Slime 40026 Tire Inflator, Portable Car, SUV, 4x4 Air Compressor, Heavy Duty, 2x Pro Power, Heavy Duty, with Analog 150 psi Dial Gauge

I am a person who believes in doing a thorough research of products before purchasing them. Before purchasing anything, I would research all the available options in the market, how they function, their differences, pros and cons, reviews, and then decide on the final product that suits my needs. After that I also do a price research to find where can I get it cheapest but I don't purchase from unknown websites.One fine day as I was about to pay a visit to my grocery store, I noticed the low tire pressure warning on my dashboard. I checked and saw one of the tires quite deflated. I was not at all comfortable driving even to the nearest gas station for inflating the tire. That is when I felt the need for a tire inflator. Moreover, I love travelling and do a road trip almost every month. The tire inflator would come in handy whenever I am on my road trip.My requirement was a tire inflator with very good reviews and that can work from my car's 12V power supply and which is fast - should not take more than 3-4 minutes for one tire. I did not want the one that works from car batteries as I was not comfortable opening the hood and tempering with anything in there. My car's power outlet is rated 12V/10A. I tried searching everywhere but could not find a tire inflator with satisfactory reviews, that works from car's 12V power outlet with less than 10 Amp rating. Moreover, I realised that the inflators that work through the 12V cigarette lighter socket would be slow.So finally with lot of skepticism, thought of going ahead with the one that runs through the batteries. I purchased this one as it had very good reviews and decent price. Below I am noting down the specifics of this product:Used with which car: I used this inflator for my Hyundai Accent 2013 which needs 32psiSound while filling: I would say it is quite noisy. To give an idea, lets say if you are playing music in your car while standing outside the car, you would play it louder than the sound that this device makes. So basically, this device does not make noise louder than the volume at which you listen to music. Moreover, I have street parking and that's where I use this device, so the sound does not bother me at all.Dimensions of the product: In terms of length and breadth, its box resembles a 15'' laptop. The height must be around 4-5 inches. Its not very heavy, with the case it can be easily carried to a distance. We always keep it in our boot, so do not need to carry it as such.What it comes with: It comes with a black suitcase-style box in which everything can be easily and safely stored. It includes all the things that you would need to inflate the car tire - the pump, battery connectors, pump to tire connector, built-in pressure gauge (not very accurate, please see next section), has built-in flashlight, it also comes with different sized nozzles to use for inflating, toys, beach ball etc.Accuracy of pressure gauge: I compared the pressure shown by the built-in gauge with multiple sources (gas stations, pep boys) and found that it is not completely accurate. I use TireTek Tire Pressure Gauge. Its is quite accurate. The built-in pressure gauge shows 2 points higher than the actual. I use the built-in one just for indicative purpose while inflating the tires and then adjust pressure with the TireTek pressure gauge.Ease of connecting: Though initially I was skeptical to use a car-battery based tire inflator, I found it absolutely easy to use when I tried. Follow the instructions that come with this tire inflator, and open the car hood as per your car manual. Make sure to connect the red clip to positive of car battery and black to negative. Always clip red end first and then black end. While removing, reverse it - remove black first and then red. There might be just one problem with its usage. Though the cord connecting the device and tires is long enough, the wire that connects the car battery and device is not very long and you have to keep the device close to the hood. As the on/off button is on the device, it is a problem to use with the rear tire as you have to come to the device to switch it on/off. I and my wife usually use it together, so no problem for us. You might want to refer to this video for using it https://www.youtube.com/watch?v=jRx9vgM6-6YNumber of times I have used it: I have used it around 4 times in last 2-3 months.Price at which I purchased it: $56.40

This compressor is very quick for a 12V unit. It seems to be built sturdily and will likely last a reasonably long period of time.Its wiring to the alligator clips is sufficiently long to connect to my battery in my tall Suburban while still allowing the unit to sit on the ground. That was a MUST as I'm not comfortable with the idea of a compressor like this rattling around the engine compartment with the engine running. The stock hose seems kind of thin, but may be plenty durable for pushing air to the tires. That hose is long enough to reach all 4 tires on my rig, so it will be long enough to reach tires on any full-size pickup, SUV or smaller vehicle.I highly recommend buying the valve quick connect attachment though. Since the compressor switch is so far removed from the air outlet, and since I have an incessant distrust of compressor air gauges, the quick connect will allow you to quickly check air pressure with your own trusted gauge and then reconnect the air hose as needed.The air gauge on this unit is not great. It is a bit hard to read, is inherently inaccurate while the compressor is running and not terribly accurate (+/- 3-4 PSI) once the compressor is shut off. I'm picky about my air pressure since I like to run close to the tire pressure max. If you just need to do a quick top-off to the door-panel pressure recommendation then this gauge is fine though.Speed - wow! You can actually see the rig rise as the tire is inflated. It takes about 2 minutes (slightly less) to inflate a 275/55 R 20 tire from 19 PSI to 41 PSI. At this rate, the air going into the tire is quite warm, so expect the *cold* PSI to come down a couple PSI (my tires settled at 38.5 PSI cold). For those used to using home 120V compressors, this should be standard expectation. As to comparison to home 120V compressors - I'd say this is about 3/4 the speed of a typical pancake compressor and about 1/10 the speed of a commercial tire shop compressor. Very impressive that a 12V unit can be compared at all to a 120V compressor, let alone a commercial one - but this absolutely can! As compared to the variability of gas station compressors, it is about as fast as the average unit available to customers. I've seen much faster gas station compressors, but I've seen much slower as well.The carrying case is convenient, but I can see a time in the not-so-distant future where it won't latch anymore due to the flimsy plastic flap latch. No problem - I'll just use my stubby strap to keep it shut when that time comes.If you air down much, this compressor is a must-buy for value and initial quality.

I am giving this a 5 star review based on the ONE time ive used it so far. I bought this, after way too much time scrolling through all the other ones and resding reviews, because it hooks up straight to the battery, (no worrying about blown fuses) and because it has dual motors. I wanted something that would inflate my truck tires faster than my last one, (which was a plug in and took about 10 min to inflate 10psi). I keep my tires at 80psi and check them every month or so to keep them topped off. I had one tire down to 70psi, so when i got this bad boy i hooked it up out of the box, (pretty straightforward, easy and fast) and turned it on. It had my tire from 70 to 80 psi in about 2 min. Its fairly quiet (as quiet as one of these can be) and packing it back up in the nifty carry box was a cinch. It all fits nicely, no cramming stuff in and trying to make it fit. Oh, and the reach on the hose is awesome. It went from the hood of my truck to the back driver tire with hose to spare. (F150, 6foot bed, super cab) I will say i dont think it will reach if you are trying to hook it up to something hitched on the back of a truck. I keep all tire changing\patching necessities in my truck at all times, as i am not fond of being stranded on the side of the road. I dont know if this would be able to inflate a completely flat truck tire without overheating... But i do believe it would put enough air in to get to a gas station with an air pump. As for car tires, probably would be able to do the job. Compared to all the other similar ones out there, i think this one has the durability and is heavy duty enough to go the distance. Also, did i say i love the carry case? Packs up nicely and slips right under my backseat.
