Kensun AC/DC Tire Inflator Pump for Car 12V DC and Home 110V AC Swift Performance 2.0 Portable Air Compressor Pump for Car and Home

So far I’ve used the DC (car plug-in) 6 times for a slow leak in my tire and the pump has been excellent. Pros: I like being able to put in the target psi and pushing the button and letting it do it’s thing. The pump shuts off automatically when it reaches the target. I’ve used the flashlight function once at night and it is adequate for unscrewing and screwing the cap onto my tire. The digital screen is backlit too. The pump is quieter than my dad’s old one from the 90s or any stand alone gas station air pumps and works faster. I like the zippered carrying case it comes with and the DC cord fits tightly into a compartment on the side of the pump. Cons: The pump is still noisy. I’m not sure I can really complain about this though, for a portable air pump it’s not bad. Overall, I’m happy with my purchase and keep it in my car at all times.

The AC function stopped working after two days. I emailed customer service and 4 days later I had a new one sitting on my doorstep. The inflator works great and handles my car and truck (F 150) tires equally well. I like having both AC and DC capabilities and the gauge does indeed work to within 1.5 PSI which is good for this type inflator. As far as noise I would not say it is quiet, but the noise level is very tolerable especially compared to an old inflator I used to own. It is fast enough unless you are starting from zero. I was able to top off four car tires in under 10 minutes (about 6PSI each). One small drawback with this model is that the inflator hose and AC cord are packed in the same cubby which means you probably need to unpack both even when using the DC function. I would definitely recommend this inflator to a friend.

April 11th: I loved the way it screwed into the stem as I am rotten at holding the air piece and tire stem together. That made it for me. It does take a long time to fill but that is obviously because of its affordability. I LOVE that you can use it by the plug instead of cigarette lighter. The was the other selling point to me. I think this is a great thing for people with weak hands or lacking in dexterity. I have only used it once so far. August 26th: I still love this and it is holding up nicely. It shuts off when it reaches the pressure you set. I have used it multiple times at the point and the case it comes with is really nice too. You need to get a baggie and binder clip to make sure the presta valve doesn't fall out but that is no big deal.

I could have bought another brand, but what caught my eye was that the motor was NOT made of plastic! It is unbelievable to me that some manufacturers would sell customers a plastic motor! This is the first pump I have owned with an automatic cut-off and dual power (AC or car 12V DC outlet). This is a great convenience for a number of reasons. In the past, I would have to go and get my keys and then put the car in the "accessories" mode. Not as easy to do compared to the old-fashioned way where you simply turn the key toward you. Then, when one side of the car was done, you would have to open the windows and pass the pump out the other side. This procedure is now obsolete. Yes, I need to use a short extension cord, unless I take pains to park near the AC outlet. Using an extension cord is no trouble at all. Another great convenience is that in the past, I would have to over-fill the tire and let out a little air at a time while measuring with a separate pressure gauge until the correct pressure is reached. With this new pump, you only have to go through this procedure one single time for just one tire. In my case, my tires require 32 lbs of air. I like to put in an extra pound as pressure will go down over time. I found that if I set the new pump to 34.5, it will pump the tire up to exactly 33 lbs. Now I can use just the new pump and do away with the separate gage. I am guaranteed to get my 33 lbs, no measuring required.

This product is not worth it even on sale. Three separate times now I have attempted to use it to inflate auto tires when the low pressure signal went on. The unit was attached to the tire and appeared to be inflating the tire, shutting itself off when it said it reached 35 psi— but the auto sensor still said the tires were low at 31 or less. Useless for its purpose.

Easy instructions, done in less than 10 minutes. Both AC and DC cords hard to replace in case after use. Maybe needs a little more storage room or more flexible cords? Could also use a battery cable to lighter jack power converter. Does include a bayonet extension hose, very convenient, but didn't realize unit comes with it. Will re-read directions , haven't found directions to register warranty, either.

I have an air pump that plugs into the cigarette lighter on the car but it takes quite a while to fill a low tire and does not shut off automatically so you have to monitor it and turn if off when the pressure gauge reaches the desired level. When I had to do that in 5° F winter weather I decided I wanted a pump that will operate on AC and has automatic shutoff, if for no other reason so I can sit in the car with the windows closed while waiting for the tire to fill. I used this unit for the first time today and it worked great. I was pleasantly surprised that the AC cord that plugs into the wall outlet is 3 meters (10 ft) long, not the 1 meter (3 ft) described on Amazon. I had to set the auto shutoff two lbs higher to reach the desired level (e.g. set it to 35 pounds to shut off at 33 pounds) but that's no big deal once you know the adjustment. Recommended!

This is a great tool for anyone who depends upon their car to be ready to go at all times. A flat or slow leaking tire can stop the most expensive vehicle in its tracks. To be able to regulate tire pressure in the privacy of your garage or at the side of a road is great. It removes some of the anxiety of the common problems experienced with tires in a simple and effective manner. The self contained dual powered unit allows for quick and accurate servicing. Highly recommended.

It's works perfectly for all air filled equipments

Not enough attachments for things such as air mattresses & the air hose should be longer. I was happy with the speed at which it filled my bike tires. I would say it is overpriced for the quality of the machine. For $170.00 bucks I would think attachments would and should of been considered.
