  • Surprisingly effective and easy to use!
Color: Blue Size: Large
I've tried a lot of DC powered inflators in my lifetime, and these are Far and Away the very best! I've had them in my trunk for over a month and finally got a chance to use them. * My car was pulling slightly to the right and the tire looked a little bit low. When I clamped on the tire-pump style connector, it sealed the valve stem completely, without the hissing that usually goes with these types of connectors. * When I plugged the power cord into my cigarette lighter, the LED panel immediately displayed six and a half pounds of pressure, even though the switch was set to off. The controls were quite intuitive, so I didn't even bother to read the directions. I set the pressure to 30 lb, which is what my manual recommended. I turned on the switch and it immediately started pumping. * Although it was a little noisy, it was much quieter than many of the ones I've used before, with the added benefit that it didn't dance all around the floor like the others tended to. * Get reach 30 lb in just a couple of minutes, and shut itself off. The 30.0 displayed clearly in the LED window, so I could read it standing up. I repeated the process on my other three tires, two of which were fine, and the third needed just as much air. The whole process took under 10 minutes. * I am going to buy one of these for my daughter and make sure there's one in the trunk of every car I own. ... show more

  • Buy two!
Color: Yellow Size: Large
They should give a good offer on two of these, and here’s why: I read reviews carefully before deciding on a purchase. I also try to determine if the writer might have trouble understanding and/or following instructions. The one problem I noticed most often in the one-star reviews was that the users failed to follow directions. First, you need to keep your motor running while using this device. If you try to use this off the car battery alone, you will risk draining your battery or blowing a fuse. Second, do not try to pump up all four tires at once. These devices run hot. Even the hose was very hot to the touch. So, I purchased two of these machines that would allow me to pump up tires to my 2006 Dodge Caravan alternatively. While I’m pumping one tire, the other device is cooling off. I made certain to touch every part of the machine for a temp check, before reusing it. I guarantee that if I had only purchased one tire pump, and used that pump to fill each tire consecutively and immediately, I would’ve blown out the machine. It begins running hot on one tire. So, with one machine, I would’ve been forced to wait ten minutes between each filling, or risk losing the machine, altogether. Buying two pumps is more expensive, but if I pumped each tire without a cool-off period, I would’ve been forced to buy two anyway, right? AND I would’ve lost one machine in the process…AND I would’ve had to wait a few days for delivery, instead of the recommended ten minutes for cooldown. So by buying two of these, and alternating their uses, one can be cooling down while the other is being used. Easy peasy, bumble beesy! Now, another complaint was the automatic shutoff. Personally, I set it above the recommended PSI level to make up for any air lost during hose removal. So if it says “44 psi”, I set it for “45 psi”. Then I watched the dial as the number climbed. As soon as it reached the number I selected, I shut off the machine. I’m not sure why someone would want to depend on the automativ shut-off to complete the task. The automatic shut off is not intended to be a feature of luxury; it is simply a safety feature, in case the user became distracted. The tire pump, like most machines, should never be left alone to complete a job. In all reality, the tire pump should not require ASO; but the manufacturer included it to compensate for unexpected distractions. So does my ASO feature work? I have no idea, and I don’t care. Because when I run the pump, my total and complete focus is on the pump. If a distraction occurs, I am prepared to turn off the machine so I can deal with the emergency at hand. Machines are not built for the multitaskers. Do I recommend this? I have nothing else to compare it with. I will say the numbers climbed in increments of .05 psi (21.0…21.5…22.0…22.5…23.0…23.5…etc). So the pressure climbed .5 in 6-9 seconds (ie., climbing from, say, 31.0 to 31.5 took anywhere from 6 seconds to 10 seconds, but the average time was 7 seconds). So for a tire to begin 20.0 and inflate to 45 psi (my vehicle was sitting for two years), it took no longer than 10 minutes a tire, and I’m being generous. And it would’ve taken twice as long if I had only purchased one pump. I love this machine. Have you tried filling your tires at Wawa, lately? They’ve cut off all their pumps! Other stations require insertion of coins (who carries around coins, these days?). We are either driving around, trying to find a decent air pump (while driving on low tires, mind you), or waiting in long lines to use the only working pump in town. It’s so much more convenient to fill my tires with two air pumps that I don’t have to wait to use. Once my tires are filled, I can keep one pump in each car, in case a tire gets low. I should not have to fill all four tires while on the road. But if I do, I’ll just have to wait ten minutes as the instructions suggest. This is one if the wisest purchasing decisions I’ve made recently. They also arrived supplied with alternative nozzles for bikes and sports equipment. I’m not sure if I’ll use the air pump for balls and bicycle tires, but it’s good to know I have options. I was not paid or coerced into writing this review. ... show more

  • Works Better Than I Expected.
Color: Yellow Size: Large
This tire pump inflates faster than I thought it would. It really compact so storing it anywhere in a vehicle shouldn't be a problem. Manual is very clear & straight forward unlike other products I've purchased in the past. The cord for plugging into a vehicles port is fairly long as well which means you can get the pump to any tire (at least on my vehicles... a mid sized car and a jeep). Really happy with this item. ... show more

  • Do not even try to order the “Large” unit that is offered!
Color: Yellow Size: Large
The pump seems to be fine. HOWEVER...the large model apparently doesn't exist. I ordered the LARGE yellow pump for $32.98, model A220B (described as plastic). I received the MEDIUM yellow pump for $29.99, model CZK-3631 (described as metal, but actually plastic, too). Amazon customer service offered to exchange the wrong one for the right one. However, I kept the wrong one and re-ordered a LARGE myself, because I wanted to compare the two before returning the wrong one. When the second (supposedly large, model A220B) one arrived, it was absolutely identical to the MEDIUM model CZK-3631!! Now I not only have TWO of the model I didn't want, but twice I have paid the higher price (+ tax) that was listed for the large--and I still have to return at least one. The listing is wrong (apparently there is no medium and the only reference to A220B anywhere on the order is on the box, and it is not a model number but the ASIN (ASIA220B-US). I suspect that the phantom LARGE model is not sold in the U.S. because in the listing its item weight and air flow capacity are listed in kilograms and LPM, which are non-U.S. units. I have requested a return and refund for one of the pumps PLUS the difference in price + tax on the one I’m keeping. I expect to receive a full refund for the item returned but likely will have to eat the difference on the one I’m keeping, so I will have received a unit that isn’t want I wanted and paid more for it than I should have. Do yourself a favor and don’t even try to get the large pump. ... show more

  • Small, convenient, reliable
Color: Yellow Size: Large
I got one of these for my daughter to have in the car, so that she can top up the tire pressure any time she needs it, without having to look for a gas station. Great buy. It has a programmable feature to stop at a specific pressure, so it operates completely unattended. The extra accessories for inflating other inflatable objects are a nice touch. ... show more
