XiaomiPortable Electric Air Compressor 1S, Tire Inflator Electric Air Pump for Car Tires, 150 PSI Tire Pump, Cordless Tire Inflation with Digital Tire Pressure Detection for Car, Scooter, Bike, Ball

This air compressor has been a great to keep in the back of my car. I have had to use it on my tires a few times and it has been very helpful since getting a screw lodged into my tire. The unit was accurate enough for my needs and it works great despite me using it every day.When attached to my tire I can set it to the PSI I want it to be at and I can walk away because it will stop at the set PSI. Additionally I have used it as a battery and to inflate sports balls. All of the functions have been great and I plan to continue to keep this in my trunk to use it as needed.

What's not to like about this Xiaomi compressor? It has just about everything... the easiest to use ever! All you do is pop one side of the loop "handle" (which turns out is actually the compressor HOSE), and as soon as it snaps out of it's socket, the compressor is "red to go" (this is how it powers up). You simply screw the now loose end onto your tire's schrader valve, set your desired pressure (up & down buttons), press the center button, and off it pumps.This Xiaomi pump had it's first test on my wife's four Sonata tires that were all at a low (sensor warning) 24~26psi. It took about 3 minutes per tire, but it pumped all four of them right to 32psi from it's first USB powered charging, and it still had plenty of juice to fill several more auto tires. When used on bicycle tires, it would likely fill quite a few of them to 50psi in about the same time... and all from a pocket sized device. This pump is absolutely PERFECT for my motorcycle tires when out on the road with no place else to fill them (should I have not checked them before departure). And all for 50 bucks? Like I said, what's not to like??? So, I ordered two more for my other vehicles...

I don’t think I’ll ever use a hand pump again.My bike has Presta valves and the adapter for this compressor works great. I leave it on and it seems like part of the pump.Super easy to use and compact for what it does. I’m still trying to find a way to mount it on my bike, but even if I can’t, I’ll at least keep it in the trunk of my car for when I need it.I like that it turns off when it reaches the desired pressure.It’s very well built. Quality materials and display is easy to read.I also found a silicone cover/case for it on another site. I would recommend this to protect the pump against impacts or scrapes, etc.

I have three air pumps in regular use: a portable air compressor powered by cigarette lighter; a high-end manual Blackburn bicycle pump; and this Xiaomi battery-powered air compressor. The Xiaomi is noisy and slow but it includes a built-in pressure gauge that automatically shuts the pump off when the target air pressure is achieved. It is also very convenient to use, as measured by how long it take me to attach it or removed it from the tire. As a result of these two key features, I use it more often than either other air pump when inflating car tires or bike tires with a Schrader valve. I simply attach it to the tire, start it pumping, and return 5-10 minutes later to remove it.The Xiaomi includes a Presta valve adapter. However this adapter does not reliably open the Presta valve which means it cannot inflate the tire. So bottom line: this device is very useful for tires with Schrader valves but not useful for those with Presta valves.

I love it. I've used it to pump tires on my electric bikes, regular bikes, car tires and have zero problems. It's portable, has 3 different tips depending on your needs and loops the connector into its own port for portability and makes it look like a lock. If I could suggest one thing, make it function as a vacuum too!

Sometimes will use it when the tire pressure alarm light shows up, it’s very easy to use and portable

This portable air compressor is great. Very easy to use, sleek and minimal design. I like that it has usb-c charging. Only complaint is that its a little loud when its running. Very happy with my purchase.

So, when you buy a battery operated, compact compressor you know it will be less efficient than a regular one... but this is insane! It adds air pressure to car tires at a rate of one PSI per minute. If your tires need 5 PSI each then you better find 20 minutes! But wait, the battery only lasts for 10 minutes, and it takes 1 hour to recharge... So if you actually want to add 5 PSI to each of your tires, you better be ready to wait ONE HOUR AND TWENTY MINUTES!
