I got this after the one I had died. This thing is great! Compact, easy to use, and has long battery life. Great to just leave in my trunk on road trips and saves me money and time from having to stop at a gas station/rest stop. I have one tire that is a little leaky, so having it in my car at all times helps me get back on the road all the time. The settings are easy to see with the digital display, and the automatic shutoff feature is my favorite, so I can set it and forget it.

Unlike the majority of inflators listed, the Etenwolf is manufactured to provide accurate results. As tyre pressure accuracy and consistency is a central safety consideration, I would suggest calibration would be the primary design criteria. In achieving internationally recognised calibration standards, Etenwoolf have not however compromised on useful features including a low pressure inflator and multi-function torch. The compact size, cordless design and useful battery life contribute to its ease of use. Well worth the extra cost for a fit-for-purpose product.

Used it on a few SUV tires and its does a pretty good job..Takes about 5 minutes from a complete flat to around 50 psi.Runs a tad warm and not too noisy. Its better to let it cool down a bit after each tire though.Time will tell how long it last but first impressions it does it job and small enough to leave inside a trunk.

El equipo está super bonito, muy bien diseñado e infla rápido las llantas, el problema es que no infla tantas llantas como dice, por ejemplo, fue probado en un mini cooper, y se les aplico a 3 llantas 15 psi más o menos (de 20 a 35 psi) y 1 se lleno desde 0, ya con eso solo quedo una rayita de 4 de carga del equipo (esto fue durante el primer uso y tras haberlo cargado al máximo), así que es muy fácil de transportar (es minúsculo), ligero y muy bonito, pero para inflar todas las llantas desde 0 no alcanza, es más que nada para una emergencia.
