Review on 🚀 TOPDC Dual Cylinder Air Compressor – Heavy Duty Metal Tire Inflator - Portable Digital Tire Pump - 12V DC 100PSI with Battery Clamp and 2M Extension Air Hose - for Car Tires, SUV, Truck, Bike, Air Bed, Basketball by Mondreka Rosenhoover

Compared to a professional or commercial compressor this is a generic consumer quality blower so I had my doubts. Rest assured, it's worth every penny.1. It's pretty quiet for a twin-cylinder engine.2. I have a Volkswagen Passat. The 12V connector is in the center of the console. Between the power cable and the pump cable, the connection easily reached all the buses.3. Charging only takes a few seconds. My tires were 27 or 28 psi and I inflated them all to 36 psi. I would say maybe 30 seconds for each hoop.4. The preset psi function on the inflator is very nice and works well. The onboard sensor is likely to be accurate most of the time. I used a hand gauge for a good measure. It can deviate by about half a psi, so you can set the gauge 0.5psi higher than you want to inflate. Also if you unscrew the valve stem you will lose some air.6. The included LED light is very good. I haven't used it (only during the day so far) but I looked at it from an angle and it looks bright enough.7. Battery clips included if you don't have a cigarette lighter. In this case you may need to use the supplied air hose extension. Actually, my recommendation would be to get a cigarette power cord extender instead. Caveats: 1. As I mentioned before, I would say the pump is probably 1/2 psi off. Certainly not a deal breaker, but what you need to know.2. PSI increments are only 1/2 psi. It is certainly suitable for most applications. And again, you can't get much more accurate information than this with a tiny air leak.3. The case is very nice, but the hose must either be wrapped around the compressor or simply mounted there. In the short time I've been using it, the device hasn't warmed up at all, just slightly warmed up. You must test. Other reviews say this device is unlikely to burn out, but if you're pumping from scratch, be careful and control it properly. So this device costs *absolutely* $35 or so. Definitely a good idea to carry in the trunk. You can also be a hero if necessary. Always carry jumper cables, a roll of duct tape, a flashlight, torches/triangles and a repair kit. Add this to your emergency kit and you're truly prepared.
