SuperFlow Portable Air Pump, 12 volt Air Compressor, Tire Inflator 140 PSI, 12v air compressor for Cars, Trucks, and Bikes.

I bought this SuperFlow compressor from Amazon over a month ago and used it every 3-4 days since then to pump up a slow leak (which I finally got repaired yesterday - a nail in the center of the tread). Here's my $0.02: My old 12v compressor has a quick-fit, clip-on fitting that keeps slipping off the tire valve. So I decided to replace it with a compressor that has a threaded fitting that screws onto the tire valve. When I found this SuperFlow compressor on Amazon and read the reviews it appeared to be just what I was looking for. When it arrived, I was surprised that something so small was so heavy. I was pleased by what appeared to be a well-designed and well-made unit in every detail. Here's what I like: All-metal construction (which is why it's so heavy). A fitted nylon case with dual zippers and a flap with two buckle closures. Unlike my old 12v compressor, the air hose unscrews from the compressor body for easier storage in the nylon case. The on-off switch is on the compressor body, and not the power cord. That cord is long enough to reach every tire on my LS460 with at least a foot to spare. The top of the compressor has a built-in dial-type pressure gauge, with a removable cover, that is claimed to be accurate to +/- 10%. But how it looks and feels tell only part of the story; the other part is how well does it work? The SuperFlow is much faster and quieter than my old compressor. Sure, there is a little air loss when you unscrew it from the tire valve, but it's no big deal. I realize that the engine should be running when you turn the compressor on, but I wanted to see if it drew so much amperage that it would blow a fuse in my lighter circuit. So I ran the compressor with the ignition in the on position (my cigarette lighter is switched) and the engine not running, and I had no problems. This little pump is big on design, construction, and performance. It exceeded my expectations. I'm glad I spent a little more because I got the best!

I bought this to replace a compressor from Slime Co. that I just sent back. The Slime one ran for 5 minutes, and smoke started pouring out of it. Stopped it, let it cool overnight, tried again, same thing. It came with a note (not mentioned in its advertising or on the box where you can find out before buying) that it should not be run more than 10 minutes at a time, but it didn't even last that long. This HV35, while not quiet, is noticeably quieter than the Slime Co. one. And it pumped my 7-gallon air tank from 50 PSI to 105 PSI in about 15 minutes. That's perfectly adequate performance, and quite good for the price. The sheilded output tube got pretty warm during that time, and the pump body got hot, but that didn't seem to affect its performance. No smoke, no slowing down, or other signs of distress. I consider this compressor to be a very good value for the money. It would be nice to have a clip-on output spigot rather than the screw-on one, but that's a minor quibble. It comes with a peel-off label on the gauge, that says it might read as much as 10% higher or lower than the actual pressure it's measuring. I found that to be true - this one reads about 10% higher than three other gauges I measured it with. PROS: Compact, not as noisy as other compressors, takes reasonable time to pump up an air tank. Low price. No performance problems. CONS: Gets kind of hot, but most compressors do. Screw-on spigot instead of snap-on. Gauge needle quivers as it runs. These are all minor complaints. I consider this compressor to be a good value for the money. It would be nice to have a clip-on output spigot rather than the screw-on one, but that's a minor quibble. I was looking for a compressor that would do the job and not give me the grief the cheaper Slime Co. one did, and this one fills the bill.

In pile of deceptive advertisement, gadgets and attachments that don't need to be part of the basics, devices that don't work by design,..... this one made it past first test. I inflated both bicycle tires in less then 5 minutes and 4 letter word never crossed my mind. Looking at compressor, simplicity is a key in functionality, hose screwed on both ends without any flaw, sealed valve instantly. Tires went from no pressure to 30 PSI literally in matter of 15 seconds or so, I keep two small 12V rechargeable batteries in a garage with cigarette lighter attachment to leads so didn't even have to loosen up the power cord. Next, I let some air out of truck tire and repeated the process, tire pressure went back up quickly with no sign of struggling, threads are perfect on both ends of rubber hose and it is easy to engage and disengage it form compressor and valves. Simplistic design with handle is very effective, minimum amount of plastic used, has potential to survive few bumps and bruises. !40 PSI in such a small package makes it good choice for carrying in car trunk or behind back seat of a truck. One thing I am not so hot about is label burned into pressure gage window stating that accuracy varies by +/- 3 psi, it interferes with dial but this in itself is not an obstacle because I use another gage to fine tune final tire pressure. If it dies on next attempt to use it, I'll come back with sticks and stones, but as of now, I recommend this unit for its good value, small yet potent capacity, portability, simplicity and functionality. I am sure I could work this thing in pitch black darkness but small flashlight in my pocket can be useful as well.

