GSPSCN Tire Inflator Heavy Duty Double Cylinders, Portable Metal DC 12V Air Compressor - Car Accessories, 150PSI Tire Pump with Adapter for Car, Truck, SUV Tires, Dinghy, Air Bed etc (Titanium)

Very durable, easy to use, long cable so it can reach as far back, take up little to no storage space and inflate tire at a good speed

Requirements for my purchase:- need max "air pressure" to be at least 150psi capable knowing I probably wouldn't get 150psi of true air pressure cause I don't have a vessel strong enough for this test. But I can test with a vessel filled with water.- needs to be 12v complaint with + and - terminals exposed. Don't care about terminal connector for initial tests. Connectors will be decided after testing- needs to be portable, small, efficient, work as pure a air compressor should to inflate things and be durable for accidents from a tail gate or out of the truck.- price is a factor in regards to requirements, features, safety features, durability, quality, performance.Results from tests all passed with flying colors. The pressure gauge works and was tested alongside with another gauge that was already calibrated.The hoses the package came with held 100psi of water in a soda pop bottle for 20 mins. No leaks, no bursts and the pressure inflated to 100psi so quickly I was scrambling to shut off the pump before starting my test.My test comprises of a 1 way air valve with 20ft of 1/2" hose capable of 150psi air pressure into my pump, while other side of the valve contains water filled container to be pressured.

Pumps fast, feels hefty and well built. The piston covers by the handle are plastic, I would have preferred metal for heat dissipation, but what can you do.?. Like I said, the machine is mostly metal and seems well built. Tested it on the wifes car. No issues and filled all 4 tires reasonably fast.

TLDR - It's a good quality unit for the price and it'll get the job done better than most other similar products in an emergency. It's not intended for heavy use - just once in a blue moon when you're in a pinch. You can add a regulator and a tire chuck if you want.It's a great little emergency compressor to keep in your trunk. The quality could of course be better, but it's much better than similar products in this price range. It truly does achieve 150psi (which I had my doubts about before I tested it) and it took about 2 mins to inflate my SUV tire from 15psi to 32psi. It'll definitely do in a pinch. The air hose and surprisingly generous power cord should be long enough to reach all 4 tires from the driver's seat of any standard passenger vehicle. I recommend buying this with a small tire repair kit so you can truly fix a puncture on the road without having to call someone. It does come with a spare fuse for this unit, but you should also keep a spare car fuse if you power this compressor through the 12V cigarette lighter plug in case you happen to blow the one in your car.The tire hose attachment is screw on and the air pressure gage on my unit reports a pressure of about 5psi lower than the true value, which is slightly inconvenient, but also not a big deal in an emergency situation. This product does NOT come with a regulator of any sort, so it'll just keep pumping until it either burns out, the fuse blows, or you manually turn it off. On mine, I replaced the screw-on air fill adapter with a standard 1/4" dual tire chuck and installed an in-line regulator (both of which you can pick up for $25 at any home depot) for easy uniform tire inflation. Overall, it seems to work pretty well and I'm happy with it for the price.

Such a great air compressor. Heavy duty. Fast inflation and great quality product at a good price. Lightweight with an easy to read guage

This tire inflator worked as needed. We needed it to inflate a camper tire to 65 psi, from 40 psi. It took a few minutes but got the job done! We tried others but they stopped at 35 psi. There is no auto shut off on this one but there’s a very accurate gauge on it. Also, it hooks to the car battery, it does not have a 110 plug. Small, compact and comes with a nice storage bag. I would recommend.

This air pump is a beast! Fills tires fast, not too noisy and stable on the ground (does not dance around the driveway when in use or fall over due to its weight), only downside is the old school dial gauge. Very impressed with the performance and ease of use. NOTE: Would be just spectacular if they had incorporated a digital gauge, but definitely not a deal breaker at all!
