XiaomiPortable Electric Air Compressor, 150 PSI Tire Inflator for Car, Scooter, Bike Tires and Balls - Cordless with Digital Pressure Detection

This is honestly one of the best little gadgets I’ve bought in a while. The Xiaomi portable air compressor is super well-built and feels like quality right out of the box. It charges quickly with a USB-C cable, and once you read the instructions (just once!), it's super easy to use—you won't forget how it works.One of my favorite features is the built-in flashlight, which really comes in handy if you’re using it at night. I mostly use it for biking, and it lives in my mountain biking bag. The battery lasts for months between charges, which is seriously impressive.It always gives me the correct air pressure, and I’ve used it a few times on car tires too—not from flat, but to top off or finish errands, and it handled it like a champ. People are always impressed when they see it in action, and I’ve had a few compliments just pulling it out.If you're on the fence, just get it. Super practical, dependable, and well worth the price.

This device is a lifesaver!Noise is minimal so you wouldn’t be loud.Battery life is enough for a couple wheels. Doesn’t charge through the car very fast , but I usually have my huge charging station from anker.Auto shut off works fine!

works perfectly , used on bicycles and for pressurizing pump sprayers , works perfectly , best part is the continuous mode where it out cutoffs when set pressure is reached and restarts when pressure drops , this is very useful for pressurizing pump sprayers while the sprayer is in use

very convenient and handy with my bikes.

It looks like a real estate agent's lock box with iPod controls on the front. However, the form factor is convenient for quickly topping off tires without the tangled mess of wires and hoses that comes with traditional car air compressors. The hose cleverly nests into the device and automatically turns it on and off. The plastic has attractive finish like an expensive gadget but is likely to get marred by the concrete floor in a garage, or potentially scratch your car rims or bicycle spokes as it dangles from its short hose. A more rugged, rubberized exterior may have been a better choice.Inflation time isn't very good but can be excused for the compact size of the device. I still keep a wired 12v air compressor in my car for emergencies, but I use this device at home just for topping off air in bikes and cars. I think it's too slow and the battery is too limited to rely on if you have a flat tire, plus needing to remember to maintain the battery.The unit I received had a Chinese manual and packaging, so it seems this is a gray market import or the inventory is allowed to mingle across third-party sellers, so it's questionable if a warranty would even be honored in the US. I was able to find an English manual online in PDF format, but the device is pretty self-explanatory if you've used an air compressor before.The various modes are a bit goofy, the units arbitrarily change between Bar and PSI. Bar units aren't used in the US market for cars, but PSI shows up in "Bike mode". Very strange, probably some Chinese->US localization issue... I expected the modes would remember the last pressure setting for your respective car or bike, but it actually forgets the setting each time you power the device off. It would be a lot more useful if each mode remembered the last setting.

I saw a review of it in YouTube. I got it, used it, recharged and put in my trunk. It always works. Friends and family were amazed by it, and severa bought one for themselves. It's a life-saving gadget. I've used it more than I'd thought. I got one for each vehicle. They're so reliable. Key features are having USB-C charging, and the fact that it packs a lot of current. It can pump four tires before having to recharge. Enough for saving your tires.So many times I've seen people with deflated tired almost cry next to an out-of-order pump at the station. I'm the one to save the day. Like a mild super-hero because of this relatively tiny gadget. They should be included with all new cars indeed.

This one’s great — definitely deserves a thumbs-up!

Quit holding a charge after about a year and a half and now won’t work at all. It was nice while it lasted, but it’s definitely not something you can keep in your road kit and rely on to work when you need it. I expected better for the price. I have cheaper air compressors that have worked for years but require a 12VDC connection, and I will be switching back to those for peace of mind.
