Portable Tire Inflator Air Compressor-20000 mAh, 150 PSI, Cordless with Gauge

I bought this brand after seeing in action, I used it on my Full Size Truck to top all 4 Tires air pressure, It is noisy and you must hold it with your hand while its working, It did not bother me, will work for an emergency flat so you could move your vehicle away from danger, Fix a flat tire on the road, put some air and later top it off with an Air compressor . This or Any other portable battery powered Inflate will NEVER Replace an Air Compressor, just keep that in mind, Good for emergency purpose. for a small car should be 100% serviceable . I have also used it on my wife's mini van to top off low air pressure to get rid of low tire pressure warning. overall I am happy with the purchase ,I highly recommend it. No more searching for air hoses at gas stations for me.

This is a real cool product that everyone should have. It is a cordless and portable tire inflator that can inflate tires for car, motocycle, bike, and balls. It is powered by a battery that is rechargeable. You can recharge the device by just connecting the USB cord to the power source and the device. This device can inflate the tire in less than a minute. Once you select the air pressure for your tire and press the power button, it will inflate the tire to the desired air pressure and it will stop by itself when it reaches the air pressure that you set up for the tire. The air pressure of the device is set in psi unit. If the maximum air pressure of your tire is set in other unit, you may want to convert it to psi unit in order to get the equivalent air pressure in psi. You can do this by just using any on line unit coverter. It is amazing to see how this small, cordless, and portable device can do such a great job. It can also be used as an emergency flash light. It does a wonderful job in inflating the tire of my electric scooter!

I was a little leery of using this product to inflate my Jeep Cherokee tires. So, I first used it on my gorilla wagon in storage and was satisfied with the ease and quickness of inflating the 4 tires. With the change in the weather here in GA, my tires psi was fluctuating enough that they needed to be inflated. This portable air compressor is all that it claimed to be! Each tire took less than 5 minutes to inflate from 31 psi to 35 psi without the need to recharge the battery (another concern I had). I am extremely pleased that I chose this product.

I put this air compressor to the test the same day it arrived since my reason for such a purchase was to finish inflating my car tire from the night before. I had to use a foot pump, which took quite some time that night, and only filled it enough so I could drive my car the next day... about 22 PSI! My initial review is 5 stars since its functionality and the way it worked for me was exactly as advertised. It's compact, smart looking, and all the function buttons are in one small, tight group. In some places, the instructions are a bit cryptic. Probably written by someone who doesn't fully understand English or a poor translation from Chinese. DO NOTE that it is NOT quiet, but that is to be expected, I guess. It's just a bit noisier than I expected, but not intolerable. For an automobile tire, at the default, preset pressure of 36 PSI (which can be adjusted to your own desired level), it pressurizes a tire a tenth of a degree of pressure every 2 to 3 seconds. I was able to check and bring up to full pressure the other 3 tires, as well, which were hovering around 30 PSI (well below what they should have been) in about 15 to 20 minutes (all things necessary in that process taken into consideration). The unit stops the moment it reaches the pre-set pressure level. Just flip the lever quickly to disengage the hose from the tire valve so you don't lose any air pressure. The hose coming from the air compressor is short so if the tire's valve is near the top of the tire, you'll have to hold it or just let it hang while it's filling the tire. If you're able to let it rest on the ground, note that it will move around slightly because of vibration from the compressor. Not a big deal unless you don't want it to get scratched/dirty/muddy from being on the ground. If you ARE holding it, be sure not to block the air holes for cooling on the bottom and back of the unit. I also found in the process of moving from tire to tire, just ordinary use, that the compressor's hose loosened slightly, allowing air to escape when I was filling one of the tires. So just make sure the hose is securely and tightly screwed into the compressor each time you start to use it. I didn't notice that the compressor (the black box) itself gets warm when it's working but the compressor's hose DOES get VERY warm, especially as it gets closer to the unit itself around the area where the orange rubber piece is; hot enough that you'll not be able to hold it for very long. Again, not a big issue. I just let it cool down for a couple of minutes before removing the hose from the compressor. After completing the task of making sure that all 4 tires were fully pressurized, there were still 3 out of 4 bars on the battery level indicator. Over the next several months, if there are any unexpected changes in the way the compressor is working, I will make an updated review. Again, my overall review is 5/5 stars.

I maintain six bicycles for the extended family. In my 70's, manually pumping tires has become a chore. This device has made my life much easier. Just connect to stem valve, push center button to activate, and walk away. The device takes care of the rest. The device is sturdy; one charge lasts a good while. It takes a bit of thought to figure out which setting buttons to push, but that is to be expected (I am a trial-and-error guy, not an instruction reader). Some observations: > It is noisy, but that is a matter of physics > It does get warm, but, again, that is a matter of physics > Display is very readable and obvious > Once you have established the settings, operation is plug-n-play > Screw in the air tube tightly to top of device; make sure there are no leaks I do a lot of bike riding; tire pressure is critical; this device has made biking activities more pleasant. Not having to hassle with manual tire pumps is great. As Forrest Gump put it, "That's good. One less thing!"

I finally got a chance to use this today. Now that the weather is getting colder I needed to add air to my tires. The pump was somewhat easy to use. I had to read the instructions to figure out the sequence of buttons to press. Once I set the pressure, it did all the work. I didn't even lose any bars on the power monitor after inflating 4 tires. The light and the power bank features are nice add-ons. Have not used them but it is nice to know they are there. I keep this in the 710 bag from Blipshift in the frunk of my 911. Perfect fit.
