This is an absolutely amazing product and I would highly recommend anyone to have it in their car. This is my second Helteko air compressor as it is for my wife's car. We both see the value of having one in each of our cars, having mine saved me the last time I had a flat tyre. Compared to the previous version, I particularly like this one because of the increased versatility! The AC/DC option allows you to connect to a car cigarette lighter or a standard electrical outlet. I found this additional option extremely useful as it allowed me to easily inflate bike tires, basketballs and soccer balls at home. While slightly larger than the previous version, the new design features a handle that makes it much easier to move the compressor from tire to tire. All in all this is a great product, very easy to use and I recommend you buy it for yourself or your loved ones.
