This inflator is so cool -- I actually bought two. I needed one for the car in case of any tire emergencies and one to have at home for other inflatables like basketballs, bike tires, floats, etc., I really enjoyed how efficient this tire inflator is and how good quality it is. Considering I know nothing about this topic, but I know I need one, it was easy to figure out -- which is amazing if you're like me and are worried about its functions.This is made out of strong metal and has a small display that shows many units (including PSI, BAR, and MPA) to demonstrate how much air is needed. When filling something up with air, the tire inflator automatically stops when it is filled, taking the pressure off of you to figure it out. It takes a few moments to get everything filled with air, so it is speedy and efficient. To use it, I just turned it on and connected the tire inflator hose to the valve and set the desired pressure, and pushed the start button. It is rechargeable after a few hours and comes with a sleeve to keep it safe. A must-have in case of emergencies for sure!I was looking for a strong mini compressor to keep in my truck for emergency, blowing up my kayaks and mountain bike tires. I ended up purchasing this Norshire tire inflator and really impressed with it so far. It's pretty sleek looking and durable. I used it several times already and extremely happy with the performance. I like that it automatically shuts down when you reach the desired air pressure. I filled up 2 kayaks, two mountain bike tires and topped off my truck tires just to try it and it worked well. Plugged right into my cigarette lighter and charge right up again. Very portable. Affordable and a necessity for my lifestyle. I would highly recommend this Norshire compressor.The design of the device is very well done. It feels very solid and its compact size make it a must own for every car owner. It's very easy to use and it get the job done without any problem. The battery is enough to adjust the four tires of the car with a single charge. Of course it is not as fast as bigger inflators, but in 2 or 3 minutes is capable of pump up to 4 to 6 PSI. The charge takes a couple of hours to complete, but you can keep it charged and ready to use at any time. If for any reason you run out of battery, it comes with a long enough power chord that can be connected to the cigarrete lighter.It also comes with a useful bag and everything you need to inflate any other type of things such as bicycle tires, balls, matresses, inflatable pool devices, etc. HIGHLY RECOMMENDED PRODUCT!Lots of impressive qualities to the NORSHIRE tire inflator. I love that it's rechargeable, easy to move with and that it comes with a sleeve to keep it protected. The readings are good, it's easy to set your desired PSI and it shuts off when finished.Great for life on the road, and you don't have to worry about needing a cigarette lighter of wall plug to use it. An affordable option for the family.This works fast and accurately. I charged it up and attached the hose for tires and screwed the hose on my tire. I turned it on and it topped off the air quickly. This comes with a box of attachments to be able to do balls and bikes and inflatable items as well. Once back in the pouch, it stores nicely in my cargo holder. Well made for the price, I highly recommend.The specifications for this mini compressor are definitely over inflated!! I was excited to get this for my Harley and had the opportunity to test it out on a trip we recently made. Just prior, I fully charged it and when we actually needed to use it, the battery gave out half way on a motorcycle tire going from 25 to 40 pounds. And this was AFTER I discovered that the power switch is ridiculously sensitive and turns on just by packing it away. I had to use a worm clamp to slide over the switch to keep it protected. Also noted in the specs is that it has a touch screen display. Nope. The actual buttons are what are touch sensitive. Which brings me to another issue. Getting it set to the proper scale, in this case, to read PSI is an excruciating ordeal. Then, once set, it will not hold that setting while being packed away, forcing you to jump through hoops when you really don’t have the time to do so. On the plus side, it does pump up well (when plugged in) and shuts off when proper pressure is reached. Would I recommend? Not unless you can live with the above issues.Más de lo que esperaba. Todos los componentes de excelente calidad y muy buen performance.
