Portable Tire Inflator, Cordless Air Compressor for Car, 8000mAh Electric Air Pump, Portable Tire Inflation with LCD Dual Screen Pressure Gauge Emergency Light, Universal for Vehicles and Ball

This pump is small, but yet powerful.You can use on your bike, your car, your kids inflatable toys and even to charge you phone or use as a flashlight.It is not really quiet but to be honest i never had one that was quiet.I recommend to keep always charged and ready inside your car.

This little inflator was a surprise. It pumps up bike tires fast. It's nice to just leave in the car for emergency use and for adding air to our bike tires. Haven't tried to top off the car tires with it yet but I can tell that anything more than a few psi to such a large volume tire is going to take a while. The unit does get really hot right at the air output from the main body after about 2-3 minutes of constant running. It gets hot enough that it seems like running is much longer will likely reduce the lifespan of the pump at the very least.It would be nice if it allowed pressures in half psi increments for lower pressures, maybe anything below 25 psi for example. Mountain bike tires especially are sensitive to small changes in pressure. The gauge displays tenths of a psi but you can't set the desired pressure to anything but full psi increments.Still, this little pump is a trooper. It's easy to use and pumps like crazy given it's small size.

Wonderful! Pumps up a tire in minutes. It is a must have for every car. So many gas station compressors are broken now, or if you find a working one, you don’t have enough quarters. Easy to store in the glove compartment or under the seat & lasts through several fills.

This inflator is not fast, but it is easy to use and can work unsupervised. This unit turns off when it reaches the air pressure set point. I would still keep an eye on it while running, as malfunctions are always possible. It has two pressure indications, the current pressure and the set point, so you can see where the pressure is when you first connect. The button operation is straight forward, and it comes with different types of attachments. The only thing I had to check the manual for was the LED spotlight. Hold down the U button to turn on and hold down the U button again to turn off.In operation, it is not very fast at inflating, but it really is not supposed to be. It runs as well as other portable inflators I have used in the past and this AICEL unit is much smaller and runs on a Lipo battery. I inflated a car tire, and to go from 18 to 32 PSI took about 5 minutes. I gauged the rate of increase and it's about 0.1 PSI every 5 seconds (sometimes a bit faster or slower). The inflator tube and metal coupling gets hot during operation. There is a heat warning tag on the inflation tube. During my test, you wouldn't get burned, but it is uncomfortable to touch for more than a second or two. So, the pump inside is getting quite hot (expected). Finally, make sure to keep the velvet bag they provided with the inflator. The inflator buzzes while operating, and if you don't have the bag to lay it on or against, it will buzz against your hub cap or the road concrete. The bag will help to dampen the vibration.So far, I like this inflator. This type of device is getting stressed during operation, so I will report back if it lives a short life.Update Jan. 2023: Still going strong. I filled a slowly leaking car tire about 10 times and a couple of trailer tires. Still filling at the same rate for full size auto tires (0.1 PSI in 6 seconds). For smaller trailer tires, it fills a lot faster (3x or more). It does stop after about 12-15 PSI fill on larger tires. I think it is getting too hot and turning off, so you just start it again after a short wait. Better than the pump overheating. Get about two fills of car tires per battery charge. Much easier than moving vehicles or moving the compressor or fill tank around.Update Feb. 2023: Well, my inflator finally quit working. During my last car tire top off (~10 in total), it started making a raspy clanking noise that was not normal, and air starting to leak out through the inflator. I turned it off and let it cool down. I have tried to use it a couple more times since, and it makes the same raspy clanking sound and won't make any progress with inflation. In all honesty, I did not think this inflator is suitable for frequent inflation of car sized tires, and the description for the product mentions it is not suitable for truck tires. For emergency car tire inflation, a 12V inflator makes more sense (don't have to keep internal batteries charged). The instructions mention this inflator will work at a much higher pressure than the 30 PSI I was setting. I think for inflation of balls, inflatables, and bike tires this would likely last much longer. Downgraded from five to three stars.

Love this little inflator for long bike trips. I have an air compressor in my garage but obviously it isn't portable whereas this is tiny and takes up very little space in a backpack. Super easy to set your intended psi and let it go to work. Performance and quality have been great thus far. Battery life as well.Well worth the money to have in a backpack for trips on a motorcycle or in the trunk for road trips in a car. Could easily save your hide.

This pump works well. It's nice to have in the back of the car in case there's a flat, since filling air at a gas station can cost a bit. Having the pump is much more convenient

This is amazing! Its SO small!This is the smallest compressor I have seen for car tires! I have a much bigger compressor/charger in the trunk, and it's great...but this little thing is handier, takes up such a smallspace (it will easily fit in a purse or small bike backpack, etc). It has a lot of power for the size, and is a lot quieter than my regular, much larger emergency tire air compressor. It came with multiple tips, including the needle for filling balls, and filled two new basketballs quickly. This has multiple settings that I am guessing provide different levels of power per setting. A really nice feature is that you can set the pressure so it shuts off when that PSI is reached. It also comes with a pressure gauge. I do not have a car tire that needs filled, so can't give a review on that option yet. Another nice feature is that it comes with a "C" type charging cord, and you can recharge it right in the car right after you use it...no need to leave it plugged into a wall for 2 days like my other larger one. Also, fully charged, it can be used as back up power for phones, etc...a handy feature if you are using this with bicycles or camping gear.
