Easy To Use, Works Well and a Great Carrying Case
Color: Red
Received this inflator for Christmas. It was very easy to use. After charging the battery I turned it on and was able to easily navigate the LCD information screen to select the bicycle mode and set the pounds of pressure I wanted my bike tire to be at. Touch the trigger and it began to pump the tire up. I set it for 40 lbs. and as soon as it hit 40 the inflator automatically stopped pumping. It brought the tire to the 40 lbs. relatively quickly too. I will have to wait and see how it will do with an automobile tire. I then used the inflator on a small sports ball and it worked quickly and well on it. I also like the convenient carrying case which comes with the inflator. The inflator and all its accessories fit well inside it. It is a nice compact case with a net pocket inside the top cover to hold all the air adapters and the instructions as well. The instructions were EXCELLENT. Written in good English with pictures and was easy to understand and follow. This was a big plus for me as I have had numerous items bought on Amazon which had instructions that were on very small pieces of paper in poor English with poor drawings. Hence, they were difficult to understand and use. I would definitely recommend this inflator. ... show more

Potente, fácil de usar y muy práctico para cualquier vehículo
Color: Red
Este inflador de neumáticos inalámbrico ha superado mis expectativas. Es muy fácil de usar: solo configuras la presión deseada, lo conectas a la válvula y comienza a inflar automáticamente hasta alcanzar el nivel programado. La pantalla digital es clara y permite controlar la presión con facilidad. Me gustó que no necesita estar conectado al automóvil mientras se usa, lo que lo hace muy práctico para llevar en el vehículo o utilizar en cualquier lugar. Además de neumáticos de automóvil, también puede utilizarse para bicicletas, motocicletas y otros artículos compatibles con los accesorios incluidos. La batería ofrece un buen rendimiento y el equipo se siente resistente y de buena calidad. Lo considero un producto muy útil para tener siempre en el auto, ya que puede sacarte de un apuro sin necesidad de buscar una gasolinera. Sin duda, volvería a comprarlo y lo recomiendo por su excelente relación calidad-precio.también cabe destacar que si se te olvida cargarlo puedes usarlo conectado a tu vehículo y siempre estará disponible en caso de que lo necesites. Este producto es 1000/10 para mi ... show more

Compact, east to use, and performs great
Color: Red
I use this on everything now. It has a great display. I use it to top off the air on my RV tires and it had no problem getting to 80PSI. At one point I was airing numerous tires and it shut off. I thought I had run down the battery but the display let me know the unit was overheating and turned off until it cooled down - what a great feature! Lots of accessories included too. ... show more

Great for the price.
Color: Red
Packaging was good comes in a box plus a handheld bag. I found out my 2024 car didn't have a 12v plug so i purchase this as a emergency. Used it today on my car just to top off the psi on all 4. I like that it has a auto stop and auto program, it topped off each tire from 33 to 36 with no issues. I also did the other vehicles but I did notice it start to get hot when I was filling the truck. 3 tires went from 35 to 37 and had one tire at 31 and needed to go to 37. I think it's not good for continuous use. It might need to take a break to cool off but I already did my rounds 8 tires and battery still has full bars. Recommend to get the extended warranty if you plan to use this on a consistent bases. It's on sale right now pick it up while you can. ... show more
