   Works like a charm!
   A,azing simple device for pop up the tire air pressure. I did have a portable 200psi electricity air compressor, but only have to plug in DC power and heavy. This portable, easy, and powerful, & use friendly device is so easy to use, screw in the tire air nozzle, turn on the device power, it will detect the tire pressure, adnust the desired pressure(PSI) you want(by + or -), then hit the power buttom again, WHOLA! It is amazing simple and easy. After fully charged, I immediately to pop 3 cars tires(3×4=12 tires), it aversage from 27 to 34 PSI, after that, the battery still shown 3/4 capacity. The device also can pop ballon, bike tire and any air pump equipment! Great with reasonable price!!

   Better than I expected!
   I can’t believe this actually works as well as it does. It does take a little while, but not crazy long to do a car tire. The auto stop and pressure increments are great. This is a handy item to have for emergencies and the every other week top off as needed. Very convenient.

   Fantastic little product with 1 major design flaw
   This little inflator is fantastic. I charged it up, topped off 2 scooter tires, and it still shows a full battery. Impressive weight and ease of use. I would absolutely love it…if it had come with a different hose. The screw on connector is a disaster when trying to fill your vehicle tires to a specific pressure. As you unscrew it, you lose precious PSI/KPA etc. For example, you inflate your car tire to 36 PSI. As you unscrew the connector, it is hissing and losing PSI. Then you check with a pressure gauge and you’re down to 31 PSI. I only penalized 1 star because you can easily fix this by getting a hose extender with a quick connect/release tire chuck for $5-10. For the combined price, you should just get the L4 or the L2 as the brand and products are good quality for the price and come with hoses that have the quick connect chucks.

   Bought two!!!
   Found this on Amazon in the pre-Black Friday sale for $20. Figured I’d try one out for that price.Arrived in package fully charged! I have used this twice for all four car tires and my motorcycle tires (and also tried it on one of those exercise balls and it inflated very well)…and still on full charge!This little air pump is awesome! It works very well on car/motorcycle tires. Doesn’t take long to inflate up to PSI. I am always checking my tire pressure, especially on the motorcycle, and my previous Sears drill/pump attachment has been losing it’s battery charging ability so I decided to try one of these.For $20, if it lasts a year it’ll be worth it. It’s small enough to fit in a larger glove box so keep one in your car (along with a tire patch kit!). It comes with various attachments, a charging cord (USB to USB-mini) and it has the capability to switch from PSi to the other metric gauges.Again, if you can find this on sale grab one! I decided to by another one after a few days of using the first, one to keep in the car and one to store in the motorcycle side case.Definitely recommend!

   It works!
   I bought this product so that the next time I needed to fill up my tires I could do it at home instead of going to BJs inflation thing at their gas station. What a pain that was. Anyway, the cost for the inflator was reasonable and I was concerned about how good it might be. Terrific purchase. Easy to use on my car tires and didn’t realize how low my tire pressure was when I attempted to use it. It worked great. I can’t tell you how long it took to inflate the tires of my 2006 Lexus because I turned it on and it’s supposed to turn off when it reached the desired PSI and I went in and watched TV. I came back in the garage and it mostly did what it advertises although on two of the tires it stopped before it completely inflated. Just replugged it in and it was resolved. This inflator works and makes things a lot easier for this 86 year old. Buy it, you’ll like it!

   Really great tire inflator that does shake all over the place
   I had some other inflators like this one and they shake all over the place if I place them down on a flat surface. Surprisingly, this over did not and it made a lot easier to inflate some tires.One thing I didn’t like about this one is that the attachment that connects to the tire valve has to be twisted on, whereas other inflators have easier to use lock mechanism. Minor inconvenience and I’ll still use it because it is still reliable and doesn’t shake all over the place but would have preferred it to have a better lock mechanism.

