KeenPower Tire Inflator Portable Air Compressor - Super Fast - 21V Rechargeable Battery Powered Handheld 160PSI Tire Inflator

Can't believe how powerful this is. Adds air very quickly with auto shut off when your set pressure is reached. Great digital readout. Nice long permanently attached hose. That's the weak spot on other inflators. Their hoses are short and removable and strip out leaving it worthless. Not loud either. You see that in many reviews. Read more

Super pumped about this pump! Super excited that the battery had a charge upon arrival and I was able to use it straight out of the box. Charge time is not a lengthy process. Super easy to use. Works really well and pretty accurate. I was able to use the air pump right before the snow storm and my tires have lasted through the frigid air. Read more

This is truly a uniquely designed product. The digital display allows a preset selection for cars, motorcycles and inflatable sport devices with a pictorial selection for each that distributes the right amount of air and then shuts off. Also, the air pressure can be adjusted in 1/2 psi increments either up or down to your desired need. The rechargeable battery pack really makes this device portable. The design of it stands upright without tipping over when placed on the ground. The built in LED light is a nice added feature. The unit can be recharged from a vehicle or electrical house pug. Also, the zippered nylon retaining bag is very nice. Read more

Unfortunately I had to use this tire inflator two weeks after purchasing it. Stuck on the side of the road , at night, in freezing weather and this inflator was extremely easy to use. The pressure gauge is extremely easy to read, and I was able to keep my gloves on while using it. The case provided is excellent quality as well. Read more

The pump is great Read more

Airs up your tires fast and I like that you can set the meter to how much air you want. It automatically shuts off when it reaches that level. Read more

I bought one of these and used it once so far on my minivan to get the tires topped off after the cold weather dropped the pressure on them. It easily reinflated all 4 tires from around 29 PSI to about 36 PSI on a single charge (with room left to spare). I found it so easy to use, that I bought one for my daughter to keep with her in her car up at college (for emergencies). Unfortunately the 2nd one I bought was dead on arrival. The LCD display would light up showing that the battery had a full charge, but the pump would never activate. I returned it as defective and got a replacement and the replacement worked fine. So... all that is to say, it seems like a reasonable device for the job, but you might get one that is defective. Make sure you don't buy it and leave it in a closet waiting for your first use. If you buy one, make sure you try to use it right away. Otherwise, you might find out when you really need it that it never worked at all. Read more
