ALL-TOP 12V Air Compressor w/LCD Control Panel to Preset Target Pressure, 150PSI 12.35CFM Air Pump Inflator for Overland (Dual Cylinder)

This pump is by far the best portable pump on the market. The inflation speed, digital read-out and auto shut off are the nice features to have after getting off the trail. The air line can easily reach all four tires and it fits nicely in the back of the jeep.... BEWARE....Like all air pumps, it does get HOT after use, so be careful when storing it before it cools down.Thank you "ALL-Top" for making a quality product !!!

It is WAAAAY faster than your average $20 inflator made mostly of plastic, and this thing is built like a tank. I've only used it a few times, the most strenuous was taking two 34" tires from 25-30psi to 58psi or so. Obviously things go faster on the low end, but the upper end ain't no slouch either.I can see the weight/size of it being inconvenient for some people, but am fairly certain anyone bothering to look for this class of inflator is not the sort who would be bothered by such things. You'll probably be more bothered by the pressure gauge/shutoff, which was fairly spot on when I did some testing.Later, when I didn't have a physical air gauge, I let it go through the paces and it ALWAYS buzzes one of the longer cycles near the cutoff, takes a break, then gives it one more fart and stops. Watching the numbers and barely paying attention to the runtime, something seemed a little off. Yoinked the hose off the valve stem, put it back -- dead on same reading. Yoinked the power, yoinked the hose, clamped 'em both back on and it read a few PSI higher. Well, I know how uptight some people are about things needing to be precise, so I was just putting this out there.We all get it. Pressure gauges/switches ain't rocket science, and at this price you'd expect better. Well, I don't. The pressure switch probably using a piezo crystal, pressure is measured close to the air source which is subjected to massive temperature change, and the air hose has a fairly small internal diameter. That's a lot of moving parts (not really, but really) over a fairly long distance, and the electronics can only make a calculated guess. It doesn't know air temperature, tire size, skull thickness, etc. Maybe it under inflates a hair, maybe it over inflates a hair. Whatever.The shutoff feature is there to keep things safe in case you need to step away for a minute. If you want an inflator that shuts off accurately within 0.1 PSI, get a wimpy one that takes 30 seconds or more to put 0.1 PSI in. That way you can go in the house and make a sandwich while you wait, because you get grumpy when you're hungry. Alternately, get this thing plus a deflator attachment and a good pressure gauge. Heck, the pressure gauge is essential anyhow as you'll want to occasionally check this thing's calibration.For me, this thing delivered exactly what was desired: it made the tire round and self shutoff at close the f enough. This was the more than I ever thought I'd spend on an inflator, but far less than I've wasted over the years on crappy ones. Money well spent.

Have had this a few months and used it probably 30 times in that time. We live in Colorado on the Utah border and wheel in Utah frequently since we are retired. We have a Chevy Colorado ZR2 bison with 35" tires. We also bought the All-Top 4 tire inflation/deflation system. It takes us about 3 minutes to air down from 38 psi to 16 psi using the 4 tire system (once it is connected up, of course). We consistently air back up from 16 psi back to 38 psi in less than 6 minutes (again, once connected up), which is quite impressive to me. I initially used the All-Top on-board pressure stop controller, and compared it against the Chevy TPS readout in the vehicle status or air-down mode screen. The All-Top would stop a few seconds a few times airing up (as advertised). It seemed to match the Chevy's TPS within a psi or two. I usually just use the Chevy TPS now, and do not set a pressure on the All-Top so the All-Top does not stop at all ... it just keeps pumping while I watch the Chevy's TPS air-down/air-up display and stop it manually when it reaches pressure. I does get hot (not unexpected)... I usually wait a minute or two (while I disconnect and get the 4 tire system ready for storage) before disconnecting or moving the unit to let it cool a bit. Anyway, so far it has been reliable, consistent, and faster than I expected. I am very pleased with my purchase.

I've owned several portable air compressors over the years, and this is by far the most rugged and highest-quality unit I've used. The construction feels extremely solid, and nothing about it feels cheap or flimsy. The LCD control panel is easy to use, and being able to preset the target pressure is a great feature

Everything every 5 star review says on this thing is true, I was blown away at how fast it fills up the tires (from 30psi to 80 in less than 2 mins).. I did work it to its limits though, and once it gets hot it gets on protection mode and will only work periodically as the temp goes down.. I have a 3 axle toy hauler and aired down from 80 psi to 30 along with the tow truck (10 tires total) when I went to Dumont Dunes for Halloween weekend.. when it was time air back up it did 5 of the ten tires back to 80 psi no problem in less than 10 minutes.. then it got hot, it took me an hour and a half to air the remaining 4 tires back up because it kept shutting off.. still impressive though

This thing is a beast. It's super powerful and you should be running with this with at least a 2 tire at a time inflation system at min, or better a 4 tire at once to really take advantage of the flow which is significantly more than a single valve stem can flow. It had all 4 tires from 15psi back to 50psi in like 90 seconds or 2 min. My old pump would take closer to 8 ish min per tire.The LCD display and ability to preset the pressure to fill to is really awesome too. Not having to babysit it and shut off the pump to check is great. It will do quick auto-stops to self check the pressure and ensure it's good and then continue pumping.If you are out offroading and airing tires down regularly this is a killer piece of kit to make that better. I combined with an Outran 4 Tire Inflation Deflation System which worked out well.

Works great I air down all the time when I am wheeling or overlanding and since I air up to 60psi I need something that will do the job right every time. Works fast and efficiently.

I finally got a chance to use this. It works GREAT. Super simple to use and aired up the tires on my Jeep from 12 to 41 psi quicker than expected. Easy-to-see LCD display, simple interface and quality parts. Air hose is long enough to easily reach all 4 tires. Easy grab handle on top and the battery connection clamps feel pretty solid.It does get a bit hot when I have to do all 4 tires after a day of off-roading. But I just put it in the back and let it cool off for a bit before putting it back in the bag.Very happy with this purchase!

Great compressor, tyres dropped to 18 PSI for sand dunes. All 4 tyres inflated back 35 PSI within 7mins. Solid build quality, its a beast and had now issues with my F150

Excellent solid compressorIt took 45 seconds to inflat a tire 275/65/17 from 14 to 29 psi