   Nice device, poor attachment
   For ~$20, the inflation device seems solid, is easy to use, and (nearly) inflated 4 tires from 36psi to the recommended 42psi on the initial charge. My issue is with the “Quick” Connector, which I found to be anything but. The cord connector is not very long, so unless you’ve parked perfectly, the tire valve stem will most likely cause the device to dangle. What’s worse, is that to secure the Connector to the valve stem, you must screw it on, rather than clamping it down as most bike floor pumps use.I thought that maybe the Michelin tires that came with my car (Tesla Model 3) or wheel covers were at fault, but after reading some reviews, it appears that others have struggled with tightening the Connector to the tire valve stem too. I hear hissing when attaching and even more when detaching the device, which obviously defeats the purpose.So while I like the device itself and only paid $20 on 12/17/24, the poorly designed Quick Connector attachment knocks my overall rating down to 3.5/5.

   Easy to Use
   I was initially hesitant to buy this product, but it has truly exceeded my expectations. While it’s not the fastest option for inflating tires, it gets the job done effectively. For example, my truck tires were at 27 PSI due to the winter cold, and it took about 8 minutes per tire to inflate two of them to 40 PSI before the device needed recharging.Pros: • Compact, portable, and easy to use • Convenient to keep in your vehicle for emergenciesCons: • Slower than a traditional air compressor • Lacks a dedicated compartment for storing the various air nozzlesOverall, it’s a handy tool for on-the-go use, especially in emergency situations.

    This tire inflator is a game-changer! It’s super lightweight and easy to carry anywhere. The cordless design is so convenient, and the battery lasts long enough to inflate multiple tires on one charge. The dual display is bright and gives accurate readings, making it simple to track the pressure.Inflation is super fast—topped up my car tire in less than 2 minutes! The preset function and auto-off are great for hands-free use. I also love the flashlight with multiple modes, which is handy for emergencies.Perfect for cars, bikes, and even balls. Highly recommend this versatile tool for anyone on the go!

    J’ai acheté ce gonfleur pour les pneus de mon fauteuil roulant. Format pratique qui ne prends pas de place. À emporter partout avec soi. Fonctionne très bien.

    Voy a explicarme, es el tercer inflador que compro:• El primero era portátil, pero con toma al mechero y un día dejo de cargar y de funcionar• El segundo era a través del mechero, se partió el conector del inflador y ya no se podía usar (con un solo uso)• Éste último es portátil y se carga usb.He quedado encantado con el producto, porque es pequeño, manejable, viene con todo tipo de boquillas y en mi caso lo compré con un descuento que lo hizo más atractivo.La calidad parece buena y los materiales resistentes, para un uso espontáneo de inflado de ruedas y balones.He rellenado las 4 (QUE NO INFLADO COMPLETO) ruedas del coche, una de ellas estaba flojita, y la batería ni se ha resentido. La boquilla es a rosca tanto en la toma del propio aparato como para la válvula del coche.La operabilidad resulta intuitiva a base de pulsaciones sobre el mismo botón y la pantalla es excelente tanto en información como en iluminación. Puedes hacer inflado libre o poner una cantidad hasta en la cual se para de inflar, como podéis ver en el vídeo.Pegas, que todo las tiene:La batería no es de 4.000mah sino de 2.000, tampoco sabría decir cuánto puede influir en el nº de inflados a realizar. Pero la realidad es que no cuadra en las especificaciones técnicas mostradas en la web.El tubo de inflado y la boquilla de salida de aire QUEMAN Y MUCHO después del uso (ya digo que después de rellenar las 4 ruedas). He optado por dejar enfriar el inflador y el tubo antes de guardarlo. Aunque es comprensible que queme.Además viene con una pequeña luz led para ayudar cuando la ocasión lo requiere.Lo mejor es el tamaño reducido y que pesa poco, en una de las ruedas el inflador quedó colgando porque no llegaba al suelo y no me dio la sensación de que se fuera a romper o desprenderse la boquilla de la válvula, porque es a rosca.Si en el futuro tengo problemas por los que tuviera que rectificar la reseña, así lo haré.

    Only had this unit for around a month..I first checked my sons car tyres they were all around 28-30 psi ..pumped them all to 32-34 psi.. then did my partners car it’s a little noisy and same result..then did my mobility scooter. And 2 tyres on a hand trolley.. all without the unit needing to be charged.. so yes I like this unit.. I just hope it keeps working as good as it has so far..Only complaint is it’s a little noisy, but it is a mini compressor so you would expect that..
