    4 out of 5 stars
    Big buttons and large display.
    I'm happy that this auto-reads your pressure once connected. Saves time from having to undo the pump, to check the pressure with a metal gauge. Buttons push in deep (easier with gloves, so you know the click registered).This works well at pumping to 35 psi. It also came with courtesy items: 4 Spare Dust Caps (1 metal lined), and a bike adapter! Glad to be prepared with this in the car.Quick guide for noobs (updated after talking to support):1) Make sure your car is in PARK, and put your emergency brake on for safety.2) Turn ON your car's engine while in park. (This updated model is designed for the engine to be turned on. This prevents your battery from being drained. The pump is powerful, so your battery might drain if you don't turn on the engine.)3) Unlock your doors, and keep 1 door open if you can. (So you don't lock yourself out. But if on the freeway, don't keep your driver door open.)4) Plug the pump in your lighter. (The display should turn on.)5) Press the light button to test there is power. (If not, pull the plug out. Push in again, and rotate in case there was grime in your slot.)6) Find your recommended tire pressure: look on the inside of your door. You can also check the tire. (Use the door number unless you got aftermarket tires. My tire gave a Max number of 44 PSI, when you DON'T want to pump that high. You only want to pump to 35, as the door says.)7) Go to your pump to set your PSI number:-a) Hold the Plus sign a few seconds until it blinks. b) Release. c) Keep pressing Plus or Minus until the number goes to the PSI goal that you want to pump. d) Release the button, wait, and blinking turns off.8) Don't press the ON button yet. Now connect the pump to the tire. It will give your tire PSI.-a) If the number is going down, then you didn't get a solid connection.-b) So take it off. Align the hole (rubber ring). Push in hard until you hear air leaking. Then quickly close the value. This got me a stable number.9) Now press ON and it should pump. It stops at your number.-a) If not, turn it off, take off the connector, and recheck your PSI with a metal gauge. (For first-time use, make sure your unit is good. The pump should give you a PSI number that matches your metal gauge with a +/- difference of 2.)-b) Then re-attach the connector and press ON. (The pump won't start if your tire pressure is already higher than the SET number or tire rating. Don't overinflate!)

    Reviewed in the United States on December 17, 2016
    Wow, this PI Premium Digital Tire Inflator was the answer for me!! With my tires way low on psi -- and the arrival of the unit this afternoon -- I couldn't use it fast enough. When my warning light came on stating low tire air pressure a few days ago, I could not find a gas station air pump that was working.

    I do live in the outskirts of Chicago -- 40 miles west and today was the last day it would be above 0 degrees. IT IS COLD IN CHICAGO-LAND and tires lose air quickly when you leave Summer/Fall and go into the Winter months.

    Knowing that tomorrow's temperature would be under 0 degrees in my garage, I immediately read the very clear instructions that came with the unit and proceeded to handle filling all four tires. As the instructions state, do know what voltage your car's power outlet can handle, along with how much psi is needed for your particular car model. You can usually find that tire information on the insides of the door panel. I drive a 2013 Kia Optima and verified I had 12.0 volts which is what this unit requires. FOLLOW THE SIMPLE INSTRUCTIONS and you will have all four tires, if all need air, completed in about 10 minutes or less -- as was the case for me.

    One important instruction was to insert the power cable into the 12V and THEN START the car's engine. Seeing that instruction -- in the simple, easy-to-read pamphlet provided -- was important since many individuals might start the car's engine and then insert the power cable. That may cause fuse to blow. I'm not sure on this point -- but I always follow the important instructions when it comes to car engine's and power outlets -- VERY IMP!

    I cannot believe how they have improved on the various features of Tire Inflators. For the last 10 years, I utilized an air inflator that ran on a battery and had to be maintained often i.e., keeping the unit charged. The unit finally "died on me" after ten years of good service. It was time for me to convert to the "digital" tire inflator...smile...and it is going to make my life so much easier. With this current P.I. inflator, once you set the psi -- which for my car was 33psi, it automatically saves that setting after you fill the first tire. When you get to the "set" button, it will give you the various measurement units. For me, I wanted "psi" and when it appeared, I then set up my 33psi for air tire pressure. It automatically shuts off air inflator once it gets to the setting you input. Once your tire(s) is inflated, you then shut the air compressor button to "off" and remove power plug from the 12 volt unit (cigarette lighter).

    IMPORTANT: All of this is contained within the simple and well-written instructions on third page entitled, OPERATION INSTRUCTONS." Read it so you know first-hand that you are following instructions correctly.

