Black & Decker ASI300

I really like the fact it runs off both AC and DC. The auto shutoff is accurate and convenient to get the same pressure for each tire. DC cord storage is poor ( rubber band it ). This unit is no fast than those 8.99 specials, but it does as good a job and is very convenient. It was a warehouse deal, so the price was right and my friends unit isn't any faster.

I tested it and was pleased with the results and the shipment was on time.

Took it out of the box, plugged it in and it wouldn't work. Tried several different outlets, nothing, not a breath of air, not a sound. packed it up and sent it back.

I love it! Shuts off when your chosen pressure is reached, so you can set it and forget it. Also, I find it very convenient in that it can be powered either from a wall outlet, or from a 12 volt dc source in your vehicle.

Useless piece of junk. Where do I even start with this: 1. The gauge is miscalibrated. My tire pressure showed 28psi on a standard gauge. I set the auto-shutoff gauge on this to 32psi and the unit would not turn on. When I turned the dial all the way to 160psi, the unit turned on; the reading of the pressure was 100psi. 2. The 12V cable is stowed in the same slot as the power switch. To turn it on, you have to pull out the cable. 3. The power switch is hard to reach. You have to lift and turn the unit to locate and push the switch. 4. Takes a long time to inflate. 5. The AC cord is just about 12".
