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

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

Why did you pick this product vs others?:Small and powerful. Got me out of trouble plenty of times. A must have for any vehicle.

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.

Es muy silenciosa y es muy rápida para inflar

Very practical and of good quality

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.

Excelente bomba , buena respuesta del vendedor. Llené los neumaticos de mi carro rápidamente.

I clamped adapter socket to battery, hooked the hose up, plugged the cord into adapter, hit the switch and it pumped for less than 2 seconds. I thought it might be the fuse in the plug end but it isn't blown. Thought that maybe the battery clamp adapter might be faulty so I plugged it into a 20A auxiliary socket but still nothing. I haven't had time to troubleshoot it further, but the point is that I shouldn't have to.Added to the failure are some design and build quality issues. The clamps are quite small for battery posts. The wire gauge is very small for the job it's being asked to do, and the cable is quite short.I'm so glad that I was just trying to do a seasonal pressure adjustment , and very lucky that this didn't leave me stranded somewhere.Do yourself a favor and buy a better compressor.How is this thing getting the ratings it's getting? The clamps and cord would make it a 2 or 3 star unit...if it worked.Doesn't even deserve 1 star.*OK, so I took a closer look at the failed compressor and found the problem, or at least the first problem; the wire connections on the clamp on socket are terrible and the negative failed completely due to a bad solder joint. The wire should have been stripped back further and put through the hole on the tab, twisted, and then soldered. Also when the manufacturer soldered it they didn't get the tab hot enough for the solder to flow and bond well, and possibly didn't use flux either.The positive wire isn't any better. If you look you can see that many of the wires weren't soldered to the post.Very poor quality control and workmanship.Also, the rubber hose is just plain rubber with no reenforcement and very likely to be short lived and fail. It could even be a bust hazard at the pressures claimed as possible, but I can't test that yet since the unit isn't working.I'm very unhappy with this item.
