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

So this is not my first time using portable air compressor but this is for sure my first time even seeing an portable air compressor with a build in preset psi ! What a game changer it is ! you no longer need to stop your air compressor discount the air hose for the tire check what air pressure you have there now and continue to pump more air if its still to low. Not with this unit you dont ! You preset what air pressure you want turn it on and sit back and relax ! however you won't have alot of time to relax because this is a duel cylinder air compressor so it pumps air super fast ! To fill up air in the tire from 10pis to 33 psi in car it took under 1 minute . But this been a heavy-duty air compressor it can be used for trucks cars and anything .It dose comes with few attachments and very long air hose. Now for the air hose I dont know how well its going to last but I mean hoses are cheap online can always buy new one or better one. I have tested it few times with different psi presets and for the most part it dose the job very well maybe sometimes its about 1psi off but its not the end of the world . As the air compressor runs it turns off few times during the process I assume that it is checking the current psi as the air flows you can't read the true psi in the tire. so thats good . So overall I am super happy with this air compressor lets hope it lasts few years

Been using for over a year now. Waited to see if it was a good choice or would it not last. I off road often and this has always got the job done good quality. with the bag and compact size it takes little room in back and noise level not a big deal. Worth the cost

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 !!!

I use my class-C RV offroad on sand and air down to 15psi on average. Getting back to 80/65 psi on 6 tires is a lot of work. A friend started the same time i did on their rig with a generator and pancake 110v home compressor. The gauge is way off. I had to to to about 95psi to get to 80 using my trusted digital pressure handheld gauge and a manual/analog dial gauge. It's consistent. I waved at them as we left and they were still on their last tire. So, it's pretty fast. Alligator clips, so it's not an ideal connection. Wish there was a version that came with an Anderson/XT90 or other connector that can take the amp load to quick connect. I just got the 4-way hose kit. Looking forward to being even faster next time i use it with easier setup. Nice quality parts.

I’ve used it about 1/2 dozen times to inflate tires on two vehicles 37” and 34” tires from 18psi to 35 psi. It’s crazy fast and easy to use. However the calibration seems to be getting off the more I use it. I now Inflate one tire while watching the psi on the dash and when I get the pressure I want , I then set the compressor to whatever it is reading to do the other tires. For example , to get the tires set at 35psi I now have to set the compressor at 29 psi and it Will consistently put the rest at 35 dead on and shut off. The first couple of times it used it , it was spot on so it’s concerning the calibration is drifting. It’s a bit heavy and the bag is so so but other than that I love it (especially for the price )

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

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 compressor It took 45 seconds to inflat a tire 275/65/17 from 14 to 29 psi