    What great features - made the task so simple and easy for me. I highly recommend this product. Thank you, P.I. for offering it on Amazon. Since I'm an Amazon Prime Member, I received the unit with free shipping within two days. It was so convenient. Being an independent woman, making wise and important purchases such as this one gives me peace of mind.

    I purchased this to use for small jobs and as an emergency inflator to carry in my vehicle. After I received the pump (delivered on time and well packaged), I used it to inflate the tires on my road bike, which the pump accomplished quickly (inflated from approximately 25 psi to 105 psi). The instructions were clear and concise. The hose attached to the tire stem with no trouble; it is a screw on type, not a quick release, but was not difficult to attach and remove. The digital gauge was easy to read, and seemed reasonably accurate (as compared to the pressure shown on my manual pen-type gauge). The digital gauge can be preset to shut off the compressor when the desired pressure is reached, and worked as advertised. The pump was noisy, as mentioned in some other reviews, but did not seem inordinately so as compared to other air compressors I have used. I then used the inflator to fill the tires on my small SUV; each tire had about 26 psi, and I filled each to 32 psi. I was able to reach each tire (front and back) with no problems (plenty of length on the power cord and hose). The compressor filled each tire in less than 4 minutes per tire, and shut off after each reached the preset 32 psi, so was never in use for more than the 15 minute limit recommended in the instructions. After use, the power cord and hose fit easily back into their respective storage compartments, and the compressor fit nicely in its cover. This product worked perfectly for its intended purpose, and is well worth the money. I was also impressed that the company co-founder, Yolanda Cooke, sent me an email after I ordered to introduce herself and let me know she was available if I needed any assistance (while not a guarantee of good customer service, I do appreciate the extra effort and personal touch). The compressor includes an adapter for use with wide valve jobs such as an air mattress or beach ball, and a 'needle' for use with sporting equipment (football, basketball, etc). It also includes 8 extra tire stem caps). A good bargain and highly recommended.

    5.0 out of 5 stars Great little air pump.
    Reviewed in Canada on December 17, 2017
    Used it a few times and it works quite well. Cable is long enough and motor isn't too loud. Cable management needs a little work as it's a struggle to push the power plug and cables back into the unit. The lcd lights up so it's easy to see at night. Two minor issues. 1. the reading seems to be off by 0.5 to 1 psi (under). So I always set just a little higher and pump more. 2. The attaching of the nozzle is a screw type, so expect some air loss as you try to unscrew the nozzle from your tire. Overall, a good buy and useful, especially in an emergency.

    5.0 out of 5 stars Muy satisfecho
    Reviewed in Spain on February 2, 2018
    Es más compacto de lo que me esperaba, y cumple con su cometido a la perfección. Es muy práctico y extremadamente fácil de usar: enroscas la válvula, seleccionas la presión deseada, le das al "ON" y él se pone a inflar, y se apaga solo cuando termina. Cuando lo conectas al neumático siguiente, recuerda el último valor de presión usado y a menos que lo cambies, si le das al encendido, ese es el que usa.

    Para lo que vale y el tamaño que tiene, la velocidad de inflado me parece más que correcta. Para uso intensivo no lo veo, pero para lo que lo necesito yo (inflar las 4 ruedas del todoterreno, de vez en cuando, después de bajar presión para hacer un trayecto rocoso), cumple de sobras.

    Ruido, lo hace, pero no veo que sea excesivo (es un compresor, al fin y al cabo), y más siendo tan pequeño (y barato...).

    Se agradece que la conexión con el pitorro del neumático sea de rosca: se escapa un pelín de aire al desenroscarlo (hay que ser un poco rápido), pero es mucho más cómodo poderlo enroscar y olvidarse que tener que estar aguantando la válvula, como era el caso de otro compresor que tuve.

    En cuanto a precisión, en mi caso (quizás varíe de unidad a unidad), infla un psi más de la cuenta (nada grave). En el manual pone que por el aire que se pueda escapar al desenroscar, es mejor marcar un psi más de lo que requiere el neumático. En mi caso, la presión debería ser de 23 psi, así que marqué en el aparato 24 psi, y al comprobarlo en una gasolinera, me marcaba 25, así que recomiendo poner la presión que indique el fabricante y ya está (aunque también depende de lo rápido que sea cada un@ desenroscando la válvula jeje), pero en todo caso, un psi de más de supone un problema. Lo importante es que los valores de inflado son consistentes (no infla una rueda más que otra).

    Muy satisfecho con la compra, me esperaba un producto de calidad inferior. El único fallo que le veo, por poner alguno, es que el cable de corriente es algo complicado de enrollar como para que quepa en el hueco que trae para guardarlo (pero se puede dejar enrollado y con una gomita y ya está).
