator to 50.0 psi. When I squeezed the trigger, the unit started pumping air into the tire. I set the unit on the ground and let it continue on its own. When it reached 50 psi, it shut itself off, so I could disconnect the nozzle.The inflation lasted about 4 minutes. My total time at the trailer was about 6 minutes.The inflator comes with other attachments and a handy bag, which holds everything and would be easy to stow in a car’s trunk or even a backpack.Just a couple years ago, I was on a road trip in a rental car with tire pressure sensors. When I had several miles to go to the next service and just about as far if I had turned around to go back, the right rear tire set off a low pressure alarm. Since I had no spare and no way to pump up the tire, I had to keep going and hope I wouldn’t have a blowout. One of these tire inflators would have been great to remove the worry about making it to a place where I could use a half-dozen quarters to add those few pounds of pressure back to my low tire. For the price I paid for this tire inflator, I figure this is great insurance against having a repeat. If I pick up a nail or something, that’ll be another story.

This is a wonderful tool. Easy to use. Light weight. Great carrying case. Charged battery (new) less than an hour and one half. Great price. Was able to inflate 8 tires (2 cars) in less than 15 Minutes. So far, glad I decided to purchase this one. Will make sure I have it in the trunk of either car when out. You never know when you might need some air in your tires. Makes a great gift.

One of my cars is only driven on the weekends or when the needs arrive. Every few months, the tire pressure indicator would light up, which would require a trip to the local service station to put air in the tires. Recently they began charging access to the air pump and vacuum cleaners. Not a biggie, but it's not often I carry coins. So now its become an inconvenience.This air pump was on lightning deal, so I though might as well give it a try. I ordered it, and 7 days later, Amazon notified me that the package was lost somewhere in San Francisco. No fault of Amazon, which sent out a replacement right away.When you first get this, charge the 20V battery. It also comes with a 12 volt CLA, and a nice carrying case. To use:1) Attach the air hose which is easy to attach to the tire stem.2) Press the middle button to show current pressure.3) Set the desired tire pressure by pressing the left or right button..4) Press the trigger and that's it. It shut off by itself when it hits the pressure you set.5) Disconnect the hoseIt took about 90 seconds to go from 28 PSI to 36 PSI. Not fast, but not slow either. It took less than 10 minutes to do four tires.Why 4-stars? Design and heat dissipation. This was not designed to be held in your hand while using. You would think by looking at the design and layout that it could be held in your hand. Instead, place on the ground. Trust me. After pumping 4 tires, it gets really hot. I mean really hot. The handle, the hose, the main body, everything, except the battery. I tried it again the next day on a different car with 2 tires and it got hot after a minute of operation. (Heat is normal for air compressors, but the handheld design is deceptive - hence the four stars)This is a good recommendation overall:1) It's a good tool to keep in your trunk.2) It's compact with a nice carrying case.3) Has both battery and CLA power options.4) Saves a trip to the service station.5) Optional tools included to pump sports equipment and flotation devises.

I was able to top off all my tires in less than 5 minutes but I would not believe I could fill one of them from 0 to fully inflated in 5 minutes or less. I would say I took a little over 1 minute each to add 3 lbs of air.nice product and great price

Works as it should

I just got it today. I aired up 3 sets of bicycle tires for 22 lbs to 40 lbs. Each tire took less than 30 seconds to fill. Read the instructions, set the poundage and it shut off automatically. So far, So good 👍

I have a tire that occasionally needs air. It's hard to find an air machine in gas stations anymore. This not only works but you set the pressure, turn it on and walk away. It shuts off at the correct pressure.

used it once and it was very easy to use!