I'm buying one for each of my male relatives for Christmas (at least the ones I like). The ultimate in functional simplicity. Beautifully made---you could tell your friends that it is standard equipment on high-end Mercedes or BMWs and you'd be believed (but remember to take off the "Made in China" sticker). Actually, the pump (in its attractive zippered black canvas case) will probably perfectly fit in the recess in the trunk of German cars (which is meant for the first-aid kit required in Germany). Having used the pump several times---it has worked perfectly, pumping up tires promptly. Unfortunately, you need to unscrew the supply hose to put the pump away in its canvas case. A simple right angle connection would be an improvement. Note that you also have to screw-on the supply hose to the tire stem---there is no quick-connect connector. Nevertheless, the connection and disconnection is easy---just a quick twist clockwise or counter clockwise---much easier than my experience with other less-well-built tire pumps with screw-on connectors. MAJOR CAVEAT: Unfortunately, the screw-in connector will not screw-on to one of the valves stems of my new VW Golf. The valve stems contains electronics, and so, is too expensive to replace. So, I purchased Slime 2045-A 1-1/4" Metal Valve Extender to use as an adapter. It works, but once the valve extender is attached, the screw-on connector no longer rotates. So, you have to install the valve extender first, then attach the screw-on connector to the valve extender---not too big a hassle for one tire with a odd valve. I also find that it takes some effort to screw the valve extender tight enough on the tire valve for the combination to open the valve. A little oil or grease (preferably silicon grease Permatex 22058 Dielectric Tune-Up Grease, 3 oz. Tube on the threads of the valve, valve extender, and screw-on connector, make it easier to get the connections tight enough. CAUTION > If you inflate a fairly flat car tire, the red portions of the compressor can get hot enough to burn your fingers, and certainly too hot to put away. Just let it cool off. > After a while, I found that the built-in guage was off by 5-pounds or so, and in any case the markings are too close together to distinguish a difference of a few pounds (which can be too much uncertainty for car tires). So, use the built-in gauge as a rough guide, but use a separate dial-type manual (not electronic) pressure gauge designed for the approximate pressure range of your tires to fine-tune the pressure in your tires. For example the 0-35pd Viair 90056 2.0" Gauge (0-35 PSI) Tire Gauge with Bleeder Valve or the 0-100pd Viair 90072 0 - 100 PSI 2" Tire Gauge with Bleeder Valve To see my "Put together a tire maintenance kit" and "Repair a tire valve" guides, click on "See all my reviews" above, then click on "So you'd like to know" guides on the left side of the page

I have a very slow leak on one of my $200 SUV tires (2-3 PSI leak per year), and my motorcycle needs a little air every couple months -- and then +10 PSI every spring after it's been idle for the winter. This product works as advertised, and the pressure gauge is correct (I get the same reading as compared with the $25 accutire digital bought in 2006) for me. I've used this to blow up inflatable swimming pools and various other kid toys...and I've not wished for additional attachments other than what comes in the box. It's entirely possible that there are better compressors, more quiet, cheaper, etc., but this $35 compressor meets the needs for my large SUV, motorcycle, and kids toys. It's not loud (to me), it's quick enough (for being tiny and inexpensive), and I'm grateful to have it as it saves me frequent (and potentially unsafe) motorcycle rides to the gas station. For the price, I don't have any perfect-world product improvements. It took ~2 minutes for my motorcycle tire to go from 20 PSI to 36 PSI, and if I'd wanted something faster I'd have bought a more expensive compressor.

Very good air pump. It's much better, quieter and faster than my old one. This is well worth the extra money to have a really good tool instead of just an entry level pump that struggles for a long time. We liked it so much that after a few months, we just bought another for my better half. The pump is surprisingly small, especially for how quickly it works. We're very pleased with it.

Got this after having a screw pierce my tire and making it home while stopping at a service station along the way. Tested it out and it performs as one would expect from a small compressor. You won't get that sudden 'gush' like you do from a full sized one, but for a little compressor it does the job. Comes in a small cloth pouch which is great for tossing it in the car. I don't know why there are complaints about attaching/detaching the hose, it has a thumbwheel that makes it easy. And I prefer the screw on connector to a tire vs. the quick latch types. I always had trouble with the quicklatches if you didn't get them on just right. 10/31/11 - I've noticed some people worried about blowing a fuse. You should have the engine running when you use this to avoid that. Also, it amazes me that some people knock this for cord length and/or 'cigarette lighter plug'. The total length is in the description and there are pictures of the lighter plug if you look. Longer cords make for bulkier items and as it is, it will reach your car tires. Note: 12 Volt is NOT going to plug into a wall socket without some sort of adaptor). As far as longevity, I made my review after only having this for a few weeks, so that could be an issue?

First use was a test run in the driveway. This compressor is slower than slow! Bought it to inflate truck tires after dropping pressure for a smoother ride on rough desert roads. Needed to add 30 pounds in a 17” tire. I gave up after 30 minutes it had added 25 pounds to the tire. I don’t have 2-3 hours to top off the tire pressure. If you have a full size long bed truck park with the valve stem at 9:00 so the cord will reach. This might work for small low pressure bike tires but not higher pressure requirements for truck and trailer tires.
