Goodyear i5000 Cordless Tire Inflator and 12-Volt Power Pack

Received the pump when promissed, so far it has worked as advertised. I really like the auto shut off when the tire pressure reaches your selected pressure. Some advice, if you set the pressure for 32 pounds of pressure and the tire pressure is already at 32 psi or HIGHER the pump will not start, it only starts when the tire pressure is BELOW what you set psi for. I have already used it for the kids soccor balls, my vehicle tires (Ford F150) and my travel trailer tires, with air pumps that need to be plugged in the a power source, this would not work on my travel trailer because the standard 10 foot power cord would be too short for me to reach the trailer tires!. It also came in handy when having to winterize my travel trailer by pressurizing the water lines to blow out the water from the lines. Also, a great price for the convenience of not needing to plug it in to an outlet or cigarette lighter!

Very good machine, works like a champ. Wish it would tell me when it's full, rather than NOT starting on a tire that is already at full charge. It took me a while to realize this "feature". Great to be wireless!

I bought this for my husband as a gift. We have a camper and he wanted something that we could take with us when we travel that doesn't need electricity. The first one we received did not work (worked for about 3 minutes, then quit), but they quickly sent me a replacement and it works great! His father also has this pump, has had it for several years and is quite happy with it!

Be aware that you must cool the unit for 10 minutes after running it for 10 minutes so it doesn't burn out. I added about 4 psi to my vehicle tires and it ran for less than a minute per tire. It runs quiet for an inflator. The built-in lighted dial guage is very accurate, but kind of hard to read because the marks are small and close together.

Setting the target pressure is easy, you just twist the guage until a pointer lines up with the psi you want. The inflator automatically shuts off at that pressure and it is accurate and consistent. No switching back and forth between filling and checking with a separate tire guage and bleeding air to hit the target pressure. The setting stays until you move it again, so you can bring all your tires to the same pressure without re-setting it for each tire. No fuss like with a digital one. Super convenient.

I recommend charging the battery immediately after use and keeping it fully charged at all times. The lead acid battery will have the longest lifetime that way. Once the battery gives out, the only way to run it is directly powered from a 12V vehicle outlet.

The manual and the labelling of switches and sockets is a little confusing, but operation is not overly complicated. There are two switches and two power ports. You'll figure it out.

You could burn it out with a big job like completely filling an RV tire, raft, air tank, etc. unless you stop every 10 minutes. As long as you stay within the limits, this will be a good tool. Probably the most convenient way to maintain vehicle tire pressures.

Works great. This item has a way of pre-selecting the amount of tire pressure and you let it run until the tire is properly inflated. Good buy.
