12-Volt Digital Tire Inflator - Slime 40022

Competent User: Used this pump for several years. I power it thru the cigarette lighter in my car. Its been very reliable and convenient to use. Saves a trip to the local gas station to check and correct my tire pressure. The power cord is long enough to reach all 4 tires. You need to be mindful of limiting the runtime to a few . minutes as it can easily overheat. So you may need to pump air in several spurts to get the tire pressure up to snuff. Not a problem, just a little more time. Good buy.

Cliente de Amazon: es un compresora pequeña pero cumple bien su función rapidamente para su tamaño lo unico que no me gusto es que se siente un poco debil la parte que se pone sobre la llanta como es nueva funciona muy bien pero con el uso puede llegar a desgastarse y fallar

Cliente de Amazon: Excelente inflador. Su tamaño es pequeño pero su potencia es bastante buena. Su uso es bastante sencillo y la pantalla de medición integrada es muy útil para saber la cantidad de aire que contiene la llanta. El único contra es que es un poco ruidoso cuando trabaja. Sin embargo, definitivamente recomiendo este producto por la relación calidad precio.

Irving Arrieta: Es muy sencilla de operar, el cable que va a la toma de corriente es muy largo por lo que no tuve problema para llegar a los 4 neumáticos. El manual viene en inglés y es muy importante leerlo ya que contiene información para mantener nuestro producto en óptimo estado. En resumen, solo no se debe operar más de 10 minutos seguidos o bien, dejarlo enfriar antes de volver a utilizarlo. El auto no debe estar marcha mientras se opera y los cambios de presión se deben realizar antes de ponerlo en marcha. También se incluye una serie de respuestas a posibles preguntas que podrían poner en duda el funcionamiento.

Conociendo todo lo anterior, es un equipo que ofrece mucho y que nos puede sacar de cualquier emergencia y además la lámpara incluida es de gran ayuda en espacios oscuros o de poca luz.

Laura: Me gusto bastante el producto, pensé que iba a tardar mas en inflar la llanta a la medida configurada pero es bastante rápido.
El manual dice que al llegar a la medida configurada se apaga automáticamente pero no es así y para mi gusto la intensidad de la lampara debería ser un poco mas alta, son cosas mínimas que para mi no hacen la diferencia y compraría otro producto igual sin pensarlo.

Robert Fitzsimmons: I've been using an inaccurate pump and an old tire pressure gauge for years before I finally became fed up with them and decided to look for something new. I came across this product, and after reading a few of the reviews I decided to buy one. I was skeptical about buying it due to a few negative reviews, but due to it's relatively cheap price I decided to go for it (besides, there will always be a few people that have something negative to say). I got it in the mail 2 days after ordering it, and after reading the instructions for 5 minutes I tried it on my car and it worked perfectly!

As soon as you plug it into your cigarette lighter and screw the tube onto your tire, it immediately tells you the PSI, so you don't need to buy a separate tire pressure gauge. The instructions are very short and very easy to understand, so don't listen to the people that said they were "confused" by the instructions (just take 5 minutes and read them). After you set your desired pressure, just set it down on the ground and press start. That's it! Some people have mentioned that it gets sort of loud... Maybe I'm used to the noise, but I didn't find it to be loud at...

Dr. Supriyo Roy: Product is different than one given. Inflates tire quite slowly. No auto function. Too much sound and vibration that you have to keep your hand firm against the ground. Also the gauge shows wrong pressure. When it showed 30 psi i swiched off the product and checkex with a pressure gauge and actually the pressure was 40 psi ! So actually it overinflated my car tyre. Very depressed with the product.

Alex: First of all I didn't purchase this to be a replacement for a real air compressor, and I wouldn't recommend it to someone for that purpose. I park in a ramp adjacent to my apartment, so I have nowhere to store or plug in a real compressor. I purchased this as a quick-fix solution for a couple tires on my car which don't hold air very well in the extreme cold we've had this winter. This gadget saves me having to either drive on under-inflated tires to a garage with a proper compressor, or having to use a manual tire pump out in the cold (that's just unpleasant).

With the understanding that it's not an industrial-grade piece of equipment, this device is actually pretty impressive, especially for the price point. It's a lot smaller than I expected, yet has plenty of space for cable and hose storage (the power cord is quite long too). The controls are very straightforward and easy to use, with big, glove-friendly buttons, and the backlit display is bright and easy to read. The auto-shutoff feature over-inflates the tire by about 0.5psi, so when you lose a little air from unscrewing the hose the tire ends up at exactly the pressure you specified. I also...

Steven T. Kirsch: I did a lot of research and this was the only inflator that would stop at the set pressure. I *love* that.

I read the reviews on amazon before purchasing and it works just as I expected.

What I love:
1) You can set the pressure once and forget it. It remembers you setting after you remove the power
2) It is lit so you can use it at night easily.
3) It stops when it gets to your pressure (in my case 45 lbs).
4) It is very small
5) It is very light weight
6) I keep it in my car due to 4 and 5
7) It is reasonably fast... about 30 seconds or so for a tire typically to top up a few lbs

Things to improve:
pressure is slightly inaccurate...in my case, had to set to 48 lbs to get 45 lbs. But the good thing it is rock solid consistent so setting to 48 will ALWAYS give 45 lbs.
It vibrates a lot. You set it down and it travels on the ground. I had to put a cloth under it to keep this from happening. This was the biggest surprise. Even putting rubber feet on it didn't cause it not to vibrate and "travel."
It is noisy (but that is pretty much expected I guess)

Other things:
Screw onto tire valve works well. People...
