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

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

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.

Bought this to fill both car and pickup truck tires. It is faster than the tire inflators available at hardware stores for the same price. Pumped a 17" tire from 25 psi to 44 psi in 3 minutes. Pumped a pickup truck tire from 25 to 51 psi in 6 minutes.The pump comes with two power cords. One is hardwired to the pump and ends with a 12 Volt "cigarette lighter" male adapter; it's about 24" inches long (all measurements are estimates). The second cord has the female 12 volt adapter on one end and alligator clamps to attach to the battery on the other; that cord is about 60". Both must be connected to each other to get power to the pump.The air hose hardwired to the pump is about 24" and the pump comes with an extension hose that seems to be about 60". All in all there seems to be enough cords and hoses to be able to get from the battery at the front of a pickup truck to the rear tires in the back.THE PROBLEM: that 12 Volt adapter connection is weak. The connection needs to be tight, and I was required to check it every few minutes and squeeze the connection to make sure it was maintained. Every time I move the pump to fill another tire, I have to go back and reconnect.I'm not thrilled that the only way to attach the pump to electric is by connecting alligator clamps to the car battery. It is advertised as being attachable to a 12 Volt supply, but the instructions say not to do that, and the cord to 12 Volt male adapter isn't long enough to do that anyway. One has to know a little bit about cars to get all the connections right, and the average person probably couldn't. Trying to use this in the dark in a panic would be really tough. I get it that to have a pump rated at 200PSI, we probably can't plug it into the cigarette lighter, but it's still a bummer that we can't do it.The analog gauge on the pump is small, and I must be up close to read the numbers (10, 30, 50, 70, 90 etc. and tiny hash marks for the in-between numbers). The gauge is not backlit either, so make sure to have lighting overhead or a powerful flashlight if you need to pump up a flat tire at night.This pump comes with a bag (the black plastic-fake canvas kind) that fits all the parts if one is careful to arrange everything inside it before zipping. I feel like that bag is going to rip sooner rather than later.The primary advantages over my old pump are a) this pump is at least 4x faster, and b) my old pump is broken and this one isn't. I bought this with a gift card so it also actually cost me nothing except for the opportunity cost to buy something else. If I had to spend my own money, I'd want a pump that was easier to connect and was lit better, but to find that along with the ability to pump truck tires at a reasonable price without many negative reviews is VERY HARD---I really tried. Seems like there is a market niche here, so to all the mechanical engineers listening-c'mon and get to it!

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.

The best pump for the money

So far, so good. It appears well-made and it's far quieter than the previous compressor I had (different brand - finally died). It also inflates fairly rapidly for it's size and doesn't get hot nearly as fast. I like the fact that it also includes battery clips, in addition to the usual cig adapter. Best of all, while I had to fight to get my previous one back in its soft case, the provided soft case is sufficiently large that there is still more than enough room for a basic tire puncture repair kit, if desired. The only downside I can see is that the pressure gauge is small and imprecise (as opposed to inaccurate), with tick marks every 5 PSI. If you're like me though, you use another high quality gauge to cross-check so it's not a big issue. The gauge seems to be reasonably accurate though.

Lo compré hace tiempo y me salio demasiado bien
