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

From the packaging to the unit itself, this feels really high quality. It works well, has nice features, but is not too complicated, its self explanatory. Will see how we it holds up and last, the pump and the battery. Thats one downside with these compart units vs the big tool company pumps is, the batteries arent replaceable/switchable, at least not easily or without disassembly. But the price is appropriate so its fine. I bought this primarily to pump up my foam sprayer for car detailing, and this unit in particular because there is a setting to maintain pressure, so when I use my sprayer and the pressure in the bottle depletes, this kicks on once the pressure falls about 5 psi below the set point, and pumps again till it hits the set point. Awesome. Other reviewers have mentioned this great feature, but have failed to list how to invoke the mode, as its not in the instructions, so here it is, hope this helps in the future: 1. pull out the hose to turn on the pump 2. press and continue to hold the light button (left side button at 9 oclock). 3. simultaneously hit the mode selection button once (the right side button at 3 oclock). There has been some mentioned of having to hit it twice, but maybe thats on older Xiaomi pumps). 4. you know its activated when a small clock looking icon appears on the display in the upper right corner. 5. now set the pressure you want to maintain and hook it up to your pump sprayer, or anything else that you might want to maintain the pressure of (just dont leave it on a rolling tire, lol).

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.

I grabbed this portable compressor for my Ninebot scooter and it has been clutch. It tops off the tires fast, the pressure reading is accurate, and the auto stop cuts power right at the target so I do not overinflate. Going from slightly soft to ride ready takes a couple of minutes and I am back on the road. The size is perfect for a backpack or glove box, and the metal body feels sturdy. The screen is bright and easy to read at night, and the built-in light helps find the valve in low light. Presets for PSI and BAR make it simple, and swapping between scooter, bike, and balls is easy with the included adapters. Battery life has been solid for multiple top-ups before I need to charge again. If you ride a scooter and hate hunting for a gas station pump, this is a five star fix. Compact, reliable, and genuinely useful every week.

I was guessing at the tire pressure on my electric unicycle, using a manual bike tire pump. I was very wrong. This gives me peace of mind and safety as it pumps to my setting.

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.

Works beautifully! Accurate reading and long battery life! Easy to carry around for an emergency and you can charge it via usb. Definitely a hit with this one. Comes with a screw on tip for quick release and application like the one that comes with a bicycle pump. Get this one foo. Orale

This is a super convenient and easy to use air compressor. My 70-year-old mother was able to use it at her house unassisted. I have used it everywhere from airing up a basketball on the playground to airing up a large tire on my three-quarter ton diesel pick up. Slightly larger than a cell phone, easily held in one hand. Have bought six others to keep in all of our personal vehicles, all of my work vehicles, and for my older mother.

Broke after less than 10 times use. Seems like the pressure sensor stops working, always displaying 264 psi
