The operation of this device is okay but is in some ways odd or not so intuitive.To connect the inflator hose, you connect the shorter hose first. Then, connect the inflator hose. I’m not seeing yet why they didn’t make it just one hose and the connection on the tool a standard size in the first place.There are 4 different preset options: car (36PSI), moped (36PSI), bicycle (60PSI) and ball (8PSI). All four are preset PSI settings which can be changed. BUT, the machine doesn’t seem to recall the last setting. So, if you set the moped setting to 30PSI, the machine will revert back to 36PSI if restarted. This is a huge disappointment. Imagine having 4 saved presets that recalled the last setting?!? That would be awesome.So, select a preset. Just adjust the PSI with the ‘+’ or ‘-‘ and then, hold the ‘AIR’ and it will start the pump. If you press the AIR button, it will stop the pump. It also automatically stops at the PSI setting you’ve set yourself. Loudness is as expected for an air pump. Not that bad but it is loud as these things will be.Odd lag/delay: When you first turn it on, the battery percentage is shown for 5-6 seconds. You cannot press any button to get past this initial screen.Odd reset of PSI: You can cycle through the presets by pressing the ‘SET’ button. So, cycle through. Stop at a preset. Change the PSI setting. Decide to cycle through and that change you’ve just made is reset back to the original preset PSI set by factory. So, I mentioned that this machine doesn’t recall but even on the same power cycle, it will revert back to the factory preset. Be forewarned, in case you thought you changed the PSI but it reverts back.It functions as a power block with USB out. Nice, I suppose. Can come in handy.Comes with a cigarette lighter adapter with 2.4A USB output and an ~11″ USB-C cable. A couple adapters for inflating balls/sports equipment. An additional adapter which is an opposite converter of the the second hose to the machine… Odd.It’s a cool little gadget which can be charged via USB. For camping or just outdoor activities, I can see this saving the day. Add a BioLite to your kit and you’d be set.

Update.. I drained this thing down until it turned off.. I guess it does have “close” to a 4000 mah battery.. But it seems to be about 300 mah short of that.. either that, or this thing does not fully drain it down.. I can tell you that it drained it down so much that the screen would not even turn on any more.. But as you can see, after fully discharging it, and then putting a meter on it to test how much power went into it, to fully charge it.. As you can see, it only came up to 3,741 mah, not the full 4000.. Since these types of batteries usually have a charge to more than the advertised amount.. I have had up to a couple hundred more then advertised amounts at times.. First full cycles and it is close to 300 short.. enough said..I upgraded the rating to 4 stars because it did have a larger battery then what I thought.. I guess the percent of charge left is not very accurate..Original Review..I first filled 2 tires for a bicycle.. They were 24 x1 3/8″ tires.. I went from 35 to 65 psi in each of them.. That took 24% of the charge, from 99% to 75%.. Then I charged it to 100%, filled just one of my p205/60R16 tires on my 05 Sebring from 26 to 36 psi, and it took the charge down to 49% left.. or used 51% of the battery. and that tire took 3 minutes 38 seconds to fill.I checked the pressure with my pressure gauge after it stopped, and it was fairly accurate.. Within 1psi of what this read when it stopped..When charging, I found that off of my 2 amp wall charger, it was charging at 1.93 amps at 50% charge. So it does charge fairly fast.. It takes approximately 40 seconds to charge it 1%, but when you get to 99% and for it to hit 100%, it seems to take a few minutes.. Part of the reason for this is.. When it was on that last 1%, I checked and it was charging at 0.60 amps.. So it did slow down a lot at the end.Right now, I don’t think that 4000 mah is correct.. I charged it from 49% to 100% in about a half hour, or 30 minutes.. at 2 amps, or 2000 mah per hour, that means it should have realistically charge only about 1000 mah in that half hour.. Not only that, but my USB meter, only read a little over 1000 mah added to the number to fully charge it from a half a battery too..One thing I did notice.. On the listing it says 4000 mah capacity.. On the side of the compressor box, it says 2000 mah 7.4v.. If you had two 3.7v batteries in it, then that would be accurate.. But since I already know that there is no way to put 2000 mah in a half hour through a standard USB charger, at a 2000 mah an hour charge, this makes me think that either the 7.4v part is wrong, or someone did not put in the right batteries.. Either way, the capacity of the battery is only half what is advertised.The device is small and portable. I like that it comes with a bag to put everything in. The light on it is decently bright to see what you are doing.. But my big problem is. Since it only has half the battery that they advertised, and by looking at the other peoples reviews, they are having the same problems / results as me.. This makes the backup charger useless since it is not very convenient to carry something this big around to charge my phone, which has a battery in it over twice the size that is in this thing.. That would make being able to use both of them, at the same time, useless.Final verdict.. For just topping off a couple of pounds, or to use the light part, it works fine.. Nice and portable, but with such a limited battery in it (and wrongly advertised as being double what it is), that makes this thing very limited and it also makes it being used as a portable power bank useless too (especially when you consider my phones battery is over double the size of what is in this right now).. If it actually had the 4000 mah battery, I would have given it 4 to 5 stars..

If you’re expecting a device that will completely fill a flat tire on a car, you’ll probably be disappointed. If you expect to be able to occasionally top off a car tire, or fill smaller tires on bikes or yard equipment, this does a pretty good job.Compressor testing was done by adding 5 PSI to 2 car tires and completely filling 2 tires on a snowblower. Adding pressure to the 2 car tires took around 9 minutes. Filling the snowblower tires took only a couple minutes. Remaining battery capacity after filling the 4 tires was 25%. The pressure gauge read 2 PSI lower than my dial gauge, so accuracy is good. The display is somewhat difficult to read in bright daylight. The compressor shut off at set pressure. I didn’t test on bike tires or low-pressure toys, but don’t expect any problems in those areas.Battery capacity is claimed to be 4000 mAh on the Amazon website. Capacity on the device itself is stated to be 2000 mAh at 7.4 volts, indicating that 2 batteries are connected in series. On the company’s website, the 4000 mAh is spec’d at 3.7 volts, so at least mathematically it pencils out that the device has 2 ea. 2000 mAh batteries. I didn’t have any direct way of measuring battery capacity, since the batteries are sealed inside the device.I used the compressor to charge up my cell phone in order to get some idea of battery capacity. Charging from 10% to 100% calculated out to be almost 2100 mAh. It took just under 4 hours to charge the phone, and there was still 29% charge remaining in the compressor. That might come in handy in a long power outage situation. I wouldn’t carry it around as an auxiliary charger though.All in all, it seems to be a well-built device. Noise is as expected for this compressor. With twice the battery capacity it would get 5 stars from me.
