This COSENG tire inflator and jump starter is a very nice unit in a very crowded field. Its current list price is a bit much, but the current coupon price is probably somewhat less than if you were to buy separate units of equal performance and quality. The unit comes with a nice hard molded zipper case with a separate compartment for the accessories, that you wouldn’t know about unless you looked at the video on the web page. It and some of the accessories are not shown in any of the pictures on the web page. The unit has all the common features, controls, indicators and protections you would expect and also includes a very bright work light, that also can be used as a blinking red and blue emergency warning flasher. I tested the inflator by letting a few pounds out of one of my tires and then used the compressor with the auto shutoff feature to reinflate it. I then checked it with the TPMS and it tested correctly.
The unit can be recharged with the included cable with any user supplied high power USB charger. Speaking of charging, the unit can be used as a power bank to recharge your cell phone or tablet or most any other USB device.

This is very fast at filling tires. It is 2 to 3 times faster than the other ones I’ve tried. It doesn’t remember your previously entered value. Which is annoying. Another negatives about the tire filling is that it doesn’t remember your PSI preference. You have to cycle through different modes until you get to one that’s PSI and adjust the value there.
It also can start a car battery. I was skeptical but it did in fact start a truck battery that was very dead. That is a very convenient feature to have on an already useful tire filler.
This company makes another pump that is similar in specs and features, but a different shape. I have tried both and cannot really tell the difference in functionality. The other is a little cheaper and a little smaller. I’d pick that one over this one.

Powerful compact unit. Fits in my truck console.
All wire cable, clamps and HD plastics feel sturdy. Nice unit.
